number during an outgoing
call
Configured with isdn bch-local-manage command, the router operates in local
B-channel management mode to select available B channels for calls. Despite this,
the connected exchange has higher priority in B channel selection. If the B channel
the router selected for a call is different from the one indicated by the exchange,
the one indicated by the exchange is used for communication.
Configured with the isdn bch-local-manage exclusive command, the router
operates in exclusive local B-channel management mode. In this mode, the B
channel selected by the router must be adopted for communication. In the
Channel ID information element of the call Setup message sent for a call, the
router indicates that the B channel is mandatory and unchangeable. If the
connected exchange indicates a B channel different from the one selected by the
router, call failure occurs.

Local ISDN B channel management is
not configured and the remote end is
responsible for B channel
management by default.
Exclusive local management mode for
ISDN B channels is applied to network
side for the device. If the device
serves as user side connected with
ISDN switch, and the B channel
indicated by the exchange is
inconsistent with the one required by
the local end, call failure occurs.
