Transition FAQ's
Q: On L1.4.9 (NEW) Are all the bays required to be designated with a DC power source label at the top front of the bay?
A: The designation in Figure L-10 for the power source is a designation for the power source for the bay and not the shelves within the bay. For example, when there is a fuse panel in the bay being powered from a BDFB/SPDU or power board, the power source for that fuse panel needs to be designated. The equipment shelves within the bay are not required to be designated with a power source. If there are two fuse panels in the bay, then there should be two power source designations on the top of the bay. Only bays that have power coming into them require the designation. The designation is not required on FOT bays and such.
Q: For Legacy “T”, what information is required on 145 Tags for Battery and Battery Return cables? The labeling supplement does not address this. Is it per the TP section “L”?
A: Follow Section L requirements for designating the 145 type tags on the battery and battery return leads.
Q: On 3.2 Volatile work activities: The maintenance window is no longer defined as the hours between 10:00PM and 6:00AM and is directed by AT&T.
If for example, we are running a 12-pack of coax cable from one bay to another and it is over live equipment (which is 100% of the time), this work would be considered 6-6 maintenance window work per the Ask yourself document. With that said if the onsite where the work is being performed would rather have us run the cables during the normal work day can they supersede the SMOP and approve us to work during the day vs. maintenance window? And if so how would we go about changing the SMOP to day work?
A: The AT&T Ask Yourself Handbook , specifically section 4, defines the AT&T Maintenance Windows. AT&T SMEs can override hours to meet critical business needs. AYS is owned by Network Operations, NP&E supports the requirements with our Installation Suppliers. I’ve added Alyson Peacock of the GNOC for any questions/support required.
Suppliers are required to arrange access and any coverage with the local operations teams.
Q: L1.4.9 - Figure L-10, is this meant to be a design or template? Do we include the
words POWER SOURCE followed by the pertinent information as in the format
shown with P-touch?
A: Figure L-10 is a template. The words “Power Source” are required to be designated.
Q: L1.4.9 - The label is to be placed "at the top front of the bay" would that be either side if this is an independent P-touch and centered if a single label?
A: The label can be placed anywhere at the top front of the bay. There is no location specified in the requirement.
Q: L1.4.9 - Figure L-10 indicates 1/2"-1" tape, Table L-3 for sizing has no specific
size lettering for this label, would 3/8" be appropriate for each line,
regardless of the width of the tape?
A: These designations fall under the "far end cabling information" field of Table L-3. We will expect to see 3/8" size characters for this designation
Q: For Legacy “S”… Is it no longer a requirement for the Job Folder to be yellow?
A: The job folder is not required to be yellow anymore. For the folks who still use the job folder, we would like them to continue to be yellow. It makes it a lot easier to find and differentiate.
Q: Are the building blocks going to be updated to absorb the additional costs for changes relating to the new TP.
A: This is not a TP question and needs to be answered by the Transport Build organization.
Q: If currently engineered or being installed before 4-1-8 the standard would be to the old TP. The supplier asked the question yesterday, to whom I do not know, and was told two different answers: one was yes, the other was no, if finished after 4-1-8 regardless of the job being engineered and installed prior to 4-1-8 the standard would be under the new TP.
A: The 1/1/08 version of TP76300 and TP76400 will be used on all jobs completing on or after 4/1/08. If the job completes prior to 4/1/08, the 3/31/07 version of TP76300 will be used.
Q: Once the training has been held internally by the supplier, according to the TP call yesterday the log was to go to the Area Manager or Regional SME. Is there one person to whom the log should go, sounds conflicting and confusing.
A: Send them to the Quality Assurance Area Manager for area you work in.
Q: I have a question on the updates, particularly Section 8 1.6.5 and 1.6.7. These two requirements don't seem to mesh as one says one thing and the second says another with respect to running cables directly on floor (1.6.5) and on racks (1.6.7). Can you clarify AT&T's position?
A: Section 8, par. 1.6.5 is for existing raised floor environments where the are no cable racks for transmission cables currently under the raised floor . Par. 1.6.7 is for any new raised floor applications. All the new cable routes will have cable racking.
