Figure 2-23 SIDEC Signals
The DRDY signal is latched internally using a timeslot indication signal TxCLKx and
switches the transmission on/off via the CTSx pins.
A “Stop” forces the affected channel to abort the HDLC frame; upon a “Go” the affected
channel restarts the frame.
2.3
As the DOC contains two independent switches and eight different HDLC controllers,
multiple programmable (multimode) multiplexers are implemented (Figure 2-24):
• An IOM-Ports multiplexer
• A PCM-Ports multiplexer
• IOM and PCM signaling multiplexers
• An ELIC1-Port multiplexer
