SDSL Router Controller Unit (1200377L1 and 1200377L2)

The following is operational information pertaining to the SDSL Router Controller Unit when used with

the Total Access 850 system.

Faceplate CRAFT Interface

Use the CRAFT port on the RCU faceplate to configure the system via an EIA-232 connection. Table 7

displays the

CRAFT port pinout.

Faceplate LEDs

The faceplate LEDs provide status information using a color coded message format. Table 8 gives a

description of all faceplate LEDs for the SDSL RCU when used with the Total Access 850 system.
