ONNECTIONS
The RADVISION PRI Gateway features configurable E1/T1 PRI ISDN
connections. When configured as an E1 connection, each port provides 30 B
channels and one D signaling channel. When configured as a T1 connection,
each port provides 23 B channels and one D signaling channel. The type of line
available depends on your local ISDN provider. You configure the Gateway PRI
port to an E1 or T1 interface accordingly. In addition, you can choose to activate
only specific channels by using fractional channel selection.
