Signalling States
The
Signalling States
section indicates the current signalling states of the CMU in
GSM
(Circuit Switched,
see
Fig. 4-41
on p. 4.90
)
and GPRS
(Packet Data)
mode.
GSM and GPRS states are independent from each other. The GPRS signalling
scheme is described in section
GPRS Signalling
on p. 4.187 ff.
The signalling states of the CMU are changed by means of the right softkeys in the
Connection
tabs of the
Connection Control
menu; see below.

MS Capabilities
The
MS Capabilities
section indicates the characteristics of the mobile station
under test. Valid parameter values are available as soon as the CMU has reached
the GSM
Synchronized
or in the GPRS
Attached
signalling states. The
Dialed
Number
is shown after a
Call from MS

MS Revision Lev.
GSM phase (Phase 1, Phase 2 or Phase 2+) of the mobile
station
Supp. Bands/PC
Supported GSM band(s), power class and nominal maximum
output power in dBm of the mobile station. For GSM900 mobile
stations, the R-GSM, E-GSM, and P-GSM subbands are also
indicated, e.g.
E-GSM / 1 (max. 39 dBm).
For mobiles supporting
several GSM bands or subbands, several lines are indicated.
Multislot Class
Multislot class of mobile station in GSM
(Circuit Switched)
and
(E)GPRS
(Packet Data)
mode and in the format
<Multislot
Class> (<max. no. of downlink slots> Dn/<max. no. of uplink
slots> Up/<Sum> Sum)
, e.g. 4 (2 Dn/2 Up/3 Sum). A mobile
station may indicate different multislot classes for circuit mode
services and for GPRS (see GSM 04.08). The MS multislot
classes are defined in 3GPP TS 05.02 and listed in
Table 4-10
below
.
