Chapter 5: SYSTEM SETTINGS BY SOFTWARE
(8) WAN port No.
Set the start port number to be used for each protocol as viewed from the WAN side.
[Web server]
Allows entry of the Web server's port number. The valid range is from 1 to 65535. The default factory
setting is 80.
[TCP port]
Allows entry of TCP port start number other than the Web server. The valid range is from 1 to 65532. The
AN-8000 system uses 4 consecutive ports starting with the TCP start port. The default factory setting is
5000.
[UDP port]
Allows entry of UDP port start number to be used. (valid range from 1 to 65516) The AN-8000 system
uses 20 consecutive ports starting with the UDP start port. The default factory setting is 5006.
(9) Available bit rate
Set the capacity (or a usable upper limit value) of the network line to which the Exchange is connected.
Setting this communication capacity prevents sound quality deterioration and longer time delays caused
by excess conversation and/or paging communications traffic.
(10) Broadcast Spec
Select the voice transmission mode that is appropriate for the usable frequency band.
• High Quality Sound Transmission Mode
Transmits voices at high sound quality with short time delay. Use this mode as the normal default
mode.
• Standard Mode
Transmits voice audio with a short time delay. In this mode, the sound quality is reduced, but the delay
time is identical to that in high quality mode, allowing a narrower frequency band to be used. Use this
mode when exchanges are connected via an ISDN line (128 kbps).
• Band Width Saving Transmission Mode
Voice transmission uses a very narrow frequency band, but with lesser quality sound and longer time
delay. Use this mode when exchanges are connected via an Analog line (56 kbps).
