 Audio I/P Socket 

 

•  External O/P Socket 

Two relay ports that allow externally powered circuits to be controlled via a single 3.5mm stereo 

jack socket. 

•  DC Power I/P Socket 

Socket for the external 24V DC unregulated power supply (supplied with equipment). 

•  DTE Port 

A 25-way D-type socket. Used for connection to PCs, servers and EFTPOS devices or terminals. 

The trunk interface modules are fitted into either Slot A or Slot B as follows: 

Slot A   Quad Analog: 4 trunks (see page 37 for grounding)  

Slot B   Quad Analog: 4 trunks (see page 37 for grounding)  

 

PRI E1/PRI E1-R2: 30 trunks  

 

 

Quad BRI: 8 trunks. 

PRI T1 trunks support both ISDN and Analog emulation. The default setting is 23B+1D and is 

switchable in the installation software to provide 24B trunks. 

•  WAN Port 

This port supports a single synchronous data connection, which can be X.21, V.35 or V.24. The 

selection of the required interface is automatically determined from the pin-out of the cable 

plugged into the ‘WAN’ port. This cable must be connected before power is applied for auto 

detection to work. Connection to a Digital Leased Circuit is made by connecting the WAN port on 

the rear of the unit to the existing Network Terminating Unit (NTU) via the appropriate X.21, V.35 

or V.24 cable.  
See pages 62, 63 and 64 for cable details and page 54 for port details. These interfaces are 
identical to those on the WAN3 Extension Module (see page 30). 

•  USB Interface 

Used for connection to a PC or server, allowing it to utilize the IP403 Office as a Terminal Adapter 

(TA). (Before installing the USB software on your PC you must read the instructions supplied 

with the installation software - refer to the USB Installation Manual for details). 

•  Expansion Ports 1-3 

Used to provide access to the optional Expansion Modules (see page 27) which allow the IP403 

•  Audio I/P Socket 

A single 3.5mm stereo or mono jack socket that enables input from an external 'Music-on-Hold' 

source.
