1 byte,
value of 0 thru 8
Command or Query.
Sets or returns Terrestrial interface type in the form x, where:
0=EIA-422/EIA530 DCE
1=V.35 DCE
2=EIA-232 (sync).
3= G.703 T1 AMI (forces Rx and Tx data rates to 1544 kbps)
4= G.703 T1 B8ZS (forces Rx and Tx data rates to 1544 kbps)
5= G.703 E1 Unbal AMI (forces Rx and Tx rates to 2048 kbps)
6= G.703 E1 Unbal HDB3 (forces Rx and Tx rates to 2048 kbps)
7= G.703 E1 Bal AMI (forces Rx and Tx rates to 2048 kbps)
8= G.703 E1 Bal HDB3 (forces Rx and Tx rates to 2048 kbps)
9 = IP Interface
A = IP-ACM (valid only in CDM-570A Compatibility Mode (CMO=1))
B = VersaFEC-2 ACM (requires VFEC-2 option card)
Example: <0/ITF=2 (V.35)
Note: When ITF is set as G.703, Clock Extension Mode is automatically set as
