RIC-E1/R Card

This chapter describes the RIC-E1/R card version, designed for installation in the ASM-MN-214 card cage. The chapter contains the following sections:

•The ASM-MN-214 card cage

•The RIC-E1/R card version

•Power supply to RIC-E1/R card

•Installing the RIC-E1/R card.

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 RIC-E1/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.

Line Connector

The line is to be attached to the rear panel terminal block connectors

(see Figure 5-1). It contains screws for connecting the transmit and receive pairs and ground, if present. When operating RIC-E1/R with unbalanced E1 interface, use a CIA/TB-BNC/214 adapter, which converts the terminal block connector into two coaxial BNC connectors (see Figure 5-1).

The ASM-MN-214 card cage is also available with BNC coaxial unbalanced or RJ-45 balanced line connectors.

DTE Connector

The 25-pin D-type female interface connector provides all interface signals for the digital interfaces. Units with X.21 or V.35 interface require an external mechanical adapter. Two optional interface attachments, CIA/X21/1 and CIA/V.35/1, can be ordered separately from RAD. CIA/X.21/1 converts one DB-25 connector to an X.21 15-pin connector. CIA/V.35/1 converts one DB-25 connector to a V.35 34-pin connector.

V.36 converter cards are supplied with a RAD adapter cable CBL-530/449F, which converts between the DB-25 connector and a V.36 37-pin connector.
