Using TST TS0s for testing can be very useful, particularly in Frac-
tional E1 applications. You can run an end-to-end test on the Frac-
tional TS0s by 1) setting for Map B the TST in the same TS0 as used
by Map A to receive data from an Nx56/64 port and 2) by looping
the far end using a V.54 loopback code on the Nx56/64 port. In
addition, a single TS0 can be used for continuous testing while
other TS0s are passing normal data. This will also provide an end
to end check on the entire link. Set each end to send QRSS in TST
TS0s (using 1 TS0) and occasionally view the results on the Pattern
Result menu selection.
