INTRODUCTION
INT-22
IPPAD (PA-32IPLB)
IPPAD is a gateway interface card that is automatically used when an IP station attempts to make/receive a call
to/from a station and TRK accommodated in PIR. One IPPAD can control a maximum of 32 calls. Refer to the
Circuit Card Description for more details. This card is required when PIR is accommodated in the Telephony
Server.
H.323 Terminals
H.323 terminal is a station that uses H.323 protocol as the communication protocol. The system supports this
H.323 terminal.
Analog 2MC
Analog 2MC is a gateway device providing media conversion between Internet Protocol (LAN-side) and con-
ventional Voice Data (the MC-connected conventional terminal-side). By using this converter, legacy analog
telephones can serve as IP stations under the control of the Telephony Server. A maximum of two analog ter-
minals including a FAX can be connected.
MC & MG with PFT
MC & MG with PFT consists of Analog MC and Analog MG (COT). A maximum of four analog terminals and
two analog C.O. lines can be connected. In case of commercial power outage, the built-in PFT is activated to
connect analog C.O. lines and analog terminals directly. Thus analog terminals can place/receive a call to/from
Public Network.
MG-BRI
Media Gateway - Basic Rate Interface (MG-BRI) provides the Gateway function for ISDN network and IP net-
work and it is available to accommodate a maximum of two ISDN lines. MG-BRI also can connect one emer-
gency telephone line to be used in case MG function of the equipment is not available because of power failure
or IP network failure. In this case, emergency telephone will be automatically connected to the ISDN network
and provides the communication path.
