Table 3-10. E1/T1 Parameters (Cont.)
Parameter Possible Values / Remarks
Line Type Line type affects the number of bits per second that the link can reasonably
carry. It also affects the interpretation of the port performance statistics.
For E1 ports:
Framed (G.704), Framed-CRC, Framed-MF, Framed-CRC-MF
Unframed (G.703): Use when the data being transmitted is unframed
For T1 ports:
ESF: Extended SuperFrame
D4: AT&T D4 format
Unframed: Use when the data being transmitted is unframed

(only applicable for T1
ports)
Type of Zero Code Suppression used on the link

Idle Code
(not applicable when the
Line Type is unframed)
Byte pattern of the data transmitted in the E1/T1 Framer idle timeslots
0 to FF

(only applicable for T1 ports with the Line Mode DSU)
Tx Gain (dB)
(only applicable for T1

Restore Time (sec)
(only applicable to T1
ports. Not applicable
when the Line Type is
unframed)

Used to change the sync. Algorithms to reduce the time required for the port to
return to normal operation after a RED (LOF – loss of frame synchronization)
alarm.
