Transition Stand-Alone - media converter

The Transition POTS phone line converter system is intended to connect central-office voice grade signals to distant Plain old telephone equipment (POTS) utilizing standard telephone signaling. Two units are required to implement an end to end system; Unit A connects to a telephone line or PBX and has the ability to detect ringing voltages and to act as a telephone (Line Side FXS). Unit B is the reciprocal unit and has the ability to act as a Central Office and connects to a telephone device (Customer Side FXO).

The Transition Networks SAPTF3315-110 copper to fiber converter system provides audio transmission, caller ID, and ringing at the distant end. The electrical interface is provided through a RJ-11 female connector. Automatic ring-down is accomplished when two "B" (FXO) units are connected to each other.
