Module: VOICE-OPT-MIB

OID (symbolic): VOICE-OPT-MIB::cdx6500VoiceCfgT1E1NoRingingState

OID (numeric): 1.3.6.1.4.1.449.2.1.2.1.1.25.1.1.35

Node type: OBJECT-TYPE

Type: DisplayString

Access: read-only

Description: The signalling state that represents the no ringing 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 cdx6500VoiceCfgT1E1NoRingingState?

The 4-bit ABCD (or ABAB) signaling pattern recognized on receive as the 'not ringing' state, with 'x' don't-care bits, range 0000-1111. It complements the RingingState object so the port can distinguish a true ring pattern from steady-state non-ringing signaling.