Q: K3.4.12 - Midwest states training shall be yearly (Trompeter). Kings connectors in the south state that training should be carried out yearly. Who does the 3 year training apply to?
A: Except for the Midwest States, all of AT&T.
.
Q: L1.2.7.B Cables and wires less than 1/4" shall have a flag tag. Does this mean that every DS1 and DS3 wire must be tagged?
A: DS0 and DS1 = NO, DS3 = YES
Q: Although you have clearly mentioned that in an added or a new area, it is imperative that the vendor keep a record of all cable paths, etc. The only confusion that I encountered was when we make a new run going through an existing area (especially when the existing area looks like a spaghetti), how are we to create a path through the existing mess?
A: You make a new cable path up to the existing cable runs and then continue it on the other side. You are not expected to install cable racking through an existing mass of cables.
Q: Do the changes regarding K4.4.14 apply to all types of cables? (grounding, battery & battery return cables)
A: The changes to K4.4.14 apply only to battery and battery return cables. This requirement is under the "Power Connections" section of Section K. FYI, clear H-taps covers are required on H-taps used for grounding connections also per ATT-P-05405-E, Note 13. (Per Al Bergman, Common Systems Standards)
Q: Could you explain the addition of the Skill Level 4A or will it be detailed more in the training sessions?
A: A Skill Level 4A only does test and turn-up work on the equipment like the Tellabs Titan systems. They do not do any installation work at all.
Q: Section I, 2.6.5 seems to be saying that all new equipment frames installed will be 7' high seismic Zone 4 yet 2.6.7 refers to installing 7' low seismic frames. What is the requirement for our low seismic area, is a mix of the two types still acceptable as in the past? Are all frame extenders in our area, to 9' and 11'6", required to be high seismic also? We have quite a few various height low seismic frames and extenders in stock that will need to be used or junked depending on your answer.
A: Per TP76400, Section 6, par 6.1.3 and TP76300, Section I, par. 2.6.5, all new frames added in our central offices have to be Zone 4 type frames no matter where they are installed. Existing and new line-ups have to have Zone 4 frames installed.
Q: Do we have to label each individual fiber at the FOT end with a flag type label?
A: Yes, as long as they are larger than 900 microns.
Q: Do we have to have both near and far end information on the FOT Panel label?
A: Yes, if it is the flag type marker placed on the individual fiber conductors
No, not on the manufacturer supplied designation card, only the far end information.
Q: Where are we required to run OSP fiber tails in innerduct?
A: If is traditional OSP type fiber cable, it is required to be ran in innerduct anytime it is run inside the central office. Per O3.1a and Mike Yeilding
Q: Does AT&T Mobility fall under the TP’s now? I am still a little unclear as to where AT&T Mobility is fitting nationwide, if anywhere when it comes to the TP standards
A: Not currently at this time. They are still working on when they will start using TP76300.
Q: J3.3.13 - Battery return cables terminating on the battery return bus bar shall not be reduced. Does this requirement just cover the power plant return bar?
A: No, it also includes the return bus bar in BDFBs/SPDUs.
Q: Has the BDFB Load Demand Worksheet been updated by anyone to coincide with the new TP issue? Also, where can the Legacy T vendors find it.
A: The BDFB Load Demand Worksheet (LDW) has been updated. The latest version is Issue 4. It can be found on Woodduck under the Transport Build Table of Contents link. Legacy AT&T will not be utilizing the BDFB LDW because of their data bases that are currently utilized.
Q: Sec. N, - N2.3.3. Is this continuity check/test performed just on the original install of the bay and ESD jack or anytime work is performed in that bay or cabinet. What if no use of the jack is required, etc.
A: The continuity test for the ESD jack has to be tested only on the initial install of the bay.
Q: L2.1.2. - What about the 5ESS environment where the unit names and equipment numbers (PSU2-01) are not designated in the rear of the 5ESS cabinets. They are placed on the shelf bezel on the front Had a situation where we installed some misc. equipment in a M02 cabinet and we designated the front, but did not do the rear. The installer was not sure if he was required to do so and I wanted to make sure that we comply. I know that we must have a unit number if applicable or EQL location but the Name?
