2.4OOS (Busy Out) Toggle Switch

The MT2834 contains a two-position OOS switch on the front panel. This switch can be used to create a “busy out” (OOS) condition for the modem (i.e., take the modem off-hook). To place a modem in the Busy condition, move the OOS toggle switch to the (BUSY) position. The modem then goes off-hook, its OOS and OH LEDs light, and incoming calls to this modem get a busy signal. If you suspect a problem with a particular modem, you can use the BUSY switch to have an optional device (such as a “hunt group”) that looks for a non-busy line to perform a “roll over” to the next available modem while you check the status of the Busy modem.
