Connecting an Analog DID Interface Card
Use a standard straight-through RJ-11 modular telephone cable to connect the VIC-2DID or
VIC-4FXS/DID interface card to a PSTN or PBX.
Step 1
Install the grounding lug on the router. See the hardware installation guide for your router for detailed
instructions. (Grounding on the Cisco 1700 series routers is done on the router chassis, and does not need
a grounding lug.)
Caution
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the 4-port FXS/DID card (VIC-4FXS/DID) only to intra-building or non-exposed wiring or
cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.
Step 2
Confirm that the router is still turned off.
Step 3
Connect one end of the straight-through RJ-11 cable to an RJ-11 port on the card. (See
Figure 96
.)

Caution
The VIC-2DID or the VIC-4FXS/DID interface cards may be damaged if connected to a standard PSTN
line. Ensure that lines to the PSTN are provisioned for DID.
