Description: The signalling state that represents the active state. For E1 ports and T1 ESF ports, these bits represent the ABCD signalling bits on the interface. For T1 SF ports these bits represent ABAB signalling bits. ` x' means don't care. The range is from 0000 to 1111.

What is cdx6500VoiceCfgT1E1RxActiveOffhookState?

The 4-bit ABCD signaling pattern this port recognizes on receive as the active/offhook state, with 'x' don't-care bits, range 0000-1111. It's configured to match the CAS bit convention used by the connected T1/E1 equipment for signaling a call in progress.
