1 Introduction
DIGITAL RADIO TESTER CTS 60 1094.0006
6.5 Autotest Menus
6.6.2 Synchronisation Menu (GAP Mode Portable Part Tests)
This menu appears when the Manual Test is activated for testing a portable part and GAP Mode is "ON".
On the top right-hand side of the screen is the configured PARK (Private Access Rights Key). This is the PARK that the CTS60 will transmit. In order for the portable part to synchronise to the CTS60, it needs to be subscribed to a fixed part with this PARK.
Note: The CTS can, if required, be used to accomplish the subscription of the portable part and this will
be described later in the chapter.
On the lower centre right-hand side of the screen is the configured IPUI (International Portable User Identifier) of the portable part to be tested.
On the bottom right-hand side of the screen is the selected portable part. This will define various configured settings specific to the portable part being tested.
On the top left side of the menu important Manual Test settings are indicated, these are: • the slot and carrier of the dummy bearer we are currently transmitting.
• the carrier offset being used to modify all dummy and traffic carrier numbers. • the CTS60 transmit level in dBm.
Connect
By pressing this key the CTS60 will make a call to the portable part. If you take the portable part off hook the CTS60 will attempt to set up a connection.
Note: 1. You can setup a connection only by taking the portable part off hook.
2. Different to non GAP Mode: the portable part doesn’t need to be in test mode.
Edit PARK (Private Access Rights Key)
By pressing this key the configured PARK value can be edited.
Subscribe
Pressing this softkey displays a further menu where subscription of the portable part can be initiated if required.
RF Con/PP Type
Pressing this key allows the combination of connectors, the coupler state, and the type of Portable Part being tested to be selected.
Config
Pressing this key allows the values used by the synchronisation menu to be configured.
Menu up
6.6.2.1 Subscription of the Portable Part
After pressing the “Subscribe” softkey as described in section 6.6.2, the following menu will be displayed.
The following softkeys are present.
Start Subscr
Press this softkey to start the subscription process. The DUT, in this case the portable part, must already be in subscribing mode and ready to be subscribed.
Edit IPUI (International Portable User Identifier)
By pressing this key the configured IPUI value can be edited. Editing this field is typically only required if the IPUI of the portable part DUT is known and is already subscribed to the fixed part which is to be simulated by the CTS. If subscription is to be attempted, then the field should be left unmodified but will be automatically updated at a later stage, in the event that the subscription process completes successfully.
Edit AC
By pressing this key, the configured Access Code can be edited. This Access Code corresponds directly to a user PIN, which is required for entry during the subscription process of the portable part DUT. This PIN, will typically only four digits in length. The Access Code field however has provision for a PIN length of eight digits. In the event that the PIN is only four digits, then the remaining four characters of the Access Code field must be left at their default value of FFFF.
The portable part DUT may not accept all combinations of PIN and this point should be clarified in the appropriate documentation, if there is any doubt.
Return
This will return to the Synchronisation Menu (GAP Mode Portable Part Tests) menu described in section 6.6.2 where a connection with the portable part can be attempted if required.

6.6.2.2 Subscribing the Portable Part
After the subscription process has been initiated, then the following menu will be displayed. It is at this point where the portable part DUT must already have been configured to accept subscription and must be waiting for this event to occur.
If this procedure is not followed exactly, then the results will be unpredictable and the subscription process is unlikely to succeed.
If subscription is successful, then the menu will automatically change to the menu described in the previous section 6.6.2.1 and the portable part will indicate that the process has completed as documented. The IPUI field in that same menu will be updated with the identity of the newly subscribed portable part DUT.
Subscription can fail for a number of reasons of which some of the more likely explanations are now listed.
•
The RF output level of the CTS may be set too low to be interpreted correctly by the portable part DUT.•
The user defined PARK may not be acceptable for use by the portable part DUT. Consult the relevant documentation to ascertain the validity of the PARK being used with the portable part DUT.•
The PIN entered on the portable part DUT may not match the configurable Access Code describedin the previous menu.
