frame-format (CT1/PRI interface view)
Syntax frame-format { esf | sf }
undo frame-format
View CT1/PRI interface view
Parameter sf: Sets the framing format to super frame (SF).
esf: Sets the framing format to extended super frame (ESF).
Description Use the
frame-format command to set the framing format on the CT1/PRI
interface.
Use the
undo frame-format command to restore the default, that is, esf.
CT1/PRI interfaces support two framing formats, that is, SF and ESF. In SF format,
multiple frames can share the same FSC and signaling information, so that more
significant bits are available for transmitting user data. The use of ESF allows you
to test the system without affecting the ongoing service.
Example # Set the framing format of interface T1 2/0 to SF.

Parameter 7e: Sets the line idle code to 0x7E.
ff: Sets the line idle code to 0xFF.
Description Use the
