| FAQ |
There is not a day that goes by when ClearSight's technical support is asked about
technologies involving our products. We have listed a few of these questions and
accompanying answers to see what interest other ClearSight customers. If you have
a question that you would like to see answered in a future edition of the newsletter,
please write us at marketing@clearsightnet.com
How does the ClearSight Analyzer recognize what type
of call was made? in other words, whether it was a local, intercom, long distance or international call?
ClearSight analyzer software determines the origin of the call by
checking the number of digits in the telephone number. A length of
less than 7 digits suggest it is an intra-office call; exacty 7
digits mean it is a local call. A long distance call has 11 or few
digits and an international call has more than 11 digits.
How is 'Call Quality' defined in the SIP Call Summary
reports?
'Call Quality' is a numerical representation of a range of MOS
(Mean Opinion Score) values. Calls that are classified as a good have a
MOS value of greater than 4.34. Calls with MOS values of less than or
equal to 4.34 but greater or equal to 3.60 are identified as acceptable.
Poor quality calls typically have MOS values of less than 3.60.
| MOS |
Call Quality |
| Greater than 4.34 |
Good |
| between 3.60 and 4.34 |
Acceptable |
| less than 3.60 |
Poor |
What are the various RAID levels as they relate to the Network Time Machine product?
RAID, short for Redundant Arrays of Independent Disks, is a technology that
supports the integrated use of multiple of hard disk drives
used in order to achieve greater performance than what can
otherwise be had through single drives. RAID technology can
also protect the integrity of data stored on disk drives.
The ClearSight Network Time Machine uses of RAID 0 and 5
in its long term network capture and storage solutions offering
a high level of performance and data protection
(for the RAID 5 configuration).
RAID 5: Level 5 : Distributed Parity
RAID 4: Level 4 : Dedicated Parity Drive
RAID 3: Level 3 : Bit-Interleaved Parity
RAID 2: Level 2 : Error-Correcting Coding
RAID 1: Level 1 : Mirroring
RAID 0: Level 0 : Striped Disk Array without fault tolerance
What is the easilest way to restart the Network Time Machine agent?
The NTM Manager/ Viewer can restart the NTM agent. |
