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 Taiwan 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 Taiwan network.
| Tone | Frequencies (Hz) | Amplitude (dBm) | Cadence | Detected by CPA? |
|---|---|---|---|---|
Dial | 350 + 440 | -16 | Continuous | Yes |
Ringback | 440 + 480 | -22 | 1 second on, | Yes |
Busy | 440 + 480 | -27 | 0.5 seconds on, | Yes |
Fast Busy | 440 + 480 | -27 | 0.25 seconds on, | Yes |
Call Wait A | 440 + 480 | -22 | 0.25 seconds on, 0.25 seconds off, 0.25 seconds on, 3.25 seconds off, REPEATED | No |
Call Wait B | 350 + 440 | -16 | 0.25 seconds on, 0.25 seconds off, 0.25 seconds on, 3.25 seconds off, REPEATED | No |
CPA processing is modified to support the Taiwan 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 Taiwan country feature package.

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.

| 1Taiwan network needs to use the MF digit STP at port address 04FD as its ST frequency code in order to obtain the tone frequency desired. |
The Taiwan network's DTMF and MF outpulsing varies from standard outpulse timing and cadence.
DTMF pulses are transmitted at 10 digits per second, with the tone's cadence set to 50 milliseconds on, 50 milliseconds off. In addition, MF(R1) pulses are transmitted at 10 digits per second, with the tone's cadence set to 67 milliseconds on, 33 milliseconds off.
