ONFIGURATION OMMANDS
After you specify a BSV interface operating on the network side to be in
■
permanent active state on physical layer using the permanent-active
command, no deactivating request is sent to physical layer. In this case, the
interface remains in the active state if it is up and the physical link operates
smoothly.
The permanent-active command functions differently comparing with the
■
isdn q921-permanent command. The former maintains the active state of BRI
interfaces on physical layer and is only applicable to BRI interfaces operating on
the network side. It cannot activate the BRI interfaces that are in inactive state
on physical layer. The latter, however, enables ISDN BRI interfaces operating on
user side to set up and maintain Q.921 links automatically. If no Q.921 link is
established, the isdn q921-permanent command triggers the ISDN BRI
interface to establish Q.921 links.

The support for these two commands varies with device models.

boards and operating on network side.
