OOS (Busy Out) Toggle Switch

The front panel has a two-position out of service (OOS) switch. Use this switch to take the modem off-hook,

which creates a busy condition for the modem.

● Move the OOS toggle switch to BUSY to take the modem out of service. The OOS and OH LEDs light and

incoming calls get a busy signal.

If you suspect a modem is not working, use BUSY to have an optional device, such as a hunt group, roll the call to

the next available modem while you check the busy modem.

Out of Service Test Jumper

When the MT5600BR-V92 is out of service, it is busy to incoming calls. In the Test (default) setting, the modem

drives pin 25 high when the modem is in Test mode. The OOS (optional) setting forces pin 25 high and puts the

modem in a busy condition.

Note: Jumper (shorting) plugs do not shipped with the MT5600BR-V92, but Multi-Tech Technical Support

will provide jumper plugs on request.
