4-10 Access System Centum Series User Manual
Serial Port Loop
Local Loop ON causes a loop (at the Centum Series unit where the
command was entered). Remote Loop ON causes a loop at the Serial Port
at the distant end. In an Integrated Access, Fractional T1 environment,
the Serial Port #1 and Serial Port #2 links through the network is a logical
point-to-point connection and the “distant end” is the destination for the
serial port data.
CAUTION
Local and Remote Loops should not be activated at the same time
unless the serial port BERT is also activated at the local end. (See
Serial Port BERT, on page 4-12).
WHEN TESTING IS COMPLETED, BE SURE TO TURN THE LOOP
“OFF”.
