Bridge Status on Remote Port Interface

This color-coded text box indicates the operating status of the remote port.

Possible status conditions are:

¥LINK OK/DCE READY (green) Ñ Indicates that communication between the remote port and the data circuit-terminating equipment (DCE) is established and ready to transfer data.

¥NET LOOP/LINK OK (green) Ñ Indicates that the port is looped towards the network and that the port is ready for transmission.

¥NET LOOP/LINK LOST (blue) Ñ Indicates that the remote port, looped towards the network, is not receiving any signal.

¥NET LOOP/RED ALARM (red) Ñ Indicates that the remote port, looped towards the network, has lost synchronization on the bridgeÕs receive link.

¥NET LOOP/YELLOW ALARM (yellow) Ñ Indicates that the remote portÕs loop towards the network has lost synchronization on the remote bridgeÕs receive link (i.e., the remote bridge on the other side of the link is in Red Alarm condition).

¥REM LOOP/LINK OK (green) Ñ Indicates that the port is performing a remote loopback test and that the port is ready for transmission.

¥REM LOOP/LINK LOST (blue) Ñ Indicates that the port performing a remote loopback test is not receiving any signal.

¥REM LOOP/RED ALARM (red) Ñ Indicates that the port performing a remote loopback test has lost synchronization on the bridgeÕs receive link.

¥REM LOOP/YELLOW ALARM (yellow) Ñ Indicates that the port performing a remote loopback test has lost synchronization on the remote bridgeÕs receive link (i.e., the remote bridge on the other side of the link is in Red Alarm condition).

¥NORMAL /LINK OK (green) Ñ Indicates that the port is in normal T1 Link operation and is ready for transmission.

¥NORMAL /LINK LOST (blue) Ñ Indicates that the port, in normal T1 Link operation, is not receiving any signal.

¥NORMAL /RED ALARM (red) Ñ Indicates that the port, in normal T1 Link operation, has lost synchronization on the bridgeÕs receive link.

¥NORMAL /YELLOW ALARM (yellow) Ñ Indicates that the port, in normal T1 Link operation, has lost synchronization on the remote bridgeÕs receive link (i.e., the remote bridge on the other side of the link is in Red Alarm condition).

¥DCE NOT READY/NO DM (blue) Ñ Indicates that the DCE is not in the data transfer mode.

¥DCE NOT READY/NO CTS (blue) Ñ Indicates that the DCE is not ready to transmit data.
