(ECC) – Connector cables to external devices
Three cables are connecting external devices to the baseband module:
• SPARC connector
• Option connector
• Handset connector
If any external connector verification flow is failing, each of these three connector cables are examined for errors.
If no errors are found on the cables, the baseband module PCB probably need to be replaced. If a power supply
measure fails in any of the external connector checks, proceed to verification of the power supply module
(SMPS).
(TIC) – Transceiver interconnection
The internal transceiver connection between the baseband board and the RF board contains:
• Radio control signals.
• Voice receiver/transmitter AF signals and the DSC receiver AF signal.
In the following it is possible to identify if there is a problem on either two boards connected with the cable.
