Note:
On the 7210 SAS-T and 7210 SAS-Mxp, BITS2 inherits the values configured for BITS1.
The no form of this command reverts to the default configuration.
Default
ds1 esf
Parameters
ds1 esf
Specifies Extended Super Frame (ESF). This is a framing type used on DS1 circuits that
consists of 24 192-bit frames, The 193rd bit provides timing and other functions.
ds1 sf
Specifies Super Frame (SF), also called D4 framing. This is a common framing type used
on DS1 circuits. SF consists of 12 192-bit frames. The 193rd bit provides error checking
and other functions. ESF supersedes SF.
e1 pcm30crc
Specifies the pulse code modulation (PCM) type. PCM30CRC uses PCM to separate the
signal into 30 user channels with CRC protection.
e1 pcm31crc
Specifies the pulse code modulation (PCM) type. PCM31CRC uses PCM to separate the
