Cisco ASR 903 Installation Guide

To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect
the T1/E1 ports only to intra-building or unexposed wiring or cable. The intrabuilding cable must be shielded
and the shield must be grounded at both ends. The intra-building port(s) of the equipment or subassembly
must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are
designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE)
and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient
protection in order to connect these interfaces metallically to OSP wiring.
