does not add additional delays. This means that the priority management on the S
(two classes) still may be used, allowing the mixture of signaling and packet data.
Nevertheless, it still can make sense to use the ELIC arbiter in this configuration. The
advantage of using the arbiter is, that if one terminal fails the others will not be blocked.

The SIDEC is a 4-channel signaling controller containing slightly modified SACCO
modules and a control logic for DRDY handling (Stop/Go signal from QUAT-S).
Figure 2-22 SIDEC Block Diagram
Depending on the DRDY signal from QUAT-S (in LT-T mode) the SIDECn sends data in
the programmed time-slot or waits for a “Go” signal, Figure 2-22 and Figure 2-23.
