106 CHAPTER 2: DIAL PLAN
Table 20 Virtual Tie Line Statistics Fields
Field Description
NOTE: All statistics apply to the time period since the most recent Reset command
or since the most recent system reboot, whichever was more recent. To determine
the starting time for the displayed statistics, compare the Last reset command with
the time of the Last system reboot. Both are displayed at the bottom of the VTL
Statistics window.
Number of outgoing
VTL calls made
The number of outgoing calls made over all virtual tie lines
(VTLs) since the most recent reset command or since the time
the NBX system was last restarted. Each time you restart the
NBX system, you reset the statistics for all VTLs.
Number of incoming
VTL calls received
The number of incoming calls received over all VTLs since the
most recent reset command or since the time the NBX
system was last restarted.
Number of active VTL
calls
The number of calls currently active on all VTLs.
Maximum number of
concurrently active
VTL calls
The maximum number of VTL calls that have been active at
the same time on this NBX system since the most recent
reset command or since the time the NBX system was last
restarted.
Incoming VTL calls
rejected due to all
VTLs busy
The number of telephone calls that would have arrived from
other NBX systems over VTL channels, but could not be
accepted because all local VTL ports were busy when the
calls arrived.
Outgoing VTL calls
rejected due to all
VTLs busy
The number of telephone calls that would have been sent
from the local NBX system over VTL channels, but could not
be sent because all local VTL ports were busy when the calls
were made.
Rerouted VTL calls The number of calls that did not reach their destination
when attempted over VTL channels, and were rerouted using
another device.
Last reset command The date and time of the most recent Reset for this VTL.
Last system reboot The date and time of the most recent reboot of the NBX
system.
