Channelized T1/E1 PRI Network Modules with G.703 Chapter 7 Connecting ISDN PRI Network Modules 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: • 1-port T1/E1 channelized PRI network module with G.703 (NM-1CE1T1-PRI) (see Figure 7-1) • 2-port T1/E1 channelized PRI network module with G.703 (NM-2CE1T1-PRI) (see Figure 7-2) 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. Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, 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) replace the following network modules (also described in this chapter): • NM-1CE1B • NM-1CE1U • NM-1CT1 • NM-1CT1-CSU • NM-2CE1B • NM-2CE1U • NM-2CT1 • NM-2CT1-CSU For information on Cisco modular access routers supporting Cisco channelized T1/E1 PRI network modules with G.703, see Table 7-1.
