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.
