Channelized T1/E1 PRI Network Modules with G.703
CT1/PRI and CT1/PRI-CSU modules receive and transmit data bidirectionally, at the T1 rate of
1.544 Mbps.
Channelized T1/E1 PRI Network Modules with G.703
This section provides information about the following network modules:
•
•
Cisco T1/E1 channelized PRI network modules with G.703 provide connection of one or two primary
rate ISDN lines. T1 or E1 interfaces are configurable through Cisco IOS command-line interface (CLI)
commands. Each port supports 100/120-ohm balanced and 75-ohm unbalanced termination, and features
RJ-48C connectors and cable accessories allowing for DB-15, BNC, and other connector types. An
onboard advanced integration module (AIM) connector allows for future universal port AIM support.
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
Caution
connect the 1-port T1/E1 channelized PRI network modules with G.703 (NM-1CE1T1-PRI) and 2-port
T1/E1 channelized PRI network modules with G.703 (NM-2CE1T1-PRI) only to intrabuilding or
nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded
at both ends.
Cisco T1/E1 channelized PRI network modules with G.703 (NM-1CE1T1-PRI and NM-2CE1T1-PRI)
