Avaya 40DHB0002USCL 사용자 설명서

The IP412 Office system platform supports up to 256 extensions. Connection to trunks is via a 

combination of any of the following integral interface modules :- 

 - Single or Dual PRI E1/PRIE1-R2 (30 or 60 trunks respectively)  

 - Single or Dual PRI T1 (24 or 48 trunks respectively - USA only)   

 - Quad BRI (8 trunks)  

 - Analog 4 (4 loop start trunks)  
See page 39 for installation and page 32 for country specific variants. 
Dual independent auto-negotiating 10/100 BaseT Ethernet ports provide segmented access (allows a 

firewall break to be used) to the LAN.  

(Where IP telephones are to be used a suitable switch, e.g. an Avaya Cajun P130, must be used.) 

Optional Expansion Modules (see page 27) allow the IP412 Office to be expanded to a maximum of 

256 digital or analog extensions. The Expansion 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 twelve, in any combination, of the following Expansion Modules can be supported by the 

IP412 Office base unit provided that the maximum number of extensions does not exceed 256. 
•  IP400 Digital Terminal 16/30 or Digital Station 16/30 

IP400 Digital Terminal/Station modules can be fitted to allow a maximum of 256 digital 

extensions, e.g. eight equipped  with 30 extensions and the ninth with sixteen extensions. 

•  IP400 Phone 8/16/30 

Hence, nine IP400 Phone modules can be fitted to allow a maximum of 256 analog extensions, 

e.g. eight equipped  with 30 extensions and the ninth with sixteen extensions. 

•  IP400 So8 

•  IP400 WAN3 

These expansion modules are connected to the IP403 Office unit via one of the LAN Ports 

located on the front of each unit. 

•  IP400 Analog Trunk 16 

Provides support for up to 16 Loop Start or Ground Start analog trunks (see page 31). Two power 

fail sockets are also provided. 

 

In addition the IP403 Office can be fitted with either or both of the following optional Integral Modules 

(see pages 40 and 41): 
•  Voice Compression Module (VCM) 

Provides VoIP applications (using Avaya 4600 IP series telephones connected via LAN ports).  

Available in 5, 10 and 20 channel variants. 

•  Dual Modem Module 

Allows termination of two simultaneous analog modem calls at speeds up to and including 56kbps 

(V.90).
