8.15 ICP_V24 Connection Data

V.24 interfaces in the SM_V24E are always in DCE mode. One ICP_V24 can serve one SM_V24E module. The
SM_V24E module can work in the following three modes:
Eight channels of transparent without controls mode (Connectors marked SYNC CH1 and SYNC CH2

are not connected.)
Four channels of asynchronous with controls mode (Connectors marked SYNC CH1 and SYNC CH2 and

CH5 to CH8 are not connected.)
Two channels of synchronous with controls mode (Connectors marked CH1 to CH8 are not

connected.)
Two types of connectors for external interfaces are on the front panel of the ICP_V24:
25-pin D-type male connector for synchronous V.24 interfaces

9-pin D-type male connector for transparent or asynchronous V.24 interfaces

The following figure identifies the 25-pin D-type male connector pins as seen when looking into the
connector. The table lists the connector pin assignment for a typical connector and the color of the wire
connected to the corresponding pin in the cables offered by ECI for connecting the tributary connector and
a distribution frame.
