Call Route Entry Counters - Field Definitions

Description

The description of the Call Route Entry as is appears in its parent Call Route Table.

Admin State

Indicates whether or not the entry is in an Enabled or Disabled State. For information about enabling and disabling entries, see Adding and Modifying Entries to Call Routing Tables.

Usage Count

Displays a count of how many times this route has been used.

Quality Metrics

Displays the average call quality for this call route.

ASR

Displays the Answer/Seizure Ratio for this call route.

The ASR is a measure of network quality defined by the ITU. The answer/seizure ratio (ASR) is a measurement of network quality and call success rate in telecommunications. It is the percentage of answered telephone calls with respect to the total call volume.

The answer/seizure ratio is defined as 100 times the ratio of sucessfully answered calls divided by the total number of call attempts (seizures).

Busy signals and other rejections by the called number count as call failures. This makes the ASR highly dependent on end-user action or behavior and is out of control by the telecommunications carrier. Low ASR values may be caused by far-end switch congestion, not answering by called parties and busy destination lines.

MOS

Displays the Mean Opinion Score for this call route.

Round Trip Delay

Ddisplays the average round trip delay for this call route.

In telecommunications, the round-trip delay time (RTD) or round-trip time (RTT) is the length of time it takes for a signal to be sent plus the length of time it takes for an acknowledgment of that signal to be received. This time delay therefore consists of the transmission times between the two points of a signal.

Jitter(ms)

Displays the average jitter for this call route.
