T1/E1 & T3/E3 Commands
XSR CLI Reference Guide 2-67
Syntax
framing {sf | esf} (T1)
framing {crc4 | no-crc4} (E1)
framing {c-bit | m13} (T3)
framing {g751 | bypass} (E3)
Syntax of the “no” Form
Return to the default framing setting by using the no form:
no framing
Defaults
• T1: ESF
• E1: CRC4
• T3: c‐bit
• E3: g751
Mode
Controller configuration: XSR(config-controller<xx>)#
Example
The following example configures the T1 controller on NIM card 0, port 0, with ESF framing:
XSR(config)#controller t1 1/0
XSR(config-controller)#framing esf
This example sets the T3 controller with line source clocking, M23 framing, and channelized mode:
XSR(config-controller)#channelized
XSR(config-controller)#clock source line
XSR(config-controller>T3-1/2/0>)#framing m13
Note: The C-bit T3 parity framing format is an enhancement of the original M13 format. The main
difference is the C-bit framing format always stuffs the first bit of the 8th block in each sub-frame. So,
in C-bit format, C-bits permit greater management and performance functions on the M frame.
sf T1 frame type set to Super Frame (D4, F12).
esf T1 frame type set to Extended Super Frame.
c-bit T3 frame type set to C‐ bit.
m13 T3 unchannelized frame type set to M13.
crc4 E1 frame type set to CRC4 frame.
no-crc4 E1 frame type set to no CRC4 frame.
g751 E3 frame type set to G.751.
bypass E3 frame type set to be bypassed. Unchannelized implied.
