5.1 ASM-MN-214 Card Cage
The ASM-MN-214 card cage contains one or two power supplies and up to 14 plug-in cards. The card types can be ASMi-31/R or other RAD rack version modems/converters - any combination of up to 14 plug-in cards.
For each of the 14 cards, the rear panel (see Figure 5-1) contains a male connector for the terminal block and a DB-25 connector. A protection cover protects the terminal block connectors.
The terminal block (see Figure 5-1) is to be attached to the rear panel terminal block connectors. It contains screws for connecting the transmit and receive pairs and ground, if present.
The 25-pin D-type female interface connector provides all interface signals for the digital interfaces. Modems with X.21 or V.35 interface require an external mechanical adapter.
Two optional interface attachments, CIA/V.35/1 and CIA/X.21, can be ordered separately from RAD. CIA/X.21 converts two adjacent DB-25 connectors to two X.21 15-pin connectors. CIA/V.35/1 converts one DB-25 connector to a V.35 34-pin connector.
V.36 modem cards are supplied with a RAD adapter cable CBL 530/449F, which converts the DB-25 connector to a V.36 37-pin connector. The adapter cable and two interface attachments are also shown in Figure 5-1.
