DSL Interface Cards
Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the HWIC-2SHDSL and HWIC-4SHDSL interface cards only to intra-building or unexposed
wiring or cable. 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, Issue 4) 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.

Caution Inserting an RJ-11 connector into the Cisco HWIC-4SHDSL port may deform pins 1 and 8, which may
prevent solid contact between the connector and the plug in subsequent connections. If solid contact is
prevented, line -1 tip and line -3 ring will not work properly.
