FRM220-FXO/FXS & FRM220-FXO/FXS-S
FXO/FXS POTS Over Fiber Optic
Slide-in-Module Media Converter
Description
CTC Union's FRM220-FXO/FXS POTS & FRM220-FXO/FXS-S over fiber media
converter connect 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/FXS & FRM220-FXO/FXS-S provide 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/FXS & FRM220-FXO/FXS-S are 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.
