ISDN BRI WAN Interface Card Independent of Host
ISDN BRI WAN Interface Card Independent of Host
The one-port ISDN Basic Rate Interface (BRI) Wide Area Network (WAN) Interface Card is an interface
card assembly for use within a range of data communication (gateway and router) chassis supplied by
Cisco Systems. Two versions of the card are available, one with a built-in Network Termination 1 (NT1)
device and one without.

The BRI WAN interface card mounts in a slot, labeled W0 or W1, which is one of the two slots available
in a Cisco 1700 Series router. The BRI WAN interface card provides all of the hardware necessary to
allow connection of the Cisco 1700 series chassis to one Basic Access Integrated Services Digital
Network (ISDN) at the S-reference point. The ISDN usage is restricted to point-to-point mode only.

connection for each ISDN port.
connection for each ISDN port.
The ISDN connection must be made to a network connection point that is provided by one network
vendor or public telecom operator (PTO) to ensure that common network timing exists between the
ISDN ports used. Failure to observe this point may result in lost (nonrecoverable) data packets because
of timing slips.
