This chapter details the modifications to the Digital Tone Generator (DTG or DTG-2) and Call Progress Analyzer (CPA) card, and Service Platform (SPC)-CPA service circuits to support the supervision tones specific to the Thailand telephone network.
The information in this chapter supersedes the information in the following manuals:
Table 3-1 summarizes the characteristics of the most frequently used supervision tones in the Thailand network.
| Tone | Frequencies (Hz) | Amplitude (dBm) | Cadence | Detected by CPA? |
|---|---|---|---|---|
Dial | 400 | -10 | Continuous | Yes |
Ring | 400 | -10 | 1 second on, | Yes |
Busy | 400 | -10 | 500 milliseconds on, 500 milliseconds off, REPEATED | Yes |
Reorder | 400 | -10 | 300 milliseconds on, 300 milliseconds off, REPEATED | Yes |
Number Unavailable | 400 | -9 | 100 milliseconds on, 100 milliseconds off, 100 milliseconds on, 100 milliseconds off, 100 milliseconds on, 100 milliseconds off, 300 milliseconds on, 100 milliseconds off, REPEATED | Yes—as SIT |
SIT | 950 | -13 | 330 milliseconds on, 330 milliseconds off, 330 milliseconds on, 990 milliseconds off, REPEATED | Yes |
CPA and SPC-CPA processing is modified to support the Thailand network requirements. Use the system administration answer supervision templates function to control tone detection for the tones listed in Table 3-1. Supervision template processing is described in the Cisco VCO/4K System Administrator's Guide.
The supervision events and tones listed in the Answer Supervision Template screen use standard North American network terminology. Table 3-2 shows the Answer Supervision Template screen terms to use with the Thailand country feature package.

Table 3-3 supersedes the tone generation table listed in the Cisco VCO/4K Programming Reference and the Cisco VCO/4K Extended Programming Reference. It also supersedes the tone output level specifications found in the Cisco VCO/4K Card Technical Descriptions. For more information on generating tones, refer to the Cisco VCO/4K System Administrator's Guide.
The tones and their corresponding output levels, decimal values, hexadecimal values, and port addresses are summarized in Table 3-3.
