Tracking
Tracking is an option that prevents calls from being left out of archives. Because
of the inherent nature of the technology involved, NexLog Recorders do not
always receive calls from VoIP and Centralized Archiving sources in real-time.
They can, under certain conditions, end up receiving calls hours or even days
after they were originally recorded. This can have a significant impact on
archiving. Take the following scenario for example:
A busy NexLog Recorder with both local input board sources and VoIP
channels.
The archive pointer on a DVD-RAM drive is set to current time.
Calls are currently coming in on the local input channels.
Due to temporary but severe network congestion, the VoIP Gateway has
buffered an hour’s worth of calls, which is just now transferring to the
NexLog Recorder.
Starting to archive calls to this DVD-RAM drive would leave the hour of VoIP
calls unarchived. Because of this, archive drives can optionally be set to wait for
remote data, which will prevent any archive from writing past the current
archive time of any source that is not currently up-to-date.
In the same scenario as the preceding one, but with Tracking turned on, the
result would be the DVD-RAM drive would pause in archiving mode, idle, until
the VoIP system caught up to the archive time that had been initially set, at
which point the DVD-RAM would begin to fill with all of the calls, leaving
nothing unarchived.
This feature is optional only because a Call Source may be temporarily off-line
and one needs to archive calls anyway. In that case, turn off CST, create the
archive you need, then turn CST back on and reset the archive time.
4.7.3. Media Selection
This section assumes you are using DVD-RAM disks for archiving
. Eventide
recommends any of the following configurations of media for DVD-RAM
archiving:
For NexLog recorders equipped with the older Panasonic SW-9576 DVD-RAM
drives, use the following media type:
PANASONIC 9.4 GB DVD-RAM, double-sided media, inside a Type 2
or Type 4 cassette. The cartridge will need to be flipped to use the
2
nd
side.
