Each MG 1000E provides up to 64 conference circuits (ports), which
can be used to form conferences of up to 30 parties each. Conferences
are restricted to 6 parties each when using SSC. The MGC card has 60
conference circuits (2 loops). The SSC card has 32 conference circuits
(2 loops), and another 32 conference circuits (2 loops) on the dual-port
IP daughterboard. Users can configure 2 conference loops on each
MGC-based MG 1000E, with each loop providing 30 conference circuits.
Users can configure 4 conference loops on each SSC-based MG 1000E,
with each loop providing 16 conference circuits.
The conference circuits are available to all MG 1000Es in the system.
Calls are assigned to conference circuits on a "round robin" basis. Each
conference circuit is accessed through a DSP port in the MG 1000E that
the conference loop is defined. In addition, the device using the service
can require another DSP in order to reach the conference port
