Figure 8-3 SUERSETDSS Module Configurations
The SUPH?SE~ DSS module is a member of the MITEL SUPERSET DN family of
telephones, and uses the DNIC interface. As with all SUPERSET DN devices the
module conforms to the evolving ISDN "U" interface format with two 64 kbs B channels
for voice or circuit-switched information, plus al6 kbs D channel for signalling
information.
Power for the SUPERSET DSS module is supplied by the PABX. All signalling and
power to the module is delivered over a single twisted pair from the DNI Line Card in
the PABX.
The SUPERSET DSS module interface operates in full duplex at 160 kbs. The module
only transmits its carrier after detecting carrier from the system. This prevents
transmission of a carrier signal into the network if the module is accidently plugged in
to an analog circuit.