A: You do not need the rear designations on the main bays, LTPs, SMCs, etc., but in the Misc. bays, you do need them front and rear because the tech does work in the rear of those bays. The designations should read, Shelf-1, 2, 3, etc, Panel-1, 2, 3, etc, or Unit-1, 2, 3, etc.
Q: TP-76300 Sec G Para3.2.1 a states:
Complete the Negative Exposure Assessment (NEA) form (Figure G-3). The completed form
shall be maintained on-site until all drilling activities have been completed. Page 3 of the
completed form shall be sent or faxed to the NEA Management Center within two days of
completion of the drilling activities.
And later on per:
TP-76300 Sec G Para 3.2.1 m) iii states the following:
Fax a completed MDR to 512.250.2940.
What’s this for? This is the NEA vendor.
A: The NEA vendor maintains and checks the NEA training data base and verifies that the people listed on the NEA form are currently trained to perform the floor drilling. The MDR is for audit tracking to make sure we are disposing of the drilling debris as required.
Q: TP76400, Section, par. 2.1.1 - Equipment frames, as defined here, include relay racks, bays, and floor-supported cabinets comprised of a structural framework, and all equipment mounted thereon. All frameworks shall be designed and constructed for Zone 4 service when installed in AT&T equipment areas. Does this include battery stands?
A: No, Zone 4 requirements everywhere are only for electronic equipment frames. That includes unequal flanged frames, network bay frames, data cabinets used to house equipment shelves. Battery stands do not need to be Zone 4 when the battery string is installed in low seismic risk locations. However, there are requirements that all battery stands shall be anchored to the building floor and that they have side and end rails in all locations no matter the seismic risk. The only difference is that heavier duty anchors are used in higher risk locations and lighter duty anchors in low seismic risk locations. Jeff Stroman in Bill Price's groups maintains the list of approved battery stands for all zones.
Q: 6.1.3 - Low seismic risk requirements have incorporated minimum equipment securing measures required for all sites to reduce risks for equipment overturning or equipment walking due to building vibration, accidental impacts, unbalanced loads or other physical mishaps. All network equipment frames and DC power equipment including battery stands shall always be secured to building floor in all locations. Battery stands shall be equipped with side and end rails around all jars in all locations in accordance to DC power section of this document. Do round cell stands with lock wedges meet this requirement?
A: Per Larry Wong: The locking wedges and the curved rear panel of the Tyco composite battery stand replaces side and end rails of a conventional stand.
3/28/08
Q: On the fiber jumpers' that are internal to the 5ESS switch, do these require flag labels on both ends?
A: Per Mike Yeilding, the fibers internal to the switch do not require the flag markers.
Q: Can everything can be listed on one (1) MDR other than removed equipment including the bag of drilling debris. The TP does not say anything about separate MDR's.
A: No, the drilling debris is not a tangible item and is not being turned over to AT&T. The floor drilling debris needs to be on a separate MDR.
Q: K4.4.10. Barrel taps? Yes Are you still looking for these? Yes Appears that we are getting clear H-taps rather than barrel taps. There is no such thing as a clear H-tap. There is a clear H-tap cover. I thought that this was the, preference-barrel taps.
A: The in-line reduction (barrel) taps are required to be used instead of H-taps. If for some reason there is no size available in the in-line reduction tap, then an H-tap can be used, but only if there is no size available or if the application requires an H-tap (transitions). If you have to use an H-tap, then a clear H-tap cover is required.
Q: L2.2.3. AT&T installers had questions regarding this and more than anything as to where and exactly how the information is to be listed. Such equipment as the new DMX equipment, etc.
A: If you add equipment or cabling into a transport type of bay, then a designation showing the far end terminations of the added cabling is required. It can be on the shelf itself, or on the bay upright. For example, adding DSX-1 or DSX-3 cabling. You designate it tomorrow as you do today. If it is a switch bay, then this requirement is not applicable.
Q: F2.1.16. If the panned rack is to end just at the opening of the penetration and pick up on the other side. It then says to secure the cable to the nearest strap on the cable rack. Are you just referring to the straps that run through the cable hole, because as I see it all the straps on the outside of the hole will be covered up with the pan.
A: Correct, just the straps through the cable hole if the panning stops just before the hole.
Q: Also, will need to take the pan to the last strap so it can be properly taped so it does not hang loose or fall through?
