Data Sheet
After a reset, or in power down there is no communication via the PCM highways. Also
when selecting new timeslots it is recommended to switch off the PCM line drivers by
setting the control bits to zero.
This is the normal operating mode without conferencing. Only the channels R1 and
X1 are in use, and voice data are transferred from subscriber A to analog subscriber
S and vice versa.
In this mode the SLICOFI-2 acts as a server for a three-party conference of
subscribers B, C and D which may be controlled by any device connected to the PCM
highways. The SLICOFI-2 channel itself can remain in power down mode to lower
power consumption.
Like in External Conference mode any external three-party conference is supported.
At the same time an internal phone call is active using the channels R1 and X1.
If the analog subscriber S is one of the conference partners, the internal conference
mode will be selected. The partners (B, C) do not need any conference facility, since
the SLICOFI-2 performs all required functions for them as well.
