About Cisco IPVC 3500 Series Gateway ISDN Network Connections

The Cisco IPVC 3521 BRI Gateway features four BRI ISDN connections. Each BRI line provides two
B channels and one D signalling channel.
The Cisco IPVC 3526 PRI Gateway and Cisco IPVC 3540 PRI Gateway feature 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.
You can connect the gateway directly to a PRI or BRI line provided by your local ISDN provider, or to
