Table 7: Programming the tone generators
The sine wave is filtered by a bandpass, the Q factor of this band filter can be altered in
the range from 0 to 7 and can be programmed by setting the first nibble of byte 3 to the
corresponding value (always 5 in this table). The resulting signal amplitude can be set
by programming the filters AR1 and AR2.
10.3
The caller ID interface is compatible with Bellcore TR-NWT-000030 and SR-TSV-
002476 as regards generic requirements for transmitting asynchronous voice-band data
to customer premises equipment (CPE) from a serving stored-control switching system
(SPCS) or a central office (CO). In this service, the information about the calling party is
embedded in the silent interval between the first and the second ring. During this period,
ALIS receives and stores up to 4096 bits of the1200-baud FSK signal. The decoding also
complies with BELL 202 and CCITT V.23 specifications. (see “Programming the ALIS
Caller ID Coefficients” on page 81)
