1.4

Not Supported are ...

• Integrated U-hybrid

• ’Self test request’ and ’Self test passed’ of U-transceiver

• TE-mode of the S-transceiver

• DECT-link capability

• SRA (capacitive receiver coupling is not suited for S-feeding).

• ’NT-Star’ with star point on the IOM®-2 bus (already not supported in INTC-Q).

• HDLC Automode

• No access to S2-5 channels. Access only to S1 and Q channel as in SCOUT. No

selection between transparent and non-auto mode provided.

• The oscillator architecture was changed with respect to the INTC-Q to reduce power

consumption. As a consequence, the Q-SMINT®IX always needs a crystal and pin

XIN can not be connected to an external clock as it was possible for IEC-Q and NTC-

Q. This does not limit the use of the Q-SMINT®IX in NTs since all NT designs use

crystals anyway.

1.5

Different are ...

• HDLC naming convention of transparent modes has changed (as in SCOUT). The

according bit combination in the MODEH register remains unchanged, hence

software compatibility is ensured.
