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 35 for grounding)
Slot B - Single or Dual PRI E1/E1-R2: 30 or 60 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 page 40 for installation, page 29 for country specific variants and page 35 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 /V.24 cable. See pages
74, 75 and 76 for cable details and page 66 for port details. These interfaces are
identical to those on the WAN3 Extension Module (see page 26).
• 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 18).
- 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.
