*Run the Short Test Sequence first. If all tests pass, run the Long Test Sequence. Refer to the appropriate test description and follow the recommended procedures.
**pp is 24 for 24-channel interfaces and 16 for 32-channel interfaces.

Notes:

• (a) The D-channel is demand busied out. No calls can be made over this D-channel.
• (b) This Error Type indicates that the Media Module has been removed or has been insane for more than 11 minutes. To clear the error, reinsert or replace the Media Module.
• (c) Link error. This error occurs when the port receives an invalid frame over the D-channel. This error normally indicates an off-board problem usually related to transmission errors on the DS1 facility. Execute list measurements ds1-log for the MM710 Media Module on which the D-channel resides. If the DS1-MM is reporting some errors, then the DS1 facility has experienced transmission problems which could have caused the ISDN-LNK to report a Link Error.

If the DS1-MM is not reporting errors, execute the long test sequence for the D-channel. Investigate any errors. If there are none, execute a long test sequence for the MM-DS1 Media Module. Investigate any errors.

If no errors could be found by testing, the Link Error is probably not affecting service. However, if this Link Error continues to be logged, follow normal escalation procedures.

• (d) DS1-MM Interface Media Module is out-of-service. Look for and resolve DS1-BD errors in the Hardware Error Log.
• (f) Bad DLCI error. This error occurs when a LAPD frame is received across the DS1 facility which contains a DLCI which does not have a valid entry in the on-board translation memory. This error normally indicates an off-board problem usually related to a broken endpoint or a state mismatch between a remote endpoint and the local call processing software. Maintenance will not start any testing or generate any alarms in response to this error.
• (g) Receive FIFO Overflow error. This error occurs when the Media Module detects an overflow of its receive buffers. If it occurs frequently, it may indicate a LAPD parameter mismatch between the two end-points of a packet switched connection. LAPD should be able to recover from this problem, but it may degrade the performance of the LAN Bus. Maintenance will not start any testing or generate any alarms in response to this error.
