This chapter details the modifications to the Digital Tone Generator (DTG or DTG-2) and Call Progress Analyzer (CPA), and SPC-CPA service circuits to support the supervision tones specific to the South Africa telephone network.
The information in this chapter supersedes the information in the following manuals:
Table 2-1 summarizes the characteristics of the most frequently used supervision tones in the South Africa network.
| Tone | Frequencies (Hz) | Amplitude (dBm) | Cadence | Detected by CPA? |
|---|---|---|---|---|
Dial | 400 modulated 33 at 90% | -8 | Continuous | Yes |
Ring | 400 modulated 33 at 90% | -8 | 0.4 seconds on, | Yes |
Busy | 400 | -8 | 0.5 seconds on, | Yes |
Reorder | 400 | -8 | 0.25 seconds on, | Yes |
SIT | 950 | -8 | 0.33 seconds on, | Yes |
Intrusion | 400 | -8 | 0.15 seconds on, | No |
Call Notify | 900 | -8 | 0.2 seconds on, | No |
Comfort | 950 | -8 | 0.66 seconds on, | Yes—as Pager |
Call Waiting | 400 modulated 33 at 90% | -8 | 0.25 seconds on, | Yes—as Reorder |
Number Unavailable | 400 | -8 | 2.5 seconds on, | Yes—as SIT |
Positive Acknowledge | 700 | -8 | 0.25 seconds on, | Yes—as Reorder |
CPA processing is modified to support the South Africa 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 South Africa country feature package.

Tone generation is performed through DTG outpulse and static tone channels. The allocation of these tones is controlled via inpulse rules, the Voice Path Control ($66) command and the DTMF Collection Control ($67) command.
Table 2-3 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 2-3.