A: Correct
Q: Will the JSA be required for engine alternator, PM340 and fuel monitor power monitor installations?
A: If you are not using the JSA today for any of your jobs, per D2.0.1, it is not required to be used tomorrow.
Q: Would a Critical MOP be required any time the utility power to the office is interrupted?
A: Per D4.1.1e, a Critical Power MOP is required.
Q: The MOP is quite different than the version in EJF: my question is do we use the TP version or do we continue to use the MOP form in EJF and as always upload the Volatile Work Power MOP plus added will be the ASK YOURSELF SECTION for any volatile work and the Dry Run Walkthrough for Critical Power Work?
A: Continue to use your current processes until told to do otherwise. Use the EJF version.
Q: Does the AFL Quality Audit have to be uploaded to EJF?
A: Continue to use your current processes until told to do otherwise. Yes if that is what you do today
Q: Will the current forms in EJF be replaced with the forms listed in the TP 76300? If yes, will all required forms be added to the EJF database? Are all forms listed in the TP 76300 required in BellSouth? If no, will BellSouth provide a list of required forms?
A: The Installation Supplier shall use the current version of all forms, unless AT&T authorizes the use of surplus stock forms.
Q: Is the current BellSouth Quality Checklist acceptable to meet this requirement?
A: The Installation Supplier shall consider the job complete when all items described below have been complied with: An Installation Supplier quality performance audit of the installation has been completed; results of the audit documented in the job folder, and documentation that all defects and/or discrepancies have been corrected. This includes when the defect was corrected and who corrected the defect. A check list is not an audit.
Q: What are drop in ceiling plates and why would a label not be required?
A: Drop in ceiling plates are the 3M plates you drop down into the cable hole that is supported by either stirrups or a ledge made by a modified steel cover plate.
Q: Where does the vendor acquire the cable hole labels?
A: The labels are procured through Wallace. See ordering information below.

Q: Section F, Par. 5, Labels, Does this stand?
A: Yes, use the labels identified in TP76300 and the color scheme.
Q: Section F, if we meet the requirements for the UL instructions per System will we be OK?
A: Per Section F, 2.1.3, you are required to close the cable hole per the UL certified fire stop system drawings.
Q: Are non-metallic pans allowed or not? If not there is nothing in the TP76400 that states they are not.
A: On new jobs, they are not allowed. If it a current on going job where they have already been ordered and installed, then they are allowed.
Q: What about an 11' environment with bay extenders, do we need an 11' end guard?
A: Per I2.6.21, yes, you need an 11’-6” end guard.
Q: Should DESP stop retrofitting cable holes with QWIK connect unless specified in BER?
A: Yes, Per Larry Wong, the DESP should stop retrofitting the holes to QWIK connect.
Q: When we use the Z frame as we do on all our Wall Holes you Cannot turn Bricks the 8 inch deep direction because a 1 inch turned UP lip on the entire perimeter edge of the Z Frame will cut into the Block plus the W-L Drawing for Hilti Wall Holes shows Z Frame System with Blocks at the 5 inch depth only required to meet the UL requirements for all wall Holes. Cost to turn Hilti Blocks 8 inches deep through Walls which are not required per UL standards will greatly increase per block count per hole.
A: Per Section F, 4.14.1d states that the fire block will equal the wall thickness. If the wall is 5 inches and the Z-frame is 5 inches, then the blocks will be installed in the 5 inch direction.
Q: Are metallic cable rack pans the preferred method for all future installations in BellSouth?
A: Yes, you should not install non-metallic cable rack panning on future jobs.
Q: End panels or end shields shall be installed on all frame uprights not adjacent to another frame or a building obstruction. Is this the preferred method for all future installations in BellSouth?
A: Yes
Q: If OEM equipment provided does not meet TP standards is a waiver required? EX – Gray bay extender strap with black heat shrink covering crimp on ground.
A: No, the OEM equipment and the way it is assembled at the factory is not audited and does not need a waiver. Only the work the installer performs on site is audited.
Q: Is the switchboard cable rack required to be stenciled switchboard cable only when two tier cable rack is installed?
