ACTIX REPORTING TERMS

Accessibility Percentage of call attempts that resulted in a successful call initiation

Retainability Percentage of successfully initiated calls that did not drop until callcompletion

Voice Quality Audio quality during calls placed throughout a carrier¶s network.Percentage of combined uplink and downlink MOS samples that are

greater than or equal to a threshold

RxQUAL Received signal quality level, measured base on BER (bit error rate).Value is between 0-7, the lower the better.

RxLEV BTS and MS measure the received signal level within the range of í110dBm to í48 dBm. Measured signal levels are averaged and mapped to

RXLEV (received level) values, which are between 0 and 63.

Mean-Opinion

Score (MOS)

Provides a technology-independent, objective score of the audio/voice

quality of a call on an operator¶s network. Higher the MOS value, better would be the quality

EcNo Ratio between the received energy per chip divided by the power density

in the band. 'No' includes the power of specified cell as it indicates totalreceive power

RSSI Received Signal Strength Indicator is a measurement of the power presentin a received radio signal.

RSCP Received Signal Code Power is the power measured by a receiver on a particular physical communication channel. Used as an indication of

signal strength, as a handover criterion, in downlink power control, and tocalculate path loss. In CDMA systems, a physical channel corresponds to

a particular spreading code, hence the name.

Congestion Occurs due to non-availability of a traffic channel (TCH) or SDCCH to

the mobile due to capacity shortage, non-availability of circuit or switching circuit.

Access Time Time elapsed from the time the Send button is pressed to the time whenthe connect acknowledgment message is received at the mobile i.e. the

three-way handshake is completed.

Call Attempt Demand by a user for a connection to another user. Occurs when a mobileradio initiates a call sequence to obtain a voice channel, whether or not asystem control channel is available.

Access Failure Occurs when the user fails to obtain a traffic channel after a call attempt ismade

Access Timeout

failure

Occurs when the user fails to obtain a traffic channel within a specific

time period (30 sec) after a call attempt is made

Assignment Failure Occurs when the user fails to lock onto the assigned channel even after the
