1351 - Discrd Trans Lrg MSU Unsupported SLK

An MSU less than 5 bytes or greater than 279 bytes was detected by the MTP layer 3 software in an ATM card. A four-byte MSU may cause the ATM connection to bounce (four byte PDUs are used for SSCF control). The MSU length limit is 279 bytes. IN this case, an SSEDCM-IPLIM SAAL/TALI signaling link receives from IMT a large MSU greater than 272 bytes. The discard occurs on the outbound card.

Example

RLGHNCXA21W 00-02-07 12:01:43 EST  EAGLE 37.0.0
0003.1351    CARD 1105,B   INFO     Discrd Trans Lrg MSU Unsupported SLK
             LEN=475
             SIO=0D   OPC=001-001-001    DPC=002-002-002
             LSN=ABCD123
             Report Date:yy-mm-dd  Time:hh:mm:ss

Note:

The length of the MSU (for example, LEN=50) includes the length of the SIF plus some other parameters. The length of these other parameters varies depending on the protocol managed by the LIM card issuing the UIM.

Alarm Level: No alarm condition. The message is informational only.
