Power-Source - HP MSR series Command Reference Manual

Usage guidelines
This command is only applicable to ISDN BRI interfaces on BSV boards and operating on network side.
After you specify a BSV interface operating on the network side to be in the permanent active state at the
physical layer using the permanent-active command, no deactivating request is sent to the physical layer.
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 at the physical layer and is only
applicable to BRI interfaces operating on the network side. It cannot activate the BRI interfaces that are
in the inactive state at the 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 following matrix shows the command and router compatibility:
