Preparing for Installation of the Cisco IPVC 3521 BRI Gateway
The Cisco IPVC 3521 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 IPVC 3521 BRI Gateway to your existing BRI
service, we suggest that you gather the following information.
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.
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.
3.
Determine how many BRI lines you want to connect to the gateway.
4.
Identify the ISDN equipment or signaling format your LEC uses.
5.
Determine whether you want to use layer 1 line hunting.
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
•
Key Hold
•
ACO
