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
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,
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 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,
set to zero.
If G.703 daughter card installed:
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 IDR
Mode. If not, set to zero.
