For the following output example, the command status signaling-group 1 was
entered.
Port: The physical address of the port transporting either the primary or
secondary D-channel.
Level 3 State: The state of the primary or secondary D-channels. The state can be
"in-service," "standby," "wait," "maintenance busy,"
"manual-out-of-service," "out-of-service," or "no-link."
in-service:A D-channel is "in-service" when it is in the
multiple-frame-established state at layer 2 carrying normal call-control
signaling at layer 3.
standby:A D-channel is "standby" when it is in the
multiple-frame-established state at layer 2, and not carrying any layer 3
call-control messages on logical link 0,0.
wait:A D-channel is in a "wait" state when an attempt has been made by
one side of the interface to establish layer 3 peer communications as
part of the process of going to the "in-service" state. This state is
transitional in nature. As ISDN SERVICE message is sent over the
interface, When the far end of the interface responds with a SERVICE
ACKnowledge message the D-channel is placed in the "in-service"
state.
maintenance-busy:A D-channel is "maintenance-busy" when it is not in
the multiple-frame-established state at layer 2. This state is entered
automatically when an active D-channel is declared failed. A D-channel
which has been placed in the "maintenance-busy" state may be place in
the "out-of-service" state without system technician intervention.
manual-out-of-service:A D-channel is "manual-out-of-service" when
system technician intervention has caused it to be placed in the
TEI-assigned state at layer 2. System Technician intervention is
required to retrieve a D-channel from this state.
out-of-service:A D-channel is "out-of-service" when it is in the
TEI-assigned state at layer 2, but is periodically requested by layer 3 to
attempt to establish the link.
no-link:No link is administered for the D-channel.
