F-SCH

Supplemen-
tal Channel
Traffic Channel contains user
data only, operates in conjunc-
tion with a Forward Fundamental
Channel or a Forward Dedicated
Control Channel to provide
higher data rate services.
F-SCH can only be used with
RC3 to RC12. The channel uses
variable length Walsh Codes to
provide a constant spreading
rate. It provides data rates from
1.2 kbit/s up to 1036.8 kbit/s.

Fundamen-
tal Channel
The F-FCH contains control data
and user data.
It is a sub channel of the traffic
channel. The traffic channel is
used for transmitting the radio
link information, i.e. for communi-
cation addressee.
