Connecting Video Dialing
Module
If your Cisco MC3810 has a video dialing module
(VDM), connect the VDM port and one of the
Cisco MC3810 serial ports to the video codec.
For the dialing interface, use an RS-366 cable with
one 26-pin connector and one DB-25 connector
(included with VDM).
For the video data connection, use a Cisco V.35 DCE
serial transition cable with ringing indicator (RI)
(included with VDM).
Note: For video conferencing, you must also set up
a WAN connection through the T1/E1 trunk port.
See the "Connecting the T1/E1 Trunk Port to the
Network" section on page 5.
