The DM-24 adapter consists of a mother board/daughter board combination. The user-
configurable switches on the adapter are located on the back side of the mother board.
Note:
“ON” and dip switch numbering (“1”,”2”, etc.) may be labeled on opposite sides of the
switch, but the “ON” switch position is always to the right as illustrated in the appendix.

DM-24+
AND
DM-30+
The DM-24+ and the DM-30+ adapters consist of a mother board/daughter board combination.
The two adapters closely resemble each other; they are distinguishable by the number of modem
chips on each of the boards. The DM-30+ with its 30 modems is suitable for E1 (European) trunk
lines. The DM-24+ (24 modems) accommodates T1 trunk lines in the US and Japan.
To support the ITU V.90 standard, the DM-24+ and DM-30+ must be of a certain hardware revision
level. The adapter’s mother board must be REV K or higher; the daughter board must be REV G or
higher.
Revision label and pertinent switches are located on the back side of the mother board.
