STM-1 Receiver Monitor Input (Special Option 808)
Specification
Description
A fixed attenuator and a special cable attenuator are inserted between the STM-1
OUT port and the STM-1 IN port. The Receiver monitor mode is verified by
attenuating the signal by 20dB, along with the cable attenuator, and checking for
error-free operation.
