System Components: Physical Ports
10.12.15 WAN Port
This type of port 37-way D-type port is found on the rear of IP406 V2 and IP412 control units, and on the rear of the
WAN3 10/100 external expansion modules. For the Small Office Edition control unit an optional WAN trunk interface card
can be fitted.
Each WAN port supports a single synchronous data connection, which can be X.21, V.35 or V.24/V.28. Selection of the
required interface is determined by the cable plugged into the WAN port when power is applied.
•
WAN ports must be clocked externally, the IP Office does not provide a clock signal. The clock signal is usually
provided by the service provider but under some circumstances (for example laser, microwave or baseband modems)
extra provision must be made by the installer.
