View

Parameter
None
Description
Using the isdn bch-local-manage command, you can enable local ISDN B channel
management. Using the undo isdn bch-local-manage command, you can disable
the setting.
It is very important to put appropriate control on the B channels used for calls in
process, especially in the PRI mode. Proper channel management can improve call
efficiency and reduce call loss. Normally, the centralized B channel management
provided by exchanges can work well. For this reason, you are recommended to
adopt the management function provided by exchanges in most cases, despite the
ISDN module can provide the channel management function as well.
Example
Enable local ISDN B channel management.
