On the Cisco 2801, 2811, 2821, 2851, 3825, and 3845 voice platforms, one or more PVDM2 DSP
cards are needed to support VIC and VWICs if they are installed on the chasis WIC slots, or voice
orts may be missing in the running configuration. The PVDM2 DSP cards hold DSPs that make the
VICs fully functional, and are installed on the motherboard of these ISR platforms. If VICs and
VWICs are installed in a Network Module, the Module itself must have some DSPs.

The VIC-2DID card can operate in both DID (default setting) and FXS modes on the Cisco 2801.
DID mode is supported from IOS 12.3(8)T4 onwards, while FXS mode is supported in IOS 12.3(11)
T onwards. On other ISR platforms, the VIC-2DID card only operates in DID mode until the IOS
12.4(3) release where both DID and FXS modes are supported.

The VIC-4FXS/DID card can operate in both FXS (default setting) and DID modes on the Cisco
2801. On other ISR platforms, the VIC-4FXS/DID card only operates in FXS mode until the IOS
12.3(14)T release where both modes of operation are available for the VIC-4FXS/DID card on the
Cisco 2811, 2821, 2851, 3825, and 3845 ISR platforms.
Pinout Information
Port zero on the VIC-2FXS card is designed to accommodate a United States style two-line phone,
instead of the usual European style one-line phone.
This means that in addition to pins three and four in use, pins two and five are also monitored. In
some handsets it is possible that pins two and five are wired up to allow last-number recall or call-
forwarding. If this is the case, port zero on the VIC assumes you have a two-line phone, and port 1 is
shutdown.
In order to check this, use only two wires in the cable from the VIC to the phone and verify that port
1 becomes active again.
