MG(PRI) (1.5M) [SCA-24PRIA/MG-24PRIA]
MG(PRI) [SCA-24PRIA/MG-24PRIA] is a media gateway between ISDN network and IP network to provide
a Primary Rate Interface (T1) through interaction with the system. MG(PRI) is controlled by the Telephony
Server, and a variety of services can be performed.
MG(PRI) (2M) [SCA-30PRIA/MG-30PRIA]
MG(PRI) [SCA-30PRIA/MG-30PRIA] is a media gateway between ISDN network and IP network to provide
a Primary Rate Interface (E1) through interaction with the system. MG(PRI) is controlled by the Telephony
Server, and a variety of services can be performed.
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.
MG-SIP16 [SCA-16SIPMGA/MG-16SIPMGA]
MG-SIP16 [SCA-16SIPMGA/MG-16SIPMGA] is an Media Gateway to provide the system with Session Initi-
ation Protocol (SIP) interface. It enables the system to build a multi-service and reliable Voice over IP (VoIP)
networks using SIP defined by IETF. Up to 16 channels of extensions in the network can communicate with
outside SIP network via an MG-SIP16 at the same time. As MG-SIP16 complies with small and middle sized
remote offices flexibly, more offices can profit Peer-to-Peer VoIP services using IP station.
