[mgc2200] mtp2 aligment problem

hi,

i have a 5400 working as integrated slt...the c7 link aligns at times but drops after a few seconds. we have looked and avoided every posible hw and sw bug (there were a few, especially one regarding the e1 cards) and keeps happening.

anybody have an idea? here's a few captures:

AS5400#show ss7 mtp2 state

SS7 MTP2 states for channel 0

Protocol version for channel 0 is ITU-T Q.703 (1996) (White Book)

MTP2LSC_OOS MTP2IAC_IDLE

MTP2TXC_INSERVICE MTP2RC_IDLE

MTP2SUERM_IDLE MTP2AERM_IDLE

MTP2CONGESTION_IDLE

Congestion Backhaul = Abate

Remote Processor Outage = FALSE

AS5400#show ss7 mtp2 state

SS7 MTP2 states for channel 0

MTP2LSC_OOS MTP2IAC_IDLE

MTP2SUERM_IDLE MTP2AERM_IDLE

MTP2CONGESTION_IDLE

Congestion Backhaul = Abate

Remote Processor Outage = FALSE

AS5400#

se how it aligns at times? here's a debug:

the connection is to a 5ESS. we've reviewed configurations several times and nothing. maybe we need a fresh mind to look at this...anybody can offer a suggestion?
