OC-48 facility loopback testing
Facility Loopback testing allows the installer to verify cabling to the OC-48 equipment.
This test is only required if the 1665 DMX shelf is connected to OC-48 equipment. If the
shelf is NOT connected to OC-48 equipment, skip this section and continue to the next
chapter.
Important!
An optical test set with the capability to transmit OC-48 SONET levels
are necessary for the testing.
The Function Unit slot under test must contain an OC-48 (LNW31, LNW425, LNW427,
LNW447, LNW449, LNW453, LNW455, LNW459) circuit pack in order to perform this
test.
