Guandong Tone Plan

This chapter details the modifications to the Digital Tone Generator (DTG or DTG-2), Call Progress Analyzer (CPA) cards, and Service Platform Card (SPC)-CPA service circuits to support the following features:

Supervision tones specific to the Guangdong telephone network
Additional tones used with the conferencing capabilities of the VCO/4K

The information in this chapter supersedes the information in the following manuals:

Cisco VCO/4K System Administrator's Guide
Cisco VCO/4K Standard Programming Reference
Cisco VCO/4K Extended Programming Reference

Tone Characteristics

Table 3-1 summarizes the characteristics of the most frequently used supervision tones in the Guangdong network.

Table 3-1: Guangdong Digital Tone Generator Supervision Tones

Tone	Frequencies (Hz)	Amplitude (dBm)	Cadence	Detected by CPA?
Dial	450	-10	Continuous	Yes
Ringing	450	-10	1 second on, 4 seconds off, REPEATED	Yes
Busy	450	-10	0.35 seconds on, 0.35 seconds off, REPEATED	Yes
Number Unavailable	400	-9	75 milliseconds on, 100 milliseconds off, 75 milliseconds on, 100 milliseconds off, 75 milliseconds on, 100 milliseconds off, 75 milliseconds on, 400 milliseconds off, REPEATED	Yes

Table 3-2 lists two additional DTG tones for VCO/4K conferences. These tones inform conference participants when another conference party or recording device is attached to the conference.

Table 3-2: Guangdong Digital Tone Generator Conference Tones

Tone	Frequency (Hz)	Amplitude (dBm)	Cadence	Detected by CPA?
Intrusion	1400	-12	150 ms on, 1.5 seconds off, REPEATED	No
Recorder Warn	1400	-12	500 ms on, 1.5 seconds off, REPEATED	No

CPA and SPC-CPA processing is modified to support the Guangdong province network requirements. Use the system administration answer supervision templates function to control tone detection for dial tone, busy tone, ringing tone, and number unavailable tone. Supervision template processing is described in the Cisco VCO/4K System Administrator's Guide.

Answer Supervision Template Screen Terminology

The supervision events and tones listed in the Answer Supervision Template screen use standard North American network terminology. Table 3-3 shows the Answer Supervision Template screen terms to use with the China 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.

Tone Generation

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), and DTMF Collection Control ($67) commands.

Table 3-4 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 3-4.
