Figure 1-18 Accessing FEAC Functions on the DS3XM-6 Card
The "far end" in FEAC refers to the equipment connected to the DS3XM-6 card and not to the far end
of a circuit. In
code will be sent to the connected test set, not the DS3XM-6 (far-end) port.

1.4.1 FEAC Send Code
The Send Code column on the DS3XM-6 card Maintenance tab only applies to out-of-service (OOS_MT,
OOS_AINS) ports configured for CBIT framing. The column lets a user select No Code (the default) or
Line Loop Code. Selecting Line Loop Code inserts a line loop activate FEAC in the CBIT overhead
transmitting to the connected facility (line). This code initiates a loopback from the facility to the
ONS 15454. Selecting No Code sends a line-loop-deactivate FEAC code to the connected equipment,
which will remove the loopback. You can also insert a FEAC for the 28 individual DS-1 circuits
transmuxed into a DS-3 circuit.
