G.772 Performance Monitoring
The LXT384 can be configured as an octal line interface unit with all channels working as regular
transceivers. In applications using only seven channels, the eighth channel can be configured to
monitor any of the remaining channels inputs or outputs. The monitoring is non-intrusive per ITU-
T G.772.
Figure 1 on page 7
illustrates this concept.
