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 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 China network.
.
| Tone | Frequencies (Hz) | Amplitude (dBm) | Cadence | Detected by CPA? |
|---|---|---|---|---|
Dial | 450 | -10 | Continuous | Yes |
Ringback | 450 | -10 | 1 second on, | Yes |
Busy | 450 | -10 | 0.35 seconds on, | Yes |
Fast Busy | 450 | -10 | 0.7 seconds on, | Yes |
Number Unavailable | 450 | -10 | 0.1 seconds on, | No |
Toll | 450 | -20 | 0.2 seconds on, | No |
Queue Wait | 450 | N/A | 1 second on, | Yes—as Ringback |
Call Wait | 450 | -20 | 0.4 seconds on, | No |
Conference (Reminding) | 450 | -20 | 0.4 seconds on, | No |
Call Back | 950 | -20 | Continuous | Yes—as Dial |
ISUP Tone 1 | 2010 | -12 | Continuous | Yes |
ISUP Tone 2 | 1800 | -22 | Continuous | Yes |
 |
Note The China 3 Tone Plan was taken from a specification. The Howler tone, which has varying amplitude, was not implemented. The Number Unavailable tone with 100 ms tone pulses, cannot be detected by CPA. The ISUP tones at 1800 Hz and 2010 Hz are located in the same time slots as the North American tone plan. |
CPA processing is modified to support the China 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 China 3 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.

The tone generation information affects 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.
