Description
Bri2/4/0(User-side): ACTIVE
Physical layer activation state of the interface:
• ACTIVE—The physical layer is active.
• DEACTIVE—The physical layer is inactive.
The command displays the physical layer activation state only for BRI
interfaces. The physical layer of a BRI interface is activated only when it
receives an activation request from Q.931. However, the physical layer
of a PRI interface does not require an activation request. It becomes
active when the physical link comes up.
The ISDN role of the interface is bracketed.
Link Layer
Data link connections on the ISDN interface. ISDN establishes a
connection for each terminal and uses a TEI to identify each connection.
A BRI interface can have eight connections, but a PRI interface can have
only one connection.
TEI
Terminal endpoint identifier that identifies an end-user terminal such as
an ISDN phone. TEIs are assigned by the network side.
