2.3.2.1
Both SACCO-A are dedicated to work with the D-channel arbiter only. They must always
operate in “Transparent mode 0”.
For more details please refer to ELIC, PEB 20550, User’s Manual 1.96.
Neither SACCO-A are connected to any DOC pin.
2.3.2.2
The serial interface can be assigned by the PCM Signaling Multiplexer to 3 different
applications:
1. To any time-slot on the IOM-2 interface Port 0 to 3 in DD or DU direction
2. To the four PCM highways in DD or DU direction
3. As a stand-alone controller
Refer to Figure 2-24.
Semiconductor Group
In clock mode 0 are only the first 64 time-slots accessable.
