Chapter 5
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.
