Port connections
• 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 kit).
• DTE Port
A 9-way D-type socket. Used for connection to PCs, servers and EFTPOS terminals.
• BRI/PRI/ALOG Ports
The trunk interface modules are fitted into either Slots A or B as follows:
Slot A Quad Analog: 4 trunks (see page 37 for grounding)
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
(see page 37 for grounding).
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
(see page 37 for grounding).
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 page 39 for installation, page 33 for country specific variants and page 37 for grounding.
• 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
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).
• Expansion Ports 1-12
Used to provide access to either:
- optional Expansion Modules which allow the IP412 Office to
be expanded to 256 extensions (see page 22).
- additional ISDN or 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.
Port Pinouts and Cables
For Port Pinouts and Cables, refer to pages 51 and 55 respectively.
