Downlink MCS-5
Press this softkey to select a downlink packet data traffic channel with
block type 9 that is in compliance with GSM 05.03. The MCS5 radio
block contains a single RLC data block of 448 bits with a code rate of
0.37. This ensures that the maximum amount of Forward Error
Correction (FEC) has been applied to the data.

Downlink MCS-9
Press this softkey to select a downlink packet data traffic channel with
block type 13 that is in compliance with GSM 05.03. The MCS9 radio
block contains two RLC data blocks of 592 bits with a code rate of 1.0.
No Forward Error Correction (FEC) has been applied to the data, thus
reducing the overhead and enabling the fastest data rate transmission.

Down TCH
Press this softkey to select downlink traffic channel (base station to
mobile) as the timeslot type for the active timeslot. Downlink timeslots
cannot be mixed with uplink timeslots.
You cannot mix downlink and uplink timeslots. When a timeslot is
designated as uplink, it changes to downlink if any other timeslot is
designated as downlink.
When you select
Down TCH
, the frame pattern is output with
continuous RF power. Power is on during off timeslots (according to the
standard) and a continuous pattern of binary ones is sent during off
timeslots.
When you select
Down TCH
for a timeslot, the visual representation of
the timeslot pattern updates.
