Configuring E1 Physical Interface Properties
To configure E1-specific physical interface properties, include the e1-options statement
at the [edit interfaces interface-name] hierarchy level:
[edit interfaces interface-name]
e1-options {
bert-error-rate rate;
bert-period seconds;
fcs (16 | 32);
framing (g704 | g704-no-crc4 | unframed);
idle-cycle-flag (flags | ones);
invert-data;
loopback (local | remote);
start-end-flag (filler | shared);
timeslots time-slot-range;
}
