Line Testing (Integrated Access, Fractional T1)
The line testing can be performed via either Centum Series control panel
or an external terminal or PC. The instructions below assume that
Centum Series control panel is being used. Chapter 6 , Auxiliary Ports,
describes usage of an external terminal.
The line itself cannot be tested directly in an Integrated Access,
Fractional T1 environment (the NI remote loop will not function). It can,
however, be tested indirectly by using the Serial Port channel.
If any locations are served by DSX channels (and only DSX channels),
the PBX units must be connected and used to test the links to those
locations.
Use SELECT and the UP and DOWN arrows to choose Serial Port #1
Remote Loop On. Then, use the UP/DOWN arrows and SELECT to turn
on the BERT. Finally, use the arrows to confirm that Seconds/Test is
incrementing but Local and Remote Errored Seconds is not incrementing.
This checks out the link from the local site to the ultimate Ser ial Port#1
destination.
Turn Off the BERT and the Loop. Your system is now ready for
operation.
