low users to perform call processing tests through GSM
base station simulators. This allows service technicians
to perform simulations without accessing the customer’s
cellular account.
Hardware Requirements
There are various hardware configurations to perform
manual call processing procedures. Below, is a list of
the various options. All options require the battery to
be attached. A GP-gate system can also be used for
manual testing. Refer to the GP-gate user’s manual for
details.
Power Options
• Fully Charged Battery (SNN5639B¹ or equiva-
lent)
• Full-Rate Power Supply (PSM5049A¹)
• Battery Eliminator (5-00-3F-10000²) with 2-
Wire Adapter (2-00-68-10000²)
