Analog Telephony Connections (McIAS 1685, 1607 and 1610 only)

3.1 McTi-8E (4-wire E&M) Connection
An analog connection from the McTi-8E board(s) to the telco is made via the female
50-pin connectors on the exterior backplane. The McIAS 1607 and 1685 analog
interface connectors are identified as J3 and J4 which together handle a maximum
of 8 channels. The McIAS 1610 connectors are J3, J4, J6 and J7 which together
handle up to 24 channels. (An optional analog connector block can be used to make
a connection from the McIAS backplane connectors to the telco end.)
McTi-8E pin connections are shown below.
