Avaya 40DHB0002USCL Manual Do Utilizador

The IP403 Office system platform supports up to eight digital and two analog telephones. This can be 

expanded, by use of extension modules, to 100 extensions.  

Two variants are available and are equipped as follows: 

•  DT ports  - Support Avaya 2000 series telephones. 

•  DS ports  - Support Avaya 6400 and/or Avaya 4400 series telephones. 
Both ports can be set for either 

µ-Law or A-Law PCM encoding. At default DT ports are set to A-Law  

and DS ports are set to 

µ-Law. However, these can be switched in software (refer to the 

Administration Manager Manual for details). 

Connection to trunks is via one* of the following integral interface modules:- 

 Single PRI E1 (30 trunks) or Single PRI T1 (23B+1D or 24B trunks - USA only) or 

 Quad BRI (8 trunks) or Analog 4 (loop start trunks ). 
 If Analog 4 modules are used, a second module can be fitted in Slot A. 
See page 39 for installation and page 32 for country specific variants. 
An eight port auto-negotiating 10/100 BaseT LAN hub provides access to networks and/or up to eight 

IP telephones. (Where IP telephones are to be used, the hub should be connected to a suitable 

switch, e.g. an Avaya Cajun P130.) 

Optional Expansion Modules (see page 27) allow the IP403 Office to be expanded to 100 

extensions. These modules (with the exception of the WAN3 – see below) are connected via the 

Expansion Port sockets that are located on the back of each unit. Up to 3, in any combination, of 

the following Expansion Modules can be supported by the IP403 Office base unit. 
•  IP400 Digital Terminal 16/30 or Digital Station 16/30 

extension modules are IP400 Digital Terminal/Station 30s, then the maximum of 100 extensions 

will consist of 90 digital extensions, plus the base unit's 2 analog extensions and 8 digital 

extensions. 

•  IP400 Phone 8/16/30 

extension modules are IP400 Phone 30s, then the maximum of 100 extensions will consist of 90 

analog extensions, plus the base unit's 2 analog extensions and 8 digital extensions. 

•  IP400 So8 

•  IP400 WAN3 

Provides support for a further 3 digital leased line (WAN) connections (see page 30). These
