Planet IPX-1000 Инструкция по эксплуатации онлайн [48/79] 65971

PBX/PSTN will give IPX-1000 a busy tone automatically. If the other VoIP device of IP side answers

and hangs up the phone, the IPX-1000 will release the line port automatically without analyzing busy

tone from PBX/PSTN.

PBX system advance

There are three parameters received from PBX/PSTN.

Busy tone frequency 1

Busy tone frequency 2

Busy tone sensitive: High, Median, Low level

Because the different rule and frequency from other countries, parameters have to be properly

configured to recognize busy tone correctly.

How to configure busytone on IPX-1000

IPX-1000 has a default setting of busytone (busytone frequency 1; busytone frequency 2 and busytone

sensitive), which is based on busytone of the Taiwan Telecom PSTN network. If the busytone was

recognized correctly, the DSP IC in IPX-1000 will release the line port connected to PBX/PSTN

immediately when detecting of busytone. Otherwise it may be released after one minute or lock this line

permanently. The tone table parameters are shown as following example:

Busytone frequency 1:

480/620: Low frequency is 480 HZ, High frequency is 620 HZ

Busytone frequency 2:

400/450: Low frequency is 400 HZ, High frequency is 450 HZ

Most busy tone of PSTN or PBX is composed by two different frequencies, in Taiwan, for example,

480Hz+620Hz. In such case, you have to assign the two frequency values. But in some area, the busy

tone frequency may be composed by only one frequency; in this case, you have to assign the two fields

with same value. For example, if your PSTN busy tone is single frequency, let’s say 450Hz. Then you

have to fill the two fields with 450/450. The IPX-1000 will recognize them as single frequency.

The IPX-1000 allows you to enter two groups of busy tone setting. Because in many cases.

The gateway has to detect two sources of busy tone. One from PSTN side and the other from PBX side.

So it is necessary to have two groups of setting.

If the IPX-1000 can’t hang up the phone, maybe it is because the PBX/PSTN

Frequency is not the value as default shown as above; you need to adjust Tone Table parameters

manually
