Errors on ATM WAN link

Errors on ATM WAN link

Errors on ATM WAN link

My network is setup to run over a public SDH network in the Middle East.  Currently we have two TNX 210's connected over the SDH backbone serving as the transport nodes. The topology of the network is a hub and spoke. The service nodes at the remote locations are TNX 210's but the hub's service node is a TNX 1100.  Timing for the transport node is provided by the service provider.  Currrently we are experiencing errors (both bit and pattern) during our service-to-service node testing. can this be a timing issue since we have numerous timing sources on the TNX 1100 (a microwave link, the service provider for the fiber link, and the FIREBRED test equipment (interna clock)).  Can someone help us with this problem.  Thanks
