800 Co-Bri Module - AT&T MERLIN LEGEND Reference

Also at the time of subscription, the type of terminal configuration, in this case
Type D, is specified. Although the 5ESS Generic 8 Custom (5E8) software
supports two types of services over BRI lines (Point-to-Point and Point-to-
Multipoint), the MERLIN LEGEND system only supports Point-to-Multipoint.

800 CO-BRI Module

The 800 CO-BRI (Central Office-Basic Rate Interface) module is the MERLIN
LEGEND system interface to BRI lines from the central office. At least one 800
CO-BRI module must be in the system for the system to be connected to BRI
lines. Up to five 800 CO-BRI modules can be placed in a system (or any
combination of line modules up to the system maximum of 80 lines).
Because of limitations with the 391A, 391A 1, and 39IA2 power supplies,
the number of 800 CO-BRI modules plus 100D modules cannot exceed
three per carrier.
Each 800 CO-BRI module has eight ports; each port supports two MERLIN
LEGEND lines, for a total of 16 lines per module (see Figure 1-3).
