FRM220-FXO-4/FXS-4
4 x FXO/FXS POTS Over Fiber Optic
Slide-in-Module Media Converter
Description
CTC Union’s FRM220-FXO-4/FXS-4 POTS over fiber media converter connects
central-office voice grade signal to distant POTS (Plain Old Telephone Service) equipment
using standard telephone signaling. It can extend, over fiber, the distance between two
voice path communication devices by up to 120km using single mode fiber.
The FRM220-FXO-4/FXS-4 provides audio transmission, caller ID, ringing at the distant
end and automatic ring down. Two units are required to implement an end to end system.
The RJ-11 connector provides the electrical interface between the media converter and the
telephone device or PSTN.
The FRM220-FXO-4/FXS-4 is designed to be installed in FRM220-CH20 (20 slots Chassis)
for CO side or installed in FRM220-CH01 (1 slot Chassis) for CPE stand-alone.
