11.9.2 External Line Alarm Indication (Ring) Port Interface
The external Line Alarm Indication (Ring) Port Interface is necessary when sink and source
are processed on two different devices. The Receive Line Ring Port / Alarm Interface of the
sink has to be connected to the Transmit Line Ring Port / Alarm Interface of the source and
the external source mode has to be selected (ExternalSourceSelect asserted).
Figure 42
The external interface consists of a clock, data and start of frame line. A start of frame pulse
coincides with the first bit of the Line Alarm Indication (Ring) Port data frame.
The Receive Line Alarm Indication (Ring) Port Interface consists of following leads:
The Transmit Line Alarm Indication (Ring) Port Interface consists of following leads:
