Powerdial - Radio Comms

Powerdial

"POWERDIAL" is a versatile system for remote control of a radio base station (or similar equipment) from an ordinary telephone. Simply take the base station with Powerdial fitted, to site, plug into an ordinary phone socket and attach to an antenna. The base station can now be controlled from any telephone, even a mobile phone, provided the operator has the correct security access code. Functions include: Speech to and from the mobiles, Switchable talkthrough for Mobile to Mobile calls, Channel change (up to 128 channels), Priority transmit, and a transmitter or site alarm.

Functions are confirmed by user friendly voice prompts which the operator hears down the phone line. A system normally comprises a Transceiver, Power supply, Powerdial controller and a Phone Patch.

When not in use as a dial up base station, the system can be used as a stand alone phone patch for mobile to telephone calls and vice versa.

Powerdial is uniquely versatile in that it does not require any specialist equipment at the operator end, and the base station can be left for long periods, without the phone connection, for use as a talkthrough repeater. The cost of the system can often be saved by removing the need for a fixed leased line at a particular event.

Key Benefits

  • Can be controlled from any telephone.
  • Switchable talkthrough for Mobile to Mobile calls.
  • Can be used as a stand alone phone patch for mobile to telephone calls and vice versa.
  • Does not require any specialist equipment at the operator end.

Flexibility

Your Radio System can be set up anywhere with a phone line (or cellular phone with a "BT" style socket) and accessed from anywhere with a telephone or mobile phone. There are virtually limitless possibilities!

There is no need to previously arrange a land line connection, simply turn up and dial up. . A leased line normally has to be rented over a fixed minimum time period, often outweighing the cost of a dial up call by a substantial amount.

Major Cost Savings

A leased line normally has to be rented over a fixed minimum time period, often outweighing the cost of dial up calls by a substantial amount.

High Degree of User Confidence

Operators hear clear voice prompts when keying in commands to confirm the functions requested. All but the most extremely noisy phone lines will allow reliable control using an advanced DTMF decoder in the PowerDial.

Can Be Used as a Phone Patch

Once the Base Station is on site, it can be used as a telephone patch to allow mobiles to make phone calls, or telephones to call individual or groups of mobiles.

Dial Up Control

Dial up control is achieved by dialling the number of the phone socket into which the base station is plugged from any DTMF telephone. Two ringing tones are heard then a short burst of second dial tone. After this, dial in the security access code and the connection is made to the mobiles. The operator does not have to press a PTT button during conversation as the system is automatic. Mobiles simply key up when they need to talk to the operator.

The operator controls the functions of the base station by keying in the required code on the DTMF telephone. A phone with memories is useful as this speeds up the process and functions can be changed with single key strokes. A keypad and headset arrangement gives the operator a "control room" environment to work with, indeed any control room equipment with access to the telephone network can call the base station and where capable, patch calls to other fixed or dial up sites. e.g.

  • Talkthrough On 9011
  • Talkthrough Off 9010
  • Priority Tx On 9021
  • Priority Tx Off 9020
  • Channel Change 50XXX
  • Status of base station 99

NB. these codes can be changed to users preference during manufacture.

The telephone patch functions, short code dial numbers, user access and security access codes can be reprogrammed over the telephone line without having to go to the remote site. The status of the base station (e.g. channel number, talkthrough on/off) will remain the same when the telephone line is cleared down, allowing the operator to enable or disable its use in a defined manner once the line is cleared down.
