Controller T3 Line Code Issue

Controller T3 is set to M23 B8ZS, but port xmt'g D4? DACS is ESF THRU...

Is there another setting I am missing? We have other interfaces on the router working fine, I have verified and matched the configs between the two.

Sorry, I'm not sure what do you mean, what the question is.

Re: Controller T3 Line Code Issue

The ckt is ESF B8ZS all the way from the fare end to the interface in the router. The facility/DACS and router is configured for ESF B8ZS, but when I look at it with a T-BIRD (because interface won't come up) The router interface in transmitting D4, not B8ZS?

Hi,

not sure why the t-bird sees D4. Cisco T1 interfaces never supported that.
