11.11.2 External High Order Alarm Indication (Ring) Port Interface
The external High Order Alarm Indication (Ring) Port Interface is necessary when sink and
source are processed on two different devices. The Receive High Order Path Ring Port /
Alarm Interface of the sink has to be connected to the Transmit High Order Path Ring Port /
Alarm Interface of the source and the external source mode has to be selected
(SelectExternalSource asserted).
Figure 40
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 High Order Alarm Indication (Ring) Port data frame.
The Receive High Order Alarm Indication (Ring) Port Interface consists of following leads:
The Transmit High Order Alarm Indication (Ring) Port Interface consists of following leads:
