MCMG [SCA-4LC2COTA/MG-4LC2COTA]
MCMG [SCA-4LC2COTA/MG-4LC2COTA] has two functions, Media Converter (four lines) and Media Gate-
way (two lines). Media Converter (MC) is an interface providing media conversion between internet protocol
(LAN-side) and conventional voice data (the MC-connected conventional terminal-side). Media Gateway (MG)
is an interface between IP network and Analog PSTN line. Also two ports of MC will work as PFT ports when
a failure occurs. MC and MG usually work independently. In the case of some failure including IP link failure,
PFT connects C.O. line (MG side) and analog telephone (MC side) directly and provides emergency line.
