You have finished monitoring the circuit.
The HST-3000 allows you to monitor the timing between two
E1 signals for timing slips. For example, you can check
customer premises equipment against a master clock at the
central office, or you can compare two lines of network equip-
ment. The HST-3000 measures the difference, in bits per
second (bit/s), between the opposite receiver (Rx) or the
external 2M Reference clock.
