0 = V.35, 1 = RS-422, 2 = RS-232
Note: The following byte applies only if a synchronous
Multiprotocol interface card is installed. If not, set to zero.
0 = V.35, 1 = RS-422, 2 = RS-232
Note: The following byte applies only if a symmetric G.703
interface card is installed. If not, set to zero.
0 = G703T1AMI, 1 = G703T1B8ZS, 2 = G703BE1, 3 = G703UE1
Note: The following byte applies to all DMD2401 modems,
regardless of interface type
0 = Normal, 1 = Swapped
Note: The following byte applies only if an IDR OR IBS interface
card is installed. If not, set to zero.
0 = Closed Net Mode, 1 = IDR Mode, 2 = IBS Mode, 3 = Drop & Insert

Note: The following byte applies only if an IDR OR IBS interface
card is installed and the Receive Mode is set to IDR Mode. If not,
set to zero.
0 = Internal, 1 = External
Note: The following byte applies only if an IDR OR IBS
interface card is installed and the Receive Mode is set to
IDR Mode. If not, set to zero.
0 = Voice, 1 = 64 K data
Bit 0 = IDR Backward Alarm 1 / IBS Backward Alarm

Bit 2 = IDR Backward Alarm 3
Bit 3 = IDR Backward Alarm 4
Bits 4 - 7 = Spares
(0 = Mask, 1 = Allow)
Note: The following byte applies only if an IDR OR IBS interface
card is installed and the Receive Mode is set to IDR Mode. If not,
set to zero.
