If no fault is found, the entire OC-N circuit path has now passed its comprehensive series of loopback
tests. This circuit qualifies to carry live traffic.
1.4 Troubleshooting Wideband Electrical Card(WBE-28 and
WBE-84 Cards) FEAC on DS3 Ports
WBE-28/WBE-84 cards support far-end alarm and control(FEAC) functions on DS3 ports. Click the
WBE-28/WBE-84 Maintenance > DS3 tabs at the card view to reveal the two additional function
columns. Figure 1-1 shows the DS3 subtab and the additional Send Code and Inhibit FE Lbk function
columns.
Figure 1-3 Accessing FEAC Functions on the DS3 ports of WBE-28/WBE-84 Cards
The "far end" in FEAC refers to the equipment connected to the WBE card and not to the far end of a
circuit. In Figure 1-2, if a WBE-28/WBE-84 DS3 (near-end) port is configured to send a line loop code,
the code will be sent to the connected test set, not the WBE-28/WBE-84 DS3 (far-end) port. FEAC
functions will be available only when the DS3 port is configured in CBIT Framing.
