Command Reference Guide
Description
Using the e1 set frame-format command, you can configure the frame format
for an E1 line. Using the undo e1 set frame-format command, you can restore
the default setting.
By default, the frame format no-crc4 is used for E1 line.
Only if an E1 line is working in framed format (which can be set by using the
undo e1 unframed command) can this command be configured.
For related command, see e1 unframed.
