(ASCEND) Odd Framing on a Pipeline 130
Hi. We have two Pipeline 130s connected across a 128K fractional T1. The
problem is we are getting mysterious packet loss on the connection. We
have replaced both units thereby eliminating the possibility of a bad CSU.
The Telco has done extensive testing on the line and still swears that all
test run clean.
They suggested that the trouble could be something that the Pipeline is
doing under normal operation. The tech said that it may be
trying to steal extra bandwidth by shoving additional data into the
reserved upper frame segment. Since the T1 is deframed and stripped to 2
channels at the switch this extra data would be lost. His theory is
supported by the fact that the problem get much worse under load. The
Pipeline could be trying to stuff even more extra stuff in. Does any one
know of a similar case? Is this really something the Pipeline 130 does
normally?
I should also mention that we are in Canada and I'm not sure if there's
some difference between the Canadian standard and the standard the Pipe
was built for. We are using ESF B8ZS.
Thanks for any help you can give me.
