TC35i_ATC_V01.05 Page 211 of 278 04.08.2003
<Timeslot> (numeric) Assigned timeslot. If mobile is in idle mode, timeslot 0
(BCCH timeslot) will be indicated.
0 ... 8 assigned timeslot 0 (BCCH timeslot) in IDLE mode
<TA> (numeric)
Timing Advance for the serving cell, in bits.
<RSSI> (numeric)
Receive Level, with value 99 indicating ”not known or not detectable”
0 ... 31 signifying the RSSI range from -113dBm or less (”0”)
to -51dBm or greater (”31”) in steps of -2dBm
(e.g. ”1” = -111 dBm, ”2” = -109 dBm ..., ”30” = -53dBm)
<BER> (numeric)
Bit Error rate, with value 99 indicating ”not known or not detectable”
0 ... 7 as RXQUAL values RXQUAL0 to RXQUAL7 in GSM 05.08
section 8.2.4

Notes
· To some extent, the cell monitoring commands AT^SMOND , AT^MONI ,
AT^MONP and AT^SMONC cover the same parameters. The receiving
level, for example, can be queried with all three commands. Yet the resulting
values may be slightly di_erent, even though obtained over a time period of
a few seconds. This is quite normal and nothing to worry about, as the cell
information is permanently updated.
· During a connection, not all of the neighbour cell information can be de-
coded. The following restrictions apply:
- Information is updated only for neighbour cells that have already been
visible at connection setup, and continue to be included in the list of cells.
- New neighbour cells added to the list, for example after handover, cannot
be displayed until the connection is released.
· Parameters not available or invalid are left out. In this case, two consecutive
commas are presented. For example, if <format> equals 1, the resulting re-
sponse with parameter <cell> unavailable would read:
^SMOND: <MCC>, <MNC>, <LAC>, <BSIC>, <chann>, <RxLev>,
<RxLev>Full, <RxLev>Sub, <RxQual>, <RxQual>Full, <RxQual>Sub,
<Timeslot><CR><LF>
· Parameter sets not requested with input parameter <format> will be left out
altogether. For example, the response for <format> = 12 will read:
^SMOND: <TA>, <RSSI>, <BER><CR><LF>
