Controller T3 Line Code Issue

[regasfrvzw]

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.

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.