A: No, in L2.1.8, it specifically states “… except switching equipment cable racks, shall be designated”. This includes switchboard cable racking.
Q: Can the power assignments be affixed to the front of the power source (fuse panel, etc.)?
A: Yes, as long as it is at the top and front of the bay.
Q: Do we put an End Guard on all bays in a lineup that stands alone such as in a lineup with 10 bays and bays 1, 3, 6, 8, and 10 exists do we install 10 end guard panels per TP’s instructions.
A: Yes, but you can place an end panel, an end shield or an end guard on these stand alone bays. One of the 3 are required.
Q: Do we add the full end guard because our existing practice is the end guard covers equipment 7’ area only and not the extension? Also do we do this for existing equipment or future equipment we add?
A: Yes, you add full height end guards, panels or shields. You do this for any newly added frames on jobs completing 4/1/08 or later.
Q: I1.3.9 states Switchboard and power cables installed on vertical cable racks shall be limited so that the cable is not closer than 3 inches from the side of the cable hole. I4.1.2 states a cable hole shall not be filled beyond 75 percent of its capacity, and cables shall not be placed closer than 3 inches from edges. Does this mean to include all edges top and bottom of a wall hole and all 4 sides of a floor hole?
A: This includes only the side and front edge of the cable hole. The cables are required to be pressed up against the back edge of the cable hole with putty between the cables and the edge of the hole for smoke stopping purposes.
Q: How will diversity requirements be applied to existing office conditions? Will the Models be updated by 4/1/2008 to accommodate diversity?
A: The requirements are written for existing office conditions. If there are no separate racks to run the cables diversely, then use the opposite side of 1 rack, etc. See the sub-paragraphs of the requirement.
Q: This condition, blocked cable paths, cannot be avoided in some offices due to equipment locations and existing congestion conditions. Is a waiver request the proper approach? Can a blanket waiver be issued for a particular office where this condition is unavoidable?
A: An approved JIM is required prior to deviating from the TP requirements. The engineer needs to sign a JIM for each office and job to allow for the deviation. Blanket waivers are discouraged, but there is nothing in TP76300 that states that a blanket waiver cannot be approved by the engineer.
Q: Was this an over sight or is the use of PVC tubing and strips prohibited for cable protection?
A: Formed fiber tubing and formed fiber edging is still allowable. I believe this is what you are call PVC tubing and strips.
Q: Are there limiting situations when power cable is authorized to drop through a cable rack?
A: Yes, you do not want to block future runs of power cables.
Q: Battery return cables terminating on the battery return bus bar shall not be reduced.
Does this apply only to both internal and external BDFB bus bars?
A: Yes
Q: Verification of a locking-type washer shall be by visual inspection. Refer to Figure K-1. Is it talking about not putting no-ox on the painted surface or the entire connector?
A: It is doing both. It is giving an example of how a single hole lug should be secured.
Q: In-line reduction (barrel) taps shall be used in preference to H-taps where possible to reduce cable build-up on the cable racks. Is this the preferred method for all future installations in BellSouth?
A: Yes, it is.
Q: Power leads shall not be stacked. Does this apply to DSX lamp leads that are multipled from panel to panel?
A: Yes it does. Each DSX panel has it’s own power coming from the miscellaneous fuse panel in the DSX bay.
Q: Says that the vendor can stack back to back Return Leads from a Single Network Bay on the External Return Bar. We have never done this because if you remove this group of leads by mistake for any reason you will drop the entire bay if both A and B loads are stacked?
A: Now you are allowed to do it.
Q: L2.1.9, Year/TEO Number/Vendor Name designation. Does this mean you still have to put a vendor label with the vendor name?
A: No, you still do not have to put a vendor label with the vendor name. L2.1.9 cover it.
Q: Stamping shall be accomplished using a rubber stamp of the appropriate size. Is a permanent marker and stencil guide an acceptable alternative to rubber stamping?
A: No, it is not. The use of a lettering guide is allowed in a few specific areas
Q: All stamped lettering and numbering shall be coated with clear shellac. Is this the preferred method for all future installations in BellSouth?
A: It is not a preferred method, it is a requirement. If you stamp your designation, rather than use P-touch labels, you coat it with shellac.
