PERATION
Midian’s TRA is a telephone to radio adapter that can be
used in a wide variety of situations, including: mobile
telephone, rural telephone, in-plant telephone systems,
interfacing office telephones to tone & DC remotes,
interconnect, and mobile to mobile telephone applications.
The TRA has three decode numbers, ANI, 10-number
memory dial and last number redial. The TRA will output
in both two-tone and five-tone formats.
2.1. Controls and Indicators
The TRA is controlled by the Off Hook Condition and the
Keypad of any Touch Tone
®
telephone, including cordless
phones. When the phone is taken off hook, the TRA
checks for an open channel and then sends ANI if that is
programmed. Dial tone is heard in the earpiece unless
the channel is busy, in which case a busy tone will be
heard. Upon receipt of dial tone, the user can begin
dialing.
2.2. Making Calls
In all cases in this section, to make a call, take the phone
off the hook. A dial tone should be heard, unless the
channel is busy, in which case a busy tone will be heard.
Incorrect entries can be cleared at any time by pressing
the # key. When finished, simply hang up the phone.

To make a voice call in any of these systems, follow the
instructions above. If dialing has been disabled, and no
ANI is programmed, when the user picks up the telephone
the TRA will allow the VOX circuit to key up the transmitter
whenever the user talks. At this point, the user can call a
mobile and carry on a conversation.

Using the primary and secondary dialing features, the
TRA can be programmed to dial two types of signaling
formats based upon digit length. For example, the user
could dial a three digit number for two-tone sequential and
a five digit number for five-tone paging. Or, the primary
and secondary dialing locations could be programmed for
Touch Tone.
The user can now dial the desired number. When the
tone sequence is completed a tone prompt will be heard
indicating to the user that he can now give a voice
message. The user can stay on-line at this point and talk
to the unit they called, provided they called a talk-back
paging/portable. If the user called a simple pager, they
should hang up after the message is completed.

LICKS
When the user of a mobile unit wishes to call the base
station, he may rapidly key his microphone button several
times. The TRA will count the number of clicks that are
programmed in
N-Click Decode , and if they arrive within
the time out period programmed in N-Click Timeout , the
TRA will generate a 70V ring to signal the telephone
receptionist, who may in turn page anyone throughout the
building to pick up the line to which the TRA is connected,
and answer the call. If the line rings at each phone, a
receptionist might not be required.
The phone user simply talks into the microphone and the
VOX will then key up the base station or Tone/DC
Remote. When finished, simply hang up the phone. The
user should monitor the channel for any other traffic to
make sure he does not cause interference. The Busy
Lockout feature can also provide this protection when
programmed in
Busy Lockout .
