CAUTION:
Care must be used at the cross-connect bay because traffic is being
carried on the DSs from the low speed shelf - system controller. At this
time, traffic is not on the protection access shelf.

etc.), loop back only the low-speed circuits that are associated with protection
access. Do not use the FAULT-Operate-Loopback command at the
FT-2000 network element. Loopback is toward the FT-2000 network element.

unsuccessful test.
17. Does report indicate "g" for good or "-" for not tested for each entry?
