Section 3. Operation
3-5
Direct to Air
The user may program the unit to place the received call Direct to Air. If this
function is enabled, it places the caller on the air without waiting to get a
response from the mobile user to complete the call. This type of operation is
particularly useful for in-house systems where the Model 30 is on an extension of
a PBX.
Autodial
The Model 30 allows up to 50 autodials to be stored for speed dialing. To access
the autodials, the user enters his/her connect code and, within 1 second, the
autodial number. For example, if the connect code is “*” and the mobile wishes
to autodial the phone number stored at location 5, the user enters “*5”, and the
number is dialed. Up to 16 digits may be programmed into each autodial slot.
Mobile users can be restricted to only accessing the phone by using the Autodial
numbers. If a mobile user initiates a call while this feature is enabled, that user
can only request a valid Autodial number. If the user tries to dial a regular phone
number or to access an Autodial slot that is empty (not programmed), the call is
be terminated and the Model 30 issues an error tone (warble) on the channel
before unkeying the transmitter.
Hook-Flash
The hook flash, when enabled, allows the mobile to flash the telephone line. For
example, if you are on a PBX system, the PBX may require a hook flash to
perform certain functions. To flash the line, the user sends a “*0” during a call.
Non-DTMF Access to Phone Line
When enabled, non-DTMF equipped mobiles can gain access to the phone line
by simply keying up four times in rapid succession. If four carrier signals are
received less than 1 second apart, the phone line will be taken off hook and
autodial #1 will be dialed. The phone side can disconnect the call by sending
“#0”.
Auxiliary Output Control
The Auxiliary Output allows an external device at the radio site to be controlled
with DTMF over the radio channel or from the phone. This is useful, for
example, to control an antenna switch for coverage of multiple areas. The
Auxiliary Output is controlled by entering different codes to turn on or off the
output. This can be accessed from either the radio or the phone. The factory
defaults for these codes are 567 to turn “on” the output and 890 to turn “off” the
output. These may be programmed by the user to be any code of up to nine digits
each. When the On code is decoded by the Model 30, the FET on the Auxiliary
Output will be switched on which pulls the open drain line to ground. The FET is
capable of sinking a maximum of 200 mA DC. The output stays in the assigned
