Mg-Cot Card [Sca-6Cota/Sca-6Cotb]; Mcmg Card [Sca-7Cota]; 8Lc Card - NEC Univerge sv8500 Manual

MG-COT Card [SCA-6COTA/SCA-6COTB]

MG-COT Card [SCA-6COTA/SCA-6COTB] has a function of Media Gateway (MG) which is an interface be-
tween IP network and Analog PSTN line. Also an analog telephone 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 (MG side) and analog telephone (PFT side) directly and provides
emergency line.

MCMG Card [SCA-7COTA]

MCMG Card [SCA-7COTA] has two functions, Media Converter (one line) and Media Gateway (seven 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 MC part will work as PFT port 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.
8LC Card [SCA-8LCA/SCA-8LCA-EMEA/SCA-8LCC/SCA-8LCC-EMEA]
8LC Card [SCA-8LCA/SCA-8LCA-EMEA/SCA-8LCC/SCA-8LCC-EMEA] is a Media Converter (MC), pro-
viding media converting function between Internet Protocol (LAN-side) and conventional Voice Data (MC-
connected conventional terminal side). By using this converter, analog telephones can serve as IP stations under
the control of the Telephony Server. Media Data (voice/fax) is sent/received directly between IP devices/sta-
tions (MC-to-MC, MC-to-DtermIP, etc.) in Peer-to-Peer connection. 8LC Card has eight analog ports (modular
jacks). Analog telephone and fax can be connected to the analog ports. The MC-connected terminals communi-
cate by directly sending conventional Media Data (voice/fax) to MC. MC embeds the media in IP packets, which
are sent to the destination IP devices/stations on the LAN.
