What is 8LC Card?

8LC Card is a Media Converter (MC), providing 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 system. Media Data (voice/fax) is
sent/received directly between IP terminals (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 communicate by directly sending conventional Media Data (voice/fax) to
MC. MC embeds the media in IP packets, which are sent to the destination IP terminals on the LAN.
Control signal between the Telephony Server and 8LC Card is handled by SP-PHI, which is embedded function
of the Telephony Server to use Session Initiation Protocol (SIP), and control signal and voice packets are en-
crypted to ensure security feature.
