This chapter details the modifications to the Digital Tone Generator (DTG or DTG-2), Call Progress Analyzer (CPA), and Service Platform (SPC) cards to support the supervision tones specific to the Hong Kong telephone network.
The information in this section supersedes the information in the following manuals:
Table 2-1 summarizes the characteristics of the most frequently used supervision tones in the Hong Kong network.
| Tone | Frequencies (Hz) | Amplitude (dBm) | Cadence | Detected by CPA or SPC |
|---|---|---|---|---|
Dial | 350 + 440 | -13 | Continuous | Yes |
Audible Ringback | 440 + 480 | -13 | 0.4 seconds on, | Yes |
Busy | 480 + 620 | -13 | 0.5 seconds on, | Yes |
Fast Busy | 480 + 620 | -13 | 0.25 seconds on, | Yes |
Number Unobtainable | 480 + 620 | -13 | Continuous | Yes1 |
| 1The Number Unobtainable tone is detected as the special information tone. |
CPA processing is modified to support the Hong Kong network requirements. Use the system administration answer supervision templates function to control tone detection for the tones listed in Table 2-1. 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 2-2 shows the Answer Supervision Template screen terms to use with the Hong Kong country feature package.

Table 2-3 supersedes the tone generator table listed in the Cisco VCO/4K Standard 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 2-3.
