A.1.4.2 Circuit Connectors
The MA-308C module adapter provides four RJ-45 circuit jacks on the right. With eight leads available,
Types I, II, III, and V E&M signaling is supported. The MA-308C also provides per-channel attenuation
for compatibility with tandem connections. MA-308C has the capability to connect/disconnect a single
channel connector without disturbing traffic on the other three.
A.1.4.3 Monitor Connectors
The MA-308C module adapter provides four RJ-45 monitor jacks on the left for monitoring the input
and output VF and signaling levels for each of the four channels. Cables terminated with modular
plugs can be inserted into and removed from the modular jacks at any time. The MA-308C module
adapter enables interface signal monitoring of the input and output VF signal levels, the E and M
leads, and SB and SG. Each RJ-45 monitor is wired to bridge its associated RJ-45 VF leads as well as
SB and SG and E and M leads.
A.1.4.4 Modular Connector Wiring
Figure A-6 shows how to wire the modular connectors, conforming to cabling standard T568A and to
USOC RJ1CX. The MA-308C accepts a RJ-45 connector. Table A-11 shows the pin assignments on this
connector.
