McTi Digital Telephony Connections (McIAS 1607, 1610 and 1623/IP only)

The following sub-sections describe the process of connecting McTi-24 and McTi-30
boards from the McIAS unit to telephone company equipment. (If applicable, see
Section 2.9 for information about connecting the optional McTi-MR boards or Section
2.8 for information about optional V/S24T1 and V/S30E1 connections.)

McTi-24 Digital Connections

DB15F (female) connectors, located on the back of the McIAS, are used to connect
each McTi-24 board to the telco trunks. The channels associated with each digital
connector are discussed in Section 2.3.
The table below lists the DB15F pin connections.
Note: It is a good practice to test internal McTi-24 connections using a loopback
connector (DB15M male) attached directly to the digital backplane connector with
pins 1 & 3 and 9 & 11 jumpered together. A successful test will result in the
illumination of the green NORMAL LED on the front panel of the McTi-24 board
installed in the slot associated with the connector being tested.
