10.1 General
10.1.1 What is MG-COT?
MG-COT has a function of Media Gateway (MG) which is an interface between IP network and Analog PSTN
line. Also an analog terminal for exclusive use of Power Failure Transfer (PFT) can be connected through a PFT
connector on this card.
MG usually works independently. In the case of failure of MG-COT, PFT connects C.O. line and analog termi-
nal directly and provides emergency line.
Note
Note:
For the PFT service on the UG50, a station line connected to the PFT port cannot be used as a station line
for the system. Be sure to connect a terminal that can be used as telephone to the PFT port. Terminals such
as a FAX terminal are not allowed.
