Note: The CDM-710G supports Simplex (Tx Only or Rx Only) operation; Duplex (Tx/Rx)
operation; and 1:1 or 1:N redundant operation.
The European EMC Directive (EN55022, EN50082-1) requires using properly shielded cables for
DATA I/O. These cables are double-shielded from end-to-end, ensuring a continuous ground
shield.
Table 4-1 summarizes the connectors provided on the CDM-710G rear panel. Refer to the
applicable Data Interface chapter in this manual for information on, and connector pinouts for, the
available G.703, HSSI, and GigE Data Interfaces.
