• Manufacturer Part Number: pef80913
• Description: 2b1q Second Gen. Modular Isdn Nt
• Manufacturer: Infineon Technologies Corporation

Test Modes
The test patterns on the S-interface (‘2 kHz Single Pulses‘, ‘96 kHz Continuous Pulses‘)
and on the U-interface (‘Data Through‘, ‘Send Single Pulses‘) are invoked via C/I codes
(TM1, TM2, DT, SSP). Setting SRES.RES_U to ‘1‘ forces the U-transceiver into test
mode ‘Quiet Mode‘ (QM), i.e. the U-transceiver is hardware reset.

The U-transceiver, S-transceiver and the IOM -2 channels can be controlled and
monitored via:
Data Sheet
a) the parallel or serial microprocessor interface
- Access of on-chip registers via µP interface Address/Data format
- Activation/Deactivation control of U- and S-transceiver via µP interface and C/I
handler
- Q-SMINT I is Monitor channel master
- TIC bus is transparent on IOM -2-interface and is used for D-channel arbitration
between S-transceiver and off-chip HDLC controllers.