Q: The use of thermal transfer technology tape systems is limited to applications on smooth, nonporous surfaces. This tape shall not be used on ripple-finished surfaces or any other irregular surfaces. Are P-Touch, Brother, Brandy label machines considered “thermal transfer technology” type labelers?
A: Yes, that is exactly what they are referring to.
Q: When communication panels are to be added, which are to be multiplied to an existing panel, the multiple destinations shall be designated on the rear of both the new and existing panels. Get Clarification
A: If you multiple comm panels, you need a designation identifying the far end terminations of the multiples on both panels.
Q: Front and rear of equip positions designate with name and number. What is meant by name? (Ex: DSX 3 panel – Do you want DSX 3 PNL # stenciled on the back or CLEI and PNL #)
A: Shelf 1, Panel 1, Unit 2.
Q: Where are power source labels placed on a miscellaneous bay when shelves are fed from different power sources?
A: This requirement is only when the power source is feeding a fuse panel in the bay, not a shelf.
Q: Says that all stamping shall be coated with a thin layer of Shellac. Should this read a thin layer of non-toxic clear glue?
A: The question of the use of “shellac” was taken back to the committee and they agreed to keep this wording
Q: Gives direction on Cable Hole Designation where the actual cable hole number has to be stamped on the hole frame or cover. Since wall holes have no cover per Hilti system should the VENDOR mark these holes with a plate and can we get the OK do it this way and where would we get the plate?
A: If there is no cover plate, then you do not have to follow this particular requirement. There is a requirement to place the cable hole designation on the wall also. Follow this one. You do not need to add a plate just to put on a designation.
Q: L2.4.4g, BDFB’s shall be designated from bottom left panel up to top right panel is this for Top fed or Bottom fed BDFB’s or is it for both Top and Bottom fed. Also should it be 1-20, 21-40, 41- 60 or 1-20, 1-20 and 1-20 fuse positions?
A: This is for both top and bottom fed BDFBs. No, it should be 1.1, 1.2, 1.3……..1.20, then 2.1, 2.2, 2.3…….2.20. Fuse panel and fuse position number, just like the requirement states.
Q: M1.4.11, Does this mean that if the fuse connection stud can take a # 2/0AWG then that is what we have to place in the BDFB?
A: #2AWG is the largest size cable that can be placed in the BDFB at the fuse position. If the cable is larger than #2AWG, then it has to be reduced down using in-line reduction taps. A 2/0 size cable is way too big.
Q: Limits patch cords to simplex and duplex only unless otherwise specified by an equipment drawing. SEC O par 1.2.1.2 interconnect cables (commonly referred to as a jumper or patch cord) consist of one, tow or four fibers. SEC O 4.1.2 requires patch cords to be run in FPS. Some current models specify using octal fibers. Can a quad or octal patch cord be run in the FPS?
A: Yes, if required to be used, a quad or octal patch cord can be run in FPS.
Q: Switchboard-type cable shall be cut initially as close to the termination of the cable at the equipment or frame as possible and mined toward its source. Are these type terminations no longer required to be physically disconnected prior to cutting the cable.
A: If the local techs want you to remove the connection prior to cutting, then that is OK also. They are not required to be removed prior to cutting.
Q: Where do vendors get the "approved" red BITS timing books?
A: From their suppliers.
Q: All flexible metallic conduits shall have a #6 AWG continuity bond across the flex section. This is listed in the section above that pertains to the exhaust system. Does this mean that our welded continuous stainless steel flex section requires an additional #6 bonding across each flex section?
A: Yes it does.
Q: The standby engine/alternator set control cabinet shall have an #6 AWG ground lead terminated with a two-hole crimped lug and be tagged. Is this going to be required for engine mounted DEC550, DEC340 and DEC3 controllers? This additional ground is not being installed at this time in TN and KY.
A: Yes it does.
Q: Any radiator not located on the engine/alternator skid shall comply with all ‘remote’ radiator requirements. What are these requirements and where is this documentation located?
A: The are located in BSP 790-100-658MP, Standard Specification and Performance Requirements for Engine/Alternator Sets.
Q: The emergency shutdown switch for the engine shall be designated and covered to prevent accidental activation. Does this apply to the emergency stop installed by Kohler on the controller or is this for additional remote emergency stops added?
