To connect to other 4-wire communication systems, do the following:

1. Construct 9-pin or RJ-11 cables to connect from the 4-wire system to the DSI 2008.

To connect to the System A hybrid, use either J2A or J3A; for the System B hybrid, use either J2B or J3B. Pin

connections are as follows:

2. On the DSI 2008 front panel, set the 4W LEVEL REF SEL switches to the position which most closely matches the

audio input and output levels of your 4-wire system.

NOTE: If you don’t know the levels, select the +8dB position for now.
