Release 4.0 Enhancements

Release 4.0 Enhancements
Release 4.0 includes all Release 3.1 functionality plus the enhancements listed
below:
Support for up to 200 stations
Release 4.0 has an expanded dial plan that supports up to 200 tip/ring
devices.
New 016 tip/ring module
This new module supports the 200 station dial plan by providing 16 ports
for tip/ring devices. Applications that use a tip/ring interface can connect
to this board. All 16 ports can ring simultaneously. Four touch-tone
receivers (TTRs) are included on the module as well. The module's
ringing frequency (default 20 Hz) can be changed through programming
to 25 Hz for those locations that require it.
Support for National ISDN BRI Service
This service provides a low-cost alternative to loop-start and ground-start
trunks for voice and digital data connectivity to the Central Office. Each
of the two B (bearer)- channels on a BRI line can carry one voice and
one data call at any given time. The data speeds on a B-channel are up
to 14.4 kbps for analog data and up to 64 kbps for digital data, which is
necessary for video conferencing and other video applications. Release
4.0 supports the IOC Package "S" (basic call handing) service
configuration and Multi-Line Hunt service configuration on designated
CO switches.
New 800 NI-BRI module
This new module connects NI-BRI trunks to the MERLIN LEGEND
system for high-speed data and video transmission.
