Boost Talk Battery and Current to
The TBB-1B will boost talk battery
voltage up to 48VDC, and current up
to 26mA on single analog line
extensions behind PABX's and
electronic key systems. This is
helpful for powering line powered
devices such as touch tone dialers
and emergency phones on low
voltage and/or low loop current
extensions.
When the TBB-1B is being used,
the power LED lights extra bright to

- Page 2 The TBB-1B is designed to boost talk battery voltage and loop current of a single analog line. The TBB-1B achieves this by creating its own 48VDC talk battery supply that is set up as a 26mA current source. An analog phone line can be in three different states: the idle state, the ringing state, and the in-use state.
- Page 3 Low idle voltage from a VoIP ATA, cable company or telco provided phone lines can cause some alarm panels to go into an alarm state. Solve this problem by wiring a TBB-1B as shown below. A TBB-1B increases the idle voltage, converting 24 volt lines to 48 volt lines.
