Port connections
• LAN Port
The LAN Port is the expansion port and permits connection to an IP403, IP406 or IP412 Office
platform LAN Port. A LAN Interconnect cable (see page 58) is required for connection to an IP403
or IP406 and an IP412 requires a Crossover cable (see page 60).

Port connections
• WAN Ports
These ports support a single synchronous data connection, which can be X.21, V.35 or
V.24/V.28. 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. These cables are detailed in the table below (see pages 62, 63 and 64
for details).
Cable Type SAP Code
V.24/V.28 Cable 700213416
V.35 Cable 700213408
X.21 Cable 700213424
These WAN ports are identical to those on the IP403/406/412 Office platforms (see pages 16, 20
and 24).
• DC Power I/P Socket
Socket for the external 24V DC unregulated power supply (supplied with kit).
