Example code showing a dual-band handover from E-GSM to DCS
Example code showing a dual-band handover
from E-GSM to DCS
Some example code is listed below which performs a dual-band handover
from E-GSM to DCS on an HP/Agilent 8922 GSM HSCSD Test System.
The technique is to use the standard dual-band command sequence, but
send this to both HP/Agilent 8922 units. Note that after ending a call,
the slave unit remains in the DCS band, therefore it is good practice to
set the radio band prior to starting the HSCSD call.
