10/100Base-T interface
CH.2 10/100BASE-T
LINK Indicator
Green indicator located in the CH.2 10/100BASE-T connector:
• Lights steadily when the LAN port detects the link integrity signal (normal
condition when there is no data activity)
• Off when the port does not detect the link integrity signal
CH.2 10/100BASE-T
ACT Indicator
Yellow indicator located in the CH.2 10/100BASE-T connector, flashes or lights
when the LAN port transmits or receives data (normal operating condition)
CH.2 10/100BASE-T
100M Indicator

• Lights steadily when the LAN port operates at a data rate of 100 Mbps
• Off when the LAN port operates at a data rate of 10 Mbps
E1/T1 MAIN Connector RJ-45 connector for connection to the main link interface
E1/T1 SUB Connector RJ-45 connector for connection to the optional sublink interface
CONTROL DCE Connector 9-pin female D-type connector for connection to the FCD-E1LC supervisory
terminal port

Function
Controls the sublink analog local loopback.
Controls the sublink analog remote loopback.
Controls the main link analog local loopback.
Controls the main link analog remote loopback.
To change the state of a loopback:
• To activate a loopback using this switch, set the corresponding switch
section to ON. The TST indicator on the front panel will light.
• To deactivate a loopback, return the switch to OFF. If no other test is active
on the FCD-E1LC, the TST indicator on the front panel will turn-off.
Note that the same activities can be performed by management (for example,
using the supervisory terminal). The actual state of a loopback is therefore
determined by the last command (either from the management or the switch).
