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