Preparing for Installation of the Cisco Unified
Videoconferencing 3522 BRI Gateway
The Cisco Unified Videoconferencing 3522 BRI Gateway prepares the signaling for outbound
videoconference calls that are transmitted over Integrated Services Digital Network (ISDN) networks.
For videoconference information to arrive at its destination, you must work with the BRI service
provider to ensure that the gateway and the ISDN service are compatible. You must gather information
about the service provider equipment and provide the service provider with information about the
gateway.
Before you order BRI service or connect the Cisco Unified Videoconferencing 3522 BRI Gateway to
your existing BRI service, we suggest that you gather the following information.
Step 1 Identify the ISDN provider you want to use as your Local Exchange Carrier (LEC) for local calls.
Note The LEC is the local telephone company that provides ISDN services for your local calling area
and to which your equipment connects.
Step 2 Identify the ISDN provider you want to use as your Interexchange Carrier (IEC) for long-distance calls.
Note The IEC and the LEC are different companies. Often the LEC will contact the IEC and provision
long-distance service for you. Verify that your LEC performs this task, and contact an IEC if the
LEC does not.
Step 3 Determine how many BRI lines you want to connect to the gateway.
Step 4 Identify the ISDN equipment or signaling format your LEC uses.
Step 5 Determine whether you want to use layer 1 line hunting.
Step 6 Have your ISDN service provider turn off the following switch settings:
• Packet Mode Data on the D channel
• Terminal Display Text
• EKTS
• Call Appearances
