The line data communication module (LDCM) is used for communication between the IEDs
situated at distances <68 miles or from the IED to optical to electrical converter with G.703
interface located on a distances <1.9 miles away. The LDCM module sends and rereceives data, to
and from another LDCM module. The IEEE/ANSI standard format is used.
The line data communication module is used for binary signal transfer. The module has one optical
port with ST connectors see figure 663 .
