IP400 WAN3
•
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 is required for connection to an IP403 or IP406. An
IP412 requires a LAN Crossover cable.
•
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 WAN ports are identical to those on the IP403/406/412 control
units.
