UNIT SERVICE STATE
When selecting In-Service, Traps reporting is Enabled. If Out-of-Service is
selected, Traps reporting is disabled. A Trap is sent when the status is
changed from Enabled/Disabled or Disabled/Enabled.
E1 PORT EQUIPMENT
Within each E1 port setup, the state of the port can be set to Equip or Mot-
equipped. When set to Mot-equipped, the end user has the ability to perform
maintenance on the line without impacting the other parts on the module.
LOOPBACK
Each E1 port can be tested in loopback mode by enabling either a Host
loopback or Remote loopback test path. This capability allows the end-user to
help troubleshoot and isolate system problems such as improper/broken line
terminations, cables or malfunctioning equipment.
With Host loopback, the E1 copper port, connected to the Host unit, is looped
back to that port within the local unit. E1 data coming from the remote unit to
that port over the optical link is also looped back to the remote unit at the
same point within the local unit.
With remote loopback, an E1 line connected to the Host unit is transported on
the optical link and looped back within the remote unit back onto the optical
link without passing onto the copper E1 line of the remote unit. The remote’s
incoming E1 copper line is also looped back to the copper line within the
remote unit.
The default value for loopback is "none."
