Telephone Signalling Transceiver / Least Cost Router
CMX860
1.5.10 Rx Modem Pattern Detectors
The '1010' pattern detector will set bit 9 of the Status Register when 32 bits of alternating 1's and 0's have
been received. The continuous 1's detector will set bit 7 of the Status Register when 32 consecutive 1's
have been received. Both pattern detectors will hold their 'detect' output for 12 bit times after the end of
the detected pattern unless the received bit rate or operating mode is changed, in which case the
detectors are reset within 2ms.
1.5.11 Analogue Signal Routing
The routing of signals to and from the Line and Phone interfaces is performed by bits 0 to 4 of the
Analogue Signal Path Register. Please note that bits 5 to 7 of this register are reserved for future use
and should be set to zero.
