separately.

Note: 18 neighbor cells are present. The first neighbor cell band class is

 

 

0, its PilotPN is 268, and its frequency assignment is 384.

The value displayed for Ec/Io is the index of the Active set in 0.5dB steps from 0 (0dB) to 63 (-31.5dB). For example: 0 = 0dB, 1 = 0.5dB, 2 = 1dB, … 62 = 31dB, 63 = 31.5dB

If the <requested dump> parameter is not specified, the <requested dump> value from the previous +CCED command will be used. If no previous +CCED <requested dump> value is available, a default value of 13 (8, 4, and 1) will be used.

For <requested dump> 4, 2, and 1, the requested information is output using the unsolicited +CCED response. Place holders are used in the +CCED output for fields that cannot be measured or are not meaningful in the current mode of operation. In this case, consecutive commas will be present in the output. There are also several optional parameters ([]) that are not displayed in AMPS mode and will result in place holders in the +CCED command output. Automatic snapshots of these dumps are not supported during communication or registration.

For <requested dump> 8, the information is output using the unsolicited +CSQ response. The 07.07 format of the +CSQ response is respected. However, the <fer> portion of the +CSQ response is not evaluated by this dump request so the <fer> value will always be 99. Automatic snapshots are supported in idle mode and during communication.

The combination of multiple <requested dump> values (addition of the values) in a single +CCED command is supported with the exception of <requested dump> 2. The <requested dump> 2 value must be use by itself and not in combination with other dump request values.

Either or both the +CCED and +CSQ responses are used for output depending upon the <requested dump> value. Activation or deactivation of a +CCED response flow will not affect an existing +CSQ response flow. Likewise, activation or deactivation of a +CSQ response flow will not affect an existing +CCED response flow.
