Value Requested Dump
If requested dump parameter is not provided, one of the last +CCED commands sill be used (or 15 by default) will
be used.
Values of MCC/MNC are set to 0 in the case of “No service”.

Command syntax: AT+CCED=<mode>[, <requested dump>]
Command
AT+CCED=0
Note: Last request was AT_CCED=0,3 (main cell
and neighbors 1 to 6): you can see MCC,MNC
sequences (here 208,20)
AT+CCED=0,1
Note: Only Main Cell request
AT+CCED=0,1
Note: Call in progress: RxLev and RxQual are
empty, RxLevFull, RxLevSub, RxQualFull, and
RxQualSub have data

+CCED response: Main Cell only
+CCED response: Neighbors 1 to 6
+CCED response: Main Cell; then Neighbors 1
to 6
+CCED response: Timing Advance Only
+CCED response: Main Cell; then Timing
Advance
+CCED response: Neighbors 1 to 6; then
Timing Advance
+CCED response: Main Cell; then Neighbors 1
to 2, then Timing Advance
+CSQ response: Main Cell RSSI indications
