19  VoIP Subscriber Gateways 
 
  2 DEVICE CONFIGURATION VIA WEB-INTERFACE. ADMINISTRATOR ACCESS 
The  device  configuration  is  shown  by  example  of  TAU-8.IP-W. Configuration  of  TAU-4.IP  and 
TAU-8.IP is performed in a similar way. 
Connect  to  the  device  via  WAN  interface  by  using  web-browser  (explorer  for  hypertext 
document) such as Firefox, Opera and Chrome. Enter IP-address of the device into the browser string. 
The default IP-address of the device - 192.168.1.2, subnet mask - 255.255.255.0. Gateway 
will receive IP-address automatically by using DHCP protocol in the default configuration 
(beginning with software version 2.0.0). Voice menu provides control of the received IP-
address (See Appendix A for more details). 
After entering IP address the device will request username and password. 
 
Initial startup username: admin, password: password.  
There are three user types for the device: admin, user and viewer. User admin (administrator, 
default  password:  password)  has the  full  access  to  the  device:  read/write  any  settings,  full  device 
status monitoring.  User  user  (non-privileged  user, default  password:  user) may  configure PPPoE in 
order to connect to the Internet, may not access the device status monitoring. User viewer (spectator, 
default  password:  viewer)  may  only  view  full  device  configuration  without  editing  privileges;  may 
access full device status monitoring. 
The  ‘Information’  menu  of  the  ‘System’  submenu will  open  after  getting  access  to  the  web-
configurator. Navigation elements of the WEB-configurator are shown on Fig. 6.
