(Pages 5-7 of Form 3c) for your records and forward the original to AT&T
National Technical Marketing (NTM).
NTM also evaluates the complexity of the facility configuration requested.
Examples of complex configurations are connections into PBX networking
applications, connections to multiplexing arrangements, or applications that
involve customer engineering or design.
If an order is considered complex, NTM directs you to the Business
Communications System (BCS) National Engineering Center (NEC).
If NTM notifies you that the order's configuration is not complex, Tier Ill
General Business System (GBS) National Technical Service Center (NTSC) is
authorized to approve the configuration.
The NTSC group's pre-authorization review is based, in part, on information you
provide to them. Specifically, you must send them
a
copy of the planner (pages 5 through 7 of Form 3c)
a completed 'Non-Complex Configuration' sheet (pages 9 through 11 of
Form 3c) for each 100D module you plan to install
