This chapter details the modifications to the Digital Tone Generator (DTG or DTG-2), Call Progress Analyzer (CPA) cards, and Service Platform Card (SPC)-CPA service circuits to support the following features:
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 Guangdong network.
| Tone | Frequencies (Hz) | Amplitude (dBm) | Cadence | Detected by CPA? |
|---|---|---|---|---|
Dial | 450 | -10 | Continuous | Yes |
Ringing | 450 | -10 | 1 second on, | Yes |
Busy | 450 | -10 | 0.35 seconds on, | Yes |
Number Unavailable | 400 | -9 | 75 milliseconds on, | Yes |
Table 3-2 lists two additional DTG tones for VCO/4K conferences. These tones inform conference participants when another conference party or recording device is attached to the conference.
| Tone | Frequency (Hz) | Amplitude (dBm) | Cadence | Detected by CPA? |
|---|---|---|---|---|
Intrusion | 1400 | -12 | 150 ms on, | No |
Recorder Warn | 1400 | -12 | 500 ms on, | No |
CPA and SPC-CPA processing is modified to support the Guangdong province network requirements. Use the system administration answer supervision templates function to control tone detection for dial tone, busy tone, ringing tone, and number unavailable tone. 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 3-3 shows the Answer Supervision Template screen terms to use with the China country feature package.
Because the conference tones are used only in conference structures and are not transmitted or received over the network, no detection functions are required.

Table 3-4 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 3-4.
