Figure 3 Meridian SL-100 system architecture
The S71 is programmed to enable interrupts on its two transceivers. Both
transceivers of the S71 are used, subject to the link open and close state of
each. This feature supports transmission and reception of DMSX messages
over one or both DMSX links simultaneously and handles error conditions.
The controller card also provides an overload control processing function that
sends the XPM information regarding the state of the IPE messaging memory
usage.
Messages to analog sets are translated from DMSX format to A10 format.
Messages from analog sets are translated from A10 format to DMSX format
and are sent to the XPM.
