COM Port
By installing the V.24 interface card a serial port on the COM interface is provided.
Please note: The connection line for the COM port can be up to three metres
long.
A PC for configuring the OpenCom 100 or transmitting call data can be connected to
the COM port. This call data can be evaluated in detail with the call charge registration
programme OpenCount.
LAN Port
Using the LAN port (Ethernet) you can integrate an OpenCom 100 into your corporate
network (local area network), and thus use it, among other things, as an IP router for
accessing the Internet.
LAN Ports on the Expansion Module of the OpenCom 130
The LAN ports of the Ethernet switches on the expansion module process Ethernet
data traffic with different degrees of priority. You should therefore assign the three
LAN ports on the expansion module as follows:
• LAN2: Use this port if you cascade a second communications system as a slave
system (see PBX Cascading starting on page 152).
• LAN1: Here connect the short Ethernet connection line to the basic module.
• LAN0: You should use the port with the lowest priority to connect to your cor-
porate network.
Both internal LAN ports of the Ethernet switch are reserved for usage on interface
cards.
