Two relay ports that allow externally powered circuits to be controlled via a single 3.5mm stereo
jack socket.
• DC Power I/P Socket

• DTE Port
A 9-way D-type socket. Used for connection to PCs, servers and EFTPOS terminals.

The trunk interface modules are fitted into either Slots A or B as follows:
• Slot A
• Quad Analog: 4 trunks
• Quad BRI: 8 trunks
• Single or Dual PRI E1/E1-R2: 30 or 60 trunks respectively
• Single or Dual PRI T1: 24B/ 23B+1D or 48B/46B+2D trunks respectively.
• Slot B
• Single or Dual PRI E1/E1-R2: 30 or 60 trunks respectively
• Single or Dual PRI T1: 24B/ 23B+1D or 48B/46B+2D trunks respectively.
• PRI T1trunks support both ISDN and Analog emulation. The default setting is 23B+1D
(46B+2D) and is switchable in the installation software to become a 24B (48B) trunk. See
Integral Module Kits
for country specific variants.
• 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 supplied Network Terminating Unit (NTU) via the appropriate X.21/V.35
/V.24 cable. This interface is identical to those on the WAN3 Expansion Module.
• Expansion Ports 1-12
Used to provide access to either optional Expansion Modules which allow the IP412 Office to be
expanded to 256 extensions or additional WAN interfaces.
• Audio I/P Socket
A single 3.5mm stereo or mono jack socket that enables input from an external 'Music-on-Hold'
source.
