Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide (PN S000478C)
This command can be used by the application to retrieve information about the main cell and up
to six neighboring cells. This is an extended command that may be used in two different
The +CCED command supports two modes of operation: on request by the application or
automatically by the product every 5 seconds. Signal strength can also be reported when the
change exceeds a threshold.
Command syntax: AT+CCED=<mode>[, <requested dump>[,<sqStep>]]
<mode>
<requested dump> This parameter is specified as the summation of one or more of the
<CsqStep>

Note: <requested dump> is the most
recently requested one. If none
requested, <requested dump>=1 will be
displayed.

Note: One time dump of the <requested
dump> that was last requested. If none
requested, <requested dump>=1 will be
displayed

Main Cell Indication
Main Cell RSSI Indication (RxLev) from 0 to 31 and frame error rate. Set
the AT+CSQ command description for more information.
Unsolicited +CSQ reports due to changing RSSI levels are disabled.
Whenever the RSSI changes by this amount or more, an unsolicited +CSQ
report is generated.
