The Interface C gs command shows whether the link to the Ethernet is
operational and whether the PHY has connected properly. Check your settings if
this status report shows that there are problems.
4.
Confirm that the configuration of the G1600 pair is compatible and consistent.
See “Configuring a Pair of G1600s” on Chapter 1. The CES GetStatus (gs)
command shows whether there is connectivity with the peer G1600 and the peer
is reachable.
5. It is recommended to set one G1600 as Loopback-Master and the other as
Recovered-Slave. If the Tx clocks on both G1600s are configured as
Loopback-Master, make sure that the clock source driving both units is stable.
Operating both units as Slave is not recommended and may produce
unpredictable results.
6. Use an E1 tester to perform the remote loopback test.
