Receiving Phone Calls at the Two-Way Radio

The OSMAC Base Station can also be used to route telephone calls from the telephone line to a two-way radio.

To initiate a phone call from the telephone interface:

1. Dial the phone number of the telephone line connected to the OSMAC Base Station.

2. The telephone user must press the

 5 keys to request a phone call if REMOTE PAGING is enabled.

3. If Call Forwarding is enabled and the telephone line rings, the base station will transmit a simulated ring signal over

the air. To answer the call, a mobile user must press the

 key to take the telephone line off-hook.

4. Once the called party answers, the phone VOX circuit takes over. When the phone user speaks, the Base Station

transmits his or her voice.

5. A periodic ticking sound will be heard by the mobile user as the base station briefly switches from transmit mode to

receive mode to determine whether the mobile user wishes to interrupt the conversation and has begun transmitting.

6. If neither party is talking, a single beep will be heard periodically to remind the mobile user that the phone patch is still

in operation.

7. A time-out timer exists in order to shut down the phone patch automatically in the event that the mobile user goes out

of range or has a battery outage. The length of the timer is set in the Configuration Menu. Warning beeps or a voice

message will be sent a few seconds before the time-out timer expires and the phone call is terminated. The mobile

user must press the

 key to reset the time-out timer and continue the phone call.

8. End the conversation from the two-way radio by pressing the # key. A high, then low beep sequence or a voice mes-

sage should be heard to confirm the disconnect.

Note: If uncertain about the settings of Remote Paging and Call Forwarding modes, contact your local Toro distributor or

field service representative.
