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, ignore.
0 = Closed Net Mode
1 = IDR Mode
2 = IBS Mode
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, ignore
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, ignore
0 = Voice, 1 = 64 K Data
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, ignore
Bit 0 = IDR Backward Alarm 1
Bit 1 = IDR Backward Alarm 2
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, ignore
0 = G.703 Unbalanced E1
1 = G.703 Balanced E1
2 = G.703 T1, B8ZS
If synchronous multiprotocol daughter card is installed:
0 = V.35, 1 = RS-422, 2 = RS-232
Note: The following two bytes apply only if an IDR OR IBS
interface card is installed and the Receive Mode is set to
