CAB-MTCE (Media Gateway Maintenance)
G650
Avaya Communication Manager 2.0 introduces the G650 media gateway. The G650 media
gateway does not support the traditional maintenance board (TN775D), therefore
environmental maintenance is performed by the TN2312BP IPSI circuit pack. The CAB-MTCE
MO is used to allow the alarming and logging of environmental maintenance errors for the
TN2312BP IPSI in a G650 media gateway. Since the TN2312BP IPSI supports environmental
maintenance in the G650 media gateway, trouble with the TN2312BP IPSI may cause
environmental maintenance to falsely detect problems. The following environmental MOs may
be affected:
● CAB-EXFR (emergency transfer) on page 739
● CAB-CALM (Customer alarm) on page 737
● CAB-PFL (Power Fan Lead) on page 749
● SER-BUS (Serial communication bus) on page 1957
● EXT-DEV (External device alarm) on page 1240
When the TN2312BP is used in the SCC1 and MCC1 media gateways the collocated TN775D
Maintenance circuit pack performs environmental maintenance.
When the TN2312BP IPSI is used in a G600 or CMC1 media gateway it monitors environment
maintenance (power supply and fans) using the AuxSig lead.
Initialization
Initialization Test (#1548) is executed when an IPSI is inserted and the board and media
gateway type is determined. When a TN2312AP is inserted in a CMC1, G600, or G650 the
Power Fan Lead (AuxSig) environmental maintenance is enabled.
When a TN2312BP IPSI is inserted in either a CMC1 or G600, Communication Manager sends
the following messages to the embedded software (firmware) on the board:
● Enable environmental maintenance (Power Fan lead)
● A query to verify that environmental maintenance is enabled
