4.2.4.4 E1 Signal Status
Each RPC can have 4 E1 lines to communicate with the WLL/V5WLL.
However, the D-channel can be established on only one E1 line. The E1 line on
which the D-channel is established is named the master E1 and the other three E1
lines are named slave E1s. If the master E1 line is down, a slave E1 line will be
promoted by the system to become the master E1. The D-channel can be
established on this slave E1 line. The selection of the master E1 follows the
round-robin order.
Use the E1 Signal option to monitor and verify the operational status of the E1
signal, including four E1 interfaces, E1 warning, Layers 1 through 3, and other
status information.
1. From the Status main menu, select Status, and then E1 Signal. The E1
Signal Status window appears on the right frame of the RPC window, as
shown in the figure below. Another way to open the window is to click the
E1 Status button.
