Page 808 of 894 NTDK20 Small System Controller card
553-3001-211 Standard 2.00 September 2004
SDI ports
The NTDK20 SSC card in both the Call Server and the MG 1000S systems
contains three SDI ports used to connect on-site terminals or remote terminals
through a modem. Table 255 shows the port default settings.
Conferencing
Thirty-two conference channels are provided by the NTDK20 SSC card’s
conference devices. Conference capability can be increased by mounting
expansion daughterboards on the NTDK20 SSC card. Each dual IP
daughterboard increases the total number of conference channels by 32. The
maximum number of conference ports is 96.
Each conference device provides 32 ports of conferencing capabilities (one
conference participant for each port). A conference call can have three to six
participants. For example, there could be six 5-party conferences on each
device, or four 6-party conferences plus two 3-party conferences. It is not
possible to conference between conference devices.
10BaseT port
The Call Server provides one 10BaseT connection to a Local Area Network
(LAN) to interface with Management software applications such as OTM and
CallPilot. The MG 1000S SSC 10BaseT port, Port 1, is disabled by default.
To use the 10BaseT port, the port must be assigned a unique IP address and
the port must be enabled from the Call Server.
