framing [d4 | esf]
Use the framing command to configure the framing format for the DSX-1 interface. This parameter
should match the framing format set on the external device. Use the no form of this command to return to
the default value.
Syntax Description
d4 D4 superframe format (SF)
esf Extended superframe format
Default Values
<format> esf
Command Modes
(config-t1 1/1)# T1 or DSX-1 Interface Configuration Mode required.
(config-t1 1/2)#
Functional Notes
A frame is comprised of a single byte from each of the T1’s timeslots; there are 24 timeslots on a single T1
circuit. Framing bits are used to separate the frames and indicate the order of information arriving at the
receiving equipment. D4 and ESF are two methods of collecting and organizing frames over the circuit.
Usage Examples
The following example configures the DSX-1 interface for D4 framing:
(config)#interface t1 1/2
(config-t1 1/2)#framing d4
