Adding a Voice Processing Card

1.Set the bank of eight DIP switches (switch S1) and the bank of four DIP switches (switch S2) on the card being installed as shown in Figure 7-5.

Outside of the United States, some telephone networks provide a tone similar to the U.S. busy tone to signal that the far-end caller has hung up. In these situations, the third DIP switch on switch S2 on each PARTNER MAIL card must be set to the "On" position to enable the mail system to detect and react properly to this signal. This switch should never be set to "On" for systems installed in the U.S.
