Exchange Connection:
Connection to the MS series exchanges can be made over the KTS interface and to the
DS series exchanges over either KTS or RS422 interfaces. Signal assignments for the
KTS/RS422 and RS232 connectors have been shown in the figure below. Tips specified
as “NC” indicate that no connection will be made there. The tip RS422_POS and KTS_MS
is common for the KTS and RS422 connection. When a connection is made to a PC over
RS232, 9-pin D-type DCE-DTE serial cable should be used. When the RS422 connection is
made, the cable length should be less than 1 km for copper cable with diameter of 0.5 mm.
