Analog Direct Inward Dial (DID) Interface Cards
A Direct Inward Dial (DID) voice interface provides DID service to extensions on a PBX.
Figure 94
shows the VIC-2DID card, and
Figure 95
shows the VIC-4FXS/DID card.
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.
Note
Each port on the 4-port FXS/DID VIC can be configured as either Foreign Exchange Station (FXS) or
Direct Inward Dial (DID) when it is used with phones with a Ringer Equivalence Number (REN) load
of 1 or less.
If the REN load on any port is greater than 1, all four ports must be configured as either FXS or DID.
For information about using FXS with the 4-port FXS/DID VIC, see the
“Foreign Exchange Station
(FXS) Interface Cards” section on page 3
.
Note
Cisco 2600XM series, Cisco 2691, Cisco 2800 series, Cisco 3600 series, Cisco 3700 series, and
Cisco 3800 series routers support DID on the 4-port FXS/DID cards in Cisco IOS Release 12.3(14)T and
later.
