Line Testing (Integrated Access, Fractional T1)
The line testing can be performed via either Acce ss System56 control
panel or an external terminal or PC. The instructions below assume that
the unit’s control panel is being used. Chapte r6, Auxiliary Ports,
describes usage of an external terminal.
The line itself cannot be tested directly in an Integrated Access,
Fractional T1 environment (the Network remote loop will not function). It
can, however, be tested indirectly by using the Serial Port channel. If a
Serial Port channel is being used, Remote Loop must be enabled for all
Access Syst em56 units at remote locations.
Use SELECT and the UP and DOWN arrows to choose Serial Port.
Use SELECT and the UP and DOWN arrows to choose Remote Loop On
or Local Loop On (but not both). 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 Serial Port destination.
Turn Off the BERT and the Loop. Your system is now ready for
operation.
