This chapter details the modifications to the Digital Tone Generator (DTG or DTG-2), Call Progress Analyzer (CPA) card, and SPC-CPA service circuits to support the supervision tones specific to the Mexico network.
The information in this supplement supersedes the information in the following manuals:
Table 3-1 summarizes the characteristics of the most frequently used supervision tones in the Mexico network.
| Tone | Frequency (Hz) | Amplitude (dBm) | Cadence | Detected by CPA? |
|---|---|---|---|---|
Dial | 425 | -10 | Continuous | Yes |
Ring | 425 | -10 | 1 second on, | Yes |
Busy1 | 425 | -10 | 0.25 seconds on, | Yes—detected as Reorder |
Reorder1 | 425 | -10 | 0.25 seconds on, | Yes |
Special | 950 1400 1800 | -10 | 0.33 seconds on, | Yes |
Intervention | 425 | -10 | 500 milliseconds on, | Yes—detected as Busy |
Waiting | 425 | -10 | 200 milliseconds on, | No |
| 1The busy tone and the reorder tone share the same time slot, 4D2. Refer to Table 3-3 for further information. |
CPA processing is modified to support the Mexico network requirements. Use the system administration answer supervision templates function to control tone detection for tones listed in Table 3-1. Supervision template processing is described in the Cisco VCO/4K System Administrator's Guide.
 |
Note The supervision events listed in the Answer Supervision Template screen are based on standard North American network terminology. The terms "ringback" and "audible ringback" are synonymous with the term "ringing tone." The terms "reorder" and "fast busy" are synonymous with the term "disconnect tone." |
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 Mexico country feature package.

Tone generation is performed through DTG outpulse and static tone channels. The allocation of these tones is controlled via inpulse rules, Voice Path Control ($66) commands, and MF Collection Control ($68) commands.
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 shown in Table 3-3.
