This chapter details the modifications to the Digital Tone Generator (DTG or DTG-2) and Call Progress Analyzer (CPA), and Service Platform (SPC) cards to support the supervision tones specific to the Singapore 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 and conference tones in the Singapore network.
| Tone | Frequencies (Hz) | Amplitude (dBm) | Cadence | Detected by CPA? |
|---|---|---|---|---|
Dial | 425 | -15 | Continuous | Yes |
Ringing | 425 (modified by 25) | -10 | 0.4 seconds on, | Yes |
Busy | 425 | -10 | 750 milliseconds on, | Yes |
Reorder | 425 | -10 | 250 milliseconds on, | Yes |
PIP | 900 | -10 | Continuous | No |
Fax | 2100 | — | Continuous | Yes1 |
SIT | 950 | -12 | 0.33 seconds on, | Yes |
| 1The fax tone is not generated, but is detected as ISUP cessation. |
CPA processing is modified to support the Singapore 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 Singapore country feature package.

Table 3-3 supersedes the tone generation 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 3-3.
