Before setting up the ViewStation to an ISDN network, ensure all
network connectivity issues are tested and resolved.
ViewStation H.323 with Quad BRI
The ViewStation H.323 with Quad BRI uses up to four ISDN lines for
network connectivity and requires a Polycom Quad BRI inverse
multiplexer. The Quad BRI provides connectivity at a maximum
H.320 data rate of 512 Kbps. Complete the following steps to
connect the ViewStation H.323 with Quad BRI to the network:
1. Connect four ISDN lines from RJ-45 wall jacks on the ISDN
network to the connectors labeled ISDN S/T on the Quad BRI
network interface module.
2. Connect the green-tipped RJ-45 cable to the green RJ-45 port
on the back of the ViewStation as shown on the QuickStart card.
3. Connect the opposite end of the green-tipped RJ-45 cable into
the green RJ-45 port labeled
x on the Quad BRI
network interface module.
NT-1. If you are connected to an internal phone system, commonly
called a PBX, you need to connect the ISDN cables from the Quad
BRI network interface module to an ISDN network termination
(NT-1) device, which is connected to the ISDN wall jack.
For more ISDN information, refer to the Appendix D, ISDN
Information," on page 203.
Once the interface is properly connected, the ViewStation H.323
with Quad BRI is ready to be configured for Ethernet LAN
connectivity.
ViewStation H.323 with Avaya DCP
The ViewStation H.323 with Avaya DCP uses up to four DCP lines
for network connectivity and requires an Avaya DCP inverse
multiplexer. The Avaya DCP inverse multiplexer provides
connectivity to conduct videoconferences at a maximum H.320 data
