NOTE:
On some versions of the switch, the XID setting cannot
be changed. If an error was found, correct it with the
change station command. Otherwise proceed to
step 3.
3. On the switch, busy and release the ASAI station. Use the
status BRI command to check the connection status. It
should become "Layer 3 established" within a minute or so.
4. Restart with the DLG Maintenance option; select "Restart."
5. If the problem persists, reboot the DLG.
NOTE:
All connections will drop when the DLG is rebooted.
Schedule downtime if there are multiple users.
6. If the problem still persists, contact Services.
■ DEFINITY Down — The DEFINITY switch is being rebooted or the
interface between the DEFINITY LAN Gateway and the switch is
down.
The latter may occur if the carrier or cabinet in which the DEFINITY
LAN Gateway is located is not functioning properly.
■ L2 Down — ISDN layer 2 on the DEFINITY switch is not
established. This may occur if the BRI port has been busied out on
the DEFINITY LAN Gateway.
L2 Down can also occur if the DEFINITY LAN Gateway cannot
establish the link with the switch. This may also be a transient
status when the G3PD establishes a connection to the DEFINITY
LAN Gateway or the switch performs a maintenance activity. The
transient cases should not last longer than a few seconds; if they
persist, contact Services.
■ MFB Busy — Services has busied out the BRI port on the
DEFINITY LAN Gateway.
The BRI port may or may not be administered on the switch. If it is
administered on the switch and busied out at the LAN Gateway, this
prevents layer 2 from being established. (In this case, Services is
actively working on a problem; if not, the network manager should
contact Services to release the BRI port on the Gateway.)
■ Invalid Reason — The message received from the DEFINITY LAN
Gateway indicating that the link is down has an unknown reason.
This is an error. If it persists, report to Services.
NOTE:
If one of the following DEFINITY LAN Gateway error conditions is present,
the G3PD automatically tries to establish the link every ten seconds.
