codes (bit oriented messages, BOM) on all eight channels independent from each other:
•
•
•
Loop switching (“Out-band loop switching”) is possible by enabling of the BOM receiver
1 signaling (MODE.BRAC = ´1´ and CCR1.EITS = ´1´) and detection of the following Out-
Band loop messages related to ANSI-T1.403, 1999, table4:

If the register bit CCR2.RBFE is set, BOM messages are accepted if at least seven
consecutive and identical BOM messages were received.
Dependent on the BOM mode (configured by register bits CCR1.BRM and CCR2.RBFE)
the content of register RSIS will be written as last byte into the receive FIFO.
Automatic loop switching by BOM messages is logically ored with the appropriate loop
switching by register bits.

Detection of Out-band loop codes (BOM).
Generation of Out-band loop codes (BOM) by setting of the appropriate DL-bits by
the micro controller.
Automatic loop switching (activation and deactivation, for remote loop and payload
loop) based on detected Out-band loop codes.
