SDI ports.
Conferencing
Thirty-two conference cha nnels are provided by the NTDK 20 SSC card’s
conference devices. Conference capability can be increased by mounting
expansion daughterboards on the NTDK20 SSC card. Each daughterboard
increases the total number of conference channels by 16: the maximum
number of conference ports is 64.
Each conference device provides 16 ports of conferencing capabilities (one
conference participan t for each port). A conferen ce call can have three to six
participants. To illustrate, you can have a maximum of five 3-party
conferences for each device, or two 6-party conferences plus one 3-party
conference. It is not possible to conference between conference devices.
IP expansion 10BaseT port
The Option 11C system provides one 10 Mbps Ethernet connection to a Local
Area Network (LAN). The 10BaseT Ethernet port available on the SSC of an
IP Expansion cabinet is functional. However, the Ethernet port on the IP
Expansion cabinet does not have a default IP configuration. This means that
the IP port configuration must be performed before it can be used.
It is not recommended to use the remote 10BaseT port in normal mode as
maintenance or alarm management are not available. In survival mode it
assumes the system level configuration of the main cabinet port.
