Configuration Mode: Editing Configuration Settings

2.12.15 Default Settings

The following applies to new systems and those defaulted using the Erase Configuration command. They also apply to

IP500 and IP500 V2 control units defaulted using the reset button on the rear of the unit (refer to the Installation manual

for details of using the reset button).

For B5800 Branch Gateway only the Avaya Branch Gateway SD card should be used.

· A-Law or U-Law

PCM (Pulse Code Modulation) is a method for encoding voice as data. In telephony, two methods of PCM encoding

are widely used, A-Law and U-Law (also called Mu-Law or µ-Law). Typically U-Law is used in North America and a

few other locations while A-Law is used elsewhere. As well as setting the correct PCM encoding for the region, the

A-Law or U-Law setting of a system when it is first started affects a wide range of regional defaults relating to line

settings and other values.

Default Data Settings

When a new or defaulted control unit is switched on, it requests IP address information from a DHCP Server on the

network. This operation will occur whether the LAN cable is plugged in or not.

· If a DHCP server responds within approximately 10 seconds, the control unit defaults to being a DHCP client and

uses the IP address information supplied by the DHCP server.

· If no DHCP Server responds, the control unit still defaults to being the DHCP client but assumes the following

default LAN addresses:

· For its LAN1 it allocates the IP address 192.168.42.1 and IP Mask 255.255.255.0.

· For its LAN2 if supported, it allocates the IP address 192.168.43.1 and IP Mask 255.255.255.0.

· ! Once a control unit has obtained IP address and DHCP mode settings, it will retain those settings even if rebooted

without a configuration file present on the System SD card. To fully remove the existing IP address and DHCP mode

setting, the system must be defaulted using Branch Gateway Manager.

Default Security Settings

Security settings are held separately from the configuration settings and so are not defaulted by actions that default the

configuration. To return the security settings to their default values the separate Erase Security Settings command

should be used.

· A hunt group Main is created with extension number 200. The first 16 extensions on the systems are added to the

group.

· All physical extensions ports are numbered from extension number 201 upwards. A matching user record for each

extension is also created.

· A default incoming call route for all voice calls is created, with the default hunt group Main as its destination.

· A default incoming call route for data calls is created with the default RAS record DialIn as its destination.

· All lines are defaulted to Incoming Group ID and Outgoing Group ID of 0.

· Default short codes are created based on whether the system's locale is A-Law or U-Law. See Default Short Codes