A: It is for all emergency stops installed.
Q: There is no exception for grounding timing leads of DDM-2000 & FT 2000 in TP 76300 or TP 76400. Ground is hard wired in hooded connector at equipment end. Do we need a waiver when we add one of these shelves?
A: If the interconnect drawing shows that both ends of the timing ground leads are to be terminated, then they have to be terminated. A waiver is not required because the drawings take precedence over TP76300.
Q: Are local (audible and visual) office alarms required?
A: That is up to the local LFO and maintenance folks. It is different in different locations.
Q: How do we access the Ask Yourself Training on-line?
A:
Q: There is reference to a paper job folder in the TPs,
a)How does this accordion style folder mesh with EJF, or does EJF entirely take the place of this folder?
b)If the folder is required, does it duplicate the documents that are in EJF, or would it only contain items like a copy of the dated and initialed MOP and marked prints?
c) If the folder is required, are there additional requirements for it other than the size? (ie color etc.)
d) The example of a label on this folder shows an AT&T logo. Isn’t this logo proprietary? How or would the vendor be expected to replicate this exact label with the AT&T logo, would AT&T supply the logo, or would the AT&T logo even be required?
A: The job folder and label are not applicable in the Legacy Bell South area. Continue using the EJF as before.
Q: There is a reference to a standby engine under the critical power MOP section.
a) When would a MOP for an engine be considered as critical?
b) Would the AT&T Rep need to be for every step of an engine installation or only a certain portion of the installation?
A: Refer to Section D, par. 4.1e of TP76300. a) All the time, b) The AT&T Rep would be needed on every step as he/she is identified on the MOP.
Q: To whom in the Quality organization is the monthly Excel report detailing jobs completed in the previous month to be emailed to? (Can we assume that this based on the completion date for the job as opposed to the final drawing completion date?)
A: Follow the current process for reporting completed jobs via EJF.
Q: How can I get a copy of the BSP790-100-658MP drawing referenced in section U of TP-76300?
A: Via the Common Systems Extranet web site.
Q: Would a JIM be completed and emailed to the AT&T rep for all email communication between the vendor and the PCM or other AT&T rep?
A: Yes, or you can fax it.
Q: The Excel spec form states AT&T Power Engineer signature. Does this mean that this spec needs to be emailed to the AT&T PCM, signed, scanned back, and then added to EJF to be in compliance with the TP as opposed to the current method of just adding a copy of the spec as an attachment?
A: Follow current procedures
Q: What is the process for miscellaneous work operations such as warranty work, defect correction, etc.? (ie anything that does not specifically have a TEO to perform the work)
A: There is no difference in process. Follow the same process.
Q: What are the necessary environmental standby engine permits referenced in TP-76300 section 3.1.4?
A: These are permits that are required based on your locality and municipality.
Q: What is the Installer card expected to look like? Could we see an example?
Engines were listed under Power, so would an installer card for an engine vendor read something like Tier 1 Power (engine vendor) Level 4 Installer’s name plus company name.
Should this installer card include a photo ID?
A: You need both your company’s photo ID and the AT&T contractor’s photo ID. The installer information can be on a separate card or placed on the back of either photo ID. It should state something like: “Level 4 – Power”
Q: TP 76400 SEC 5 Par 2.2.13 list as the only exceptions for not adding ESD jacks as power distribution racks / bays and to equipment racks that have no accessible space on which to install an ESD jack. Are ESD jacks required on DSX1, DSX3 and LGX bays?
A: Per TP76400, yes they are required on those bays.
Q: TP 76300 Sec J Par 1.3.9 cable on vertical cable rack shall be limited so that no cable is closer than 3 inches from the side of cable hole. SEC J Par 4.1.2 specifies a cable hole shall not be filled beyond 75 percent of its capacity, and cables shall not be placed closer than 3 inches from edges. In most cases in the Southeast vertical cable rack is terminated at cable holes per ATT TP 76409 Fig 9D and cables are within 3” of the rear of the cable hole.
Do the TP references above apply to the rear of the cable hole?
A: No, they do not apply to the rear of the cable hole. In fact, the cables should be up against the cable hole with putty between the cables and the hole to keep air from coming up the rear. The 3 inch rule is the sides and the front of the cable hole.
