Connecting Channelized T1/E1 PRI Network Modules with G.703 to a Network

Warning For connections outside the building where the equipment is installed, the following ports must be connected through an approved network termination unit with integral circuit protection: T1 Statement 1044

Figure 4 shows a connection between a channelized T1/E1 PRI network module with G.703 and a networking device.

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.
