Packet Data –
Traffic Channel
The
Packet Data – Traffic Channel
section defines the power control parameter P0
and the traffic channel that the CMU will use for data transfer:
P0
Downlink power control parameter P0; see background
information at the beginning of this section
RF Channel
GSM channel that the CMU will use for packet data transfer
Hopping Sequence
Hopping sequence containing up to 6 channel numbers.
Off
is
used to shorten the hopping sequence. Frequency hopping of
the downlink traffic channel must be enabled explicitly.
Hopping
Enable
(On)
or disable frequency hopping in the downlink
traffic channel.
Reference Level
Reference value for the downlink (BS) signal levels. The
reference level is calculated from the BCCH level of the BS
signal and the downlink power control parameter P0
according to
Reference Level = –85 dBm – P0.

The remaining settings are described in section
RF Signals of the MS (Connection Control – MS
Signal)
on p. 4.195 ff. The relationship between the table-oriented
BS Signal
tab and its softkey-
oriented counterpart is analogous the
MS Signal
tab.
Network Parameters (Connection Control – Network)
The
Network
tab defines various parameters of the network that the CMU reports to the mobile station.
The following settings are (E)GPRS-specific and available with option CMU-K42/-K43,
