This chapter details the modifications to the Digital Tone Generator (DTG) and Call Progress Analyzer (CPA) to support the following features:
The information in this chapter supercedes the information in the following manuals.
The characteristics of the four most common supervision tones used in the German network are summarized in Table 3-1.
| Tone | Frequencies (Hz) | Cadence | Generate | Detect | Port Address |
|---|---|---|---|---|---|
Dial | 425 | Continuous | X | X | 04C2 |
Ringing | 425 | 1.0 seconds on, | X | X | 04D0 |
Busy | 425 | 0.48 seconds on, | X | X | 04D1 |
Reorder | 425 | 0.24 seconds on, | X | X | 04D2 |
CPA processing is modified to support German network requirements. Use the system administration answer supervision templates function to control tone detection for dial, ringing, busy, and reorder. Supervision template processing is described in the Cisco VCO/4K System Administrator's Guide.
The supervision events listed on the Answer Supervision Template screen are based on standard North American network terminology. Table 3-2 shows the North American terms and the German terms.
| North American Term | German Term |
|---|---|
Ringback | Ringing Tone |
Reorder | Disconnect Tone |
Because the conference tones are used only within conference structures and are not transmitted or received over the network, no detection functions are required.
Tone generation is performed using DTG outpulse and static tone channels. The allocation of these tones is controlled via inpulse rules, Voice Path Control ($66) commands, and DTMF Collection Control ($67) commands. The tones and their corresponding decimal values, hexadecimal values, and port addresses are summarized in Table 3-3.
This 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.
