Calls getting disconnected on Meridian option 11C

[havock10]

Hello, I was wondering if anybody had any idea on how to solve this problem... We have a Meridian Option 11C here in Mexico with about 20 Did's and 10 Tie Lines to a city in the U.S. about 500 miles away... We have an E1 line to San Diego and then there's an T1 line to our mother company in that city (which has the same system)....

We have about 40 Analog phones and 50 Digital ones.

A lot of our users have gotten they're phone calls disconnected to the U.S. and Canada .... some of them 70% of the time... National calls to Mexico don't have that problem... anybody have any ideas of what the cause could be? I'm sort of new at this, any help would be appreciated.

Thanks.

your ixc carriers most likely are having the problem thru their trunking eq. ask your cust to contact these carriers that are transporting paticular routes out of country
may be a place to start since it is intermittent prbl. very seldom is a problem of this nature in cust equip.

Thanks for the help... The Nortel people checked our passport remotely and traced the problem to a software/hardware glitch ... They're sending a replacement card now... THey told us it was an ASBIC Aspect parity problem, whatever that is...
