Verilink PRISM 3001 (34-00186) Product Manual - Manual (Page 6)

1-2 G ENERAL
The unit may be controlled through a VT100 terminal or a computer with ANSI
terminal emulation software. If used with the EM8000 Element Manager or 8100A
Site Controller, the entire T1 network can be monitored and controlled from a
central location.
LED indicators are provided on the front panel of the unit to alert local personnel
of alarm conditions, loop and test status, and DTE port activity. A test switch
allows local and remote loops to be activated as well as BERT tests. Although all
configuration parameters are software selectable from the terminal interface or the
network manager, configuration switches are provided on the unit to allow
operation without the use of a management interface.
