Viking Electronics’ TBB-1B is an in-line device that actively boosts talk battery power to analog devices.
“It’s getting more common that FXS ports and analog extensions don’t produce enough talk battery. The TBB-1B solves this problem and it is simple to use.” Paul Speltz, Sr. Engineer, Viking Electronics
TBB-1B talk battery booster
Use the TBB-1B to boost talk battery from a VoIP phone system ATA with an FXS port, an analog PABX extension, a VoIP cable modem, a POTS line and more. The incoming under powered line is connected to the TBB-1B where talk battery voltage is boosted to 48V DC. The line with boosted talk battery now travels from the TBB-1B to the analog device.
Analog devices that can benefit from the use of the TBB-1B include elevator phones, emergency and area of refuge phones, alarm panels, door entry phones, and traditional analog telephones.
