Configuring the Quad BRI network interface

© Polycom, Inc.
The VSX system supports the Quad BRI network interface for ISDN calling.
You can set up the ISDN Network option only if the system has an ISDN network
interface module installed. The system detects the ISDN interface and displays
only the required configuration options.
1. Go to System > Admin Settings > Video Network > ISDN Network.
2. Configure these ISDN BRI Protocol settings:
Setting Description
Enable ISDN H.320 Allows this system to make H.320 (ISDN) calls.
Number of ISDN Specifies how many channels to dial at one time.
Channels to Dial in
You can specify up to 8 channels. If you experience network
Parallel
problems, decrease the number.
ISDN Switch Specifies the protocol used by your network's switch.
Protocols
Outside Line Specifies the ISDN dialing prefix used to call outside the network.
Dialing Prefix
3. Select and enter the ISDN BRI numbers:
Setting Description
Area Code Specifies the area code for this system's location.
Directory Numbers Specifies the numbers assigned to the B1 and B2 channels for
each BRI line.
The two numbers for a line may be the same or different,
depending on the switch protocol in use.
Enable Specifies whether to enable the associated ISDN line.
If you selected Standard ETSI Euro ISDN protocol, you must
enable all BRI lines that you expect to be active, and you must not
enable lines that will not be connected.
You may want to disable a particular line if there are problems with
the line that generate continuing error messages.
The ISDN BRI Numbers screen also displays information for Country and
Country Code. To specify the system's location, go to System > Admin
Settings > General Settings > Location. The system automatically supplies
the country code when you specify the country.
