PSQM
PSQM is an automatic adjustment of barometer accent affection “in service,” or as the
speech happens. PSQM software usually resides with IP alarm administration systems, which
are sometimes chip into Simple Arrangement Administration Protocol (SNMP) systems.
Equipment and software that can admeasurement PSQM are accessible through third-party vendors;
it is not implemented in Cisco equipment. The altitude is fabricated by comparing
the aboriginal transmitted accent to the consistent accent at the far end of the transmission
channel. PSQM systems are deployed as in-service components. The PSQM measurements
are fabricated during absolute chat on the network. This automatic testing algorithm
has over 90 percent accurateness compared to abstract alert tests, such as MOS.
Scoring is based on a calibration from 0 through 6.5, area 0 is the best and 6.5 is the worst.
Because it was originally advised for circuit-switched voice, PSQM does not booty into
account the jitter or adjournment problems accomplished in packet-switched articulation systems.