Q: TP 76400 SEC 11 Par 2.3.3 All timing signal leads from the BITS clock OUTPUT ports to network elements shall be run using approved 1175A red jacketed shielded cable. The only exception to this is the allowance of the use of the gray jacketed 1175A cable in legacy AT&T applications because the red color is used exclusively with power cables. The shield/drain wire shall be DC/hard grounded at the clock end only. The shield/drain wire shall NOT be DC/hard grounded at the Network Element.
1. Some equipment comes with hooded connectors for timing and is hard grounded at the equipment end within the connector. (ex: DDM2000, FT2000). Is a waiver required when installing this equipment?
2. Cable assemblies for the above equipment is ordered from manufacturers drawings and the cables that have been provided are not red jacketed. Is a waiver required when installing these cable assemblies?
A: If the AT&T drawing shows that the ground lead is to be terminated at the network element end as well as the BITS clock end, then no, a waiver is not required. The AT&T drawings take precedence.
If the manufacturer and AT&T drawings show a gray/slate color for the timing cable, then no, a waiver is not required.
Q: Is fuse size/amperage required on the ‘Power Source’ label (Figure L-10) on the network end? The vendors have always done it, but frankly, I can’t find a standard that ever did require this information.
A: No, it is not required on this designation. The fuse size will be designated at the source location.
Q: Referencing L.1.4.9, …DC power source label at the top front of the bay.
Can the power assignments be affixed to the front of the power source (fuse panel, etc.)?
A: Yes it can as long as it is at the top and front of the bay. The requirement states that the designation has to be at the top of the bay, not where at the top of the bay.
Q: 2.1.1 - Equipment frames, as defined here, include relay racks, bays, and floor-supported cabinets comprised of a structural framework, and all equipment mounted thereon. All frameworks shall be designed and constructed for Zone 4 service when installed in AT&T equipment areas. Does this include battery stands?
A: No, Zone 4 requirements everywhere are only for electronic equipment frames. That includes unequal flanged frames, network bay frames, data cabinets used to house equipment shelves. Battery stands do not need to be Zone 4 when the battery string is installed in low seismic risk locations. However, there are requirements that all battery stands shall be anchored to the building floor and that they have side and end rails in all locations no matter the seismic risk. The only difference is that heavier duty anchors are used in higher risk locations and lighter duty anchors in low seismic risk locations. Jeff Stroman in Bill Price's groups maintains the list of approved battery stands for all zones.
Q: Low seismic risk requirements have incorporated minimum equipment securing measures required for all sites to reduce risks for equipment overturning or equipment walking due to building vibration, accidental impacts, unbalanced loads or other physical mishaps. All network equipment frames and DC power equipment including battery stands shall always be secured to building floor in all locations. Battery stands shall be equipped with side and end rails around all jars in all locations in accordance to DC power section of this document.
Do round cell stands with lock wedges meet this requirement?
A: Per Larry Wong: The locking wedges and the curved rear panel of the Tyco composite battery stand replaces side and end rails of a conventional stand.
Q: TP-76300 Sec G Para3.2.1 a states:
Complete the Negative Exposure Assessment (NEA) form (Figure G-3). The completed form
shall be maintained on-site until all drilling activities have been completed. Page 3 of the
completed form shall be sent or faxed to the NEA Management Center within two days of
completion of the drilling activities.
And later on per:
TP-76300 Sec G Para 3.2.1 m) iii states the following:
Fax a completed MDR to 512.250.2940.
What’s this for? This is the NEA vendor.
A: The NEA vendor needs the MDR to track disposition of floor drilling debris per the NEA process requirements.
Q: Section D, 3.2.1 Does the CO Manager determine the "Maintenance Window by the type of equipment to be worked on?
A: Yes, the CO Manager determines the "Maintenance Window" for their offices.
Q: Section E - Is the project number still required on the NEA form?
A: Yes, if the project number field is on a form, the project number should be populated.
Q: Section L, 1.2.9b - Are flag labels required on the following: CAT5's, Dantel, shelf grounds, alarm or P10 loops with in the bay .
A: Interbay cables and wires ................
