bitsPortFrameFormat
Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::bitsPortFrameFormat
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.16.1.11
Node type: OBJECT-TYPE
Type: BitsFrameFormat
Access: read-write
Description: This object represents the BITS Port Frame Format. When the port is configured for a Line Type of T1, the valid values are t1-sf and t1-esf and the default value is t1-esf. When the port is configured for a Line Type of E1, the valid values are e1-unframed, e1-crc4, and e1-dualFrame and the default value is e1-crc4. When the port is configured for a Line Type of 2048kHz, the value is none.
R4.1CC and R4.3CC do not support e1-unframed.
What is bitsPortFrameFormat?
This object configures how timing signals are framed on a BITS (Building Integrated Timing Supply) port, which is used to synchronize equipment to a precise time reference. The valid frame format depends on the port's line type: for T1 lines you can choose between SF (Super Frame) and ESF (Extended Super Frame), while E1 lines support unframed, CRC4, or dual-frame formats. Network operators set this to match the timing standard being supplied by an external clock source.
