OTE: The number of wires used depends on the mode of each channel. All 18 pairs of wires
are used for the SM_EM_24W6E module if all channels are in four-wire E&M mode.

8.13.3 Connection Data for SM_V24E Interfaces

The SM_V24E module supports the following three modes:
8 x V.24 transparent without control signals

4 x V.24 asynchronous mode with control signals

2 x V.24 synchronous mode with control signals

In 8 x V.24 transparent mode, the SM_V24E supports eight channels, each with three wires. The following
table lists the pin assignment for a typical connector when the SM_V24E is in 8 x V.24 transparent mode.
This table also lists 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.
