1.3.3.3 – Connecting with MSP operation
As EOW and AUX ports are physically integral with ADR Optical, operating the order wire and
auxiliary channels with MSP protection requires the use of a "Y" cord electrically connecting, one
by one, identically, the signals of EOW and AUX connectors.

Likewise, in order to ensure a good behaviour during the changeover from one module to the
other, the operator should take care to keep identical configurations on both ADR Optical cards ;
in case of modification, automatic recopy is done and a warning message appears.
Only the connections are not identical. There must be no connections on the "Protection"
module, as in all the connections are made to the "Working" module.
