Standard Operating Procedure for all Work Scopes Upon arrival to site location, before entering the site compound or opening any equipment, call the NFSD AND C4E to Status the full site for any alarms and log them. If any are Service Impacting Alarms, call your supervisor immediately and do not enter the location until you are directed to so by B&V. 781-236-3500 Non-Service affecting MOPs must be submitted for all work performed unless the work is service affecting i.e. antenna swaps, DC converter installations; in which case a service affecting MOP must be submitted 48 hours in advance and approved. Contact Sarah Fucci for all MOPs. FucciSE@bv.com 913-458-1804 201-417-0571 (cell) **IMPORTANT** An alarm check must be called in after completion of any work taking place in the Power Plant and Telco Box to ensure the site is alarm free and taking calls even if crews are still present performing work. **IMPORTANT** Antenna swaps to the existing system (GSM/UMTS) must be reported to the FCM assigned to the site the day of the swap. B&V will notify AT&T to monitor the site performance. If the site is negatively impacted the GC is required to remobilize immediately to trouble shoot.

MOP flow and Process

Prior to visiting an AT&T cell site, Contractors performing any Service Affecting / Impacting or Non-Service Affecting / Impacting scopes of work are required to have an approved AT&T Method of Procedure (MOP) number.

All MOPs need to be submitted a minimum of 48 hours prior to the work commencing. The AT&T Market Managers need this time to review for conflicts and other issues. We have to be conscientious of this time line so that we have a manageable work flow.

MOP dates should not overlap. Check the latest version of Swifttrac to see what MOPs are already open for each site. Duplicate or overlapping dates on your requests will cause delays. If you need to be added to the Swifttrac distribution list please let you B&V point of contact know and we will submit that request.

Once on an AT&T cell site – but prior to performing any work, All Sub-Contractors must also call into the AT&T's National Field Support Desk (NFSD) for all scopes of work. If the Sub-Contractor is performing SERVICE affecting / impacting scopes of work they will then be directed to call the NFSD with a provided equipment in maintenance (EIM) number correlating to a network impacting event.

The NFSD operates 24/7 (except for Sunday maintenance window) and can be contacted by calling 1-866-539-1483.

Once work at an AT&T cell site has been completed, all Contractors must contact the NFSD to confirm site operations have been restored to their original condition or better. (This means that the Contractor must resolve any alarms or request assistance to resolve any alarms.)

Should ALU have an issue during Integration you may be requested to mobilize and get a crew out to the site

ASAP. These sites may qualify for an emergency MOP, so you can address the issue the same day you get

notified.

For Pre Integration Alarms (614-718-6400 opt #1) you will need to contact the ALU RITC to troubleshoot with.

They will handle all issues that have prevented the site from getting integrated and any external alarm testing.

RITC will perform RF tests to ensure RRH are working correctly. If external alarm testing is requested you will

need to test out ALL external alarms on site to get them closed out. You MUST have the RITC engineer issue an

internal completion report to his team, if not another site visit will be needed to retest the alarms.

For Post Integration Alarms (614-718-6400 opt#2) you will need to contact the ALU OSC. They will be able to

run RF tests and assist you in high level troubleshooting the site.

Please make sure that your crew is making notes on whom they speak to at ALU and they should be taking pre

and post photos with each visit.

Standard Requirements for all Work Scopes All work must be in compliance with AT&T’s ND-51 audit form. Pre Construction Photos Take site photos prior to performing any work. Document the existing condition and document the post construction condition. These photos may be used to determine responsibility should the site be negatively impacted. i.e. open cabinets, broken locks, garbage left behind, roof damage etc. -Report damages, theft and any other pertinent issues immediately to your FCM. Labeling Refer to AT&T’s document LTE Guidelines CTO 1475 REV 2.0 *Note the inconsistency on page 22 where C-2 & A2 land in the squid; C-2 & A-2 should actually be swapped in the documentation.
