The IP412 Office base unit supports up to 360 extensions by using up to12 Expansion 
modules. 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 40 for installation and page 28 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 LAN switch with QoS capabilities, must be 
used.) 

Optional Expansion Modules (see page 23) allow the IP412 Office to be expanded to a 
maximum of 360 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 360. 
•  IP400 Digital Terminal 16/30 or Digital Station 16/30: Two variants of both (for 16 or 

30 extensions) for digital telephones (see page 23). Hence, twelve IP400 Digital 
Terminal/Station modules can be fitted to allow a maximum of 360 digital extensions. 

•  IP400 Phone 8/16/30: Three variants (for 8, 16 or 30 extensions) for analog 

telephones (see page 24). Hence, twelve IP400 Phone modules can be fitted to allow a 
maximum of 360 analog extensions. 

•  IP400 So8: An S-bus module that provides 8 Basic rate ISDN interfaces  

•  IP400 WAN3: Provides support for a further 3 digital leased line (WAN) connections 

(see page 26). 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 

 

In addition the IP412 Office can be fitted with either or both of the following optional 
Integral Modules (see pages 41 and 42):

in 5, 10, 20 and 30 channel variants. The IP412 Office can have two VCMs (of any 
type).
