Introduction
Router of the PABX elmeg T444 / elmeg T484
The PABX elmeg T444 / elmeg T484 is equipped with an integrated router. You can provide access to the Internet and
network several PC via this router.
What is a router?
A router allows LAN clients (computers, PC within a network) of one network (LAN) to obtain access to a different
network, for example Internet. Access to the Internet is made available by various Internet service providers (ISP).
In this process, the router searches for a path on which data can be exchanged between the LAN clients in the local
network and the Internet. Linking to the Internet can be carried out via an xDSL and / or an ISDN connection.
Router of the PABX system
The PABX system router is equipped with a WAN/xDSL and a LAN port). The PABX system is connected to another
network, for example the Internet, via the WAN/xDSL port. You can hook up a DSL or cable model for connection to
the Internet.
The LAN ports are for your local network. Here, you can directly connect up to two PCs equipped with built-in net-
work cards. If you wish to network more than two PCs you can do this using an additional HUB / Switch, HomePN
(optional module, not included in standard supply scope of system), or a USB port.
LAN1 sets itself automatically (from 10 Mbit/s half-duplex up to 100 Mbit/s full duplex) to the maximum data trans-
fer rate of the remote location (PC).
These PCs are also part of your local network and can, for example, exchange files or take advantage of the Internet
connections via the router. All LAN clients that are linked are integrated into the local network via the TCP/IP proto-
col.
Further PCs can be linked to your network via RAS- access. Here, the IP address is always assigned by the telephone
system, even when the DHCP server is de-activated. Under “Address assignment” in the configuration program you
can de-activate the DHCP server and input the starting address for RAS. The following 11 IP addresses are then auto-
matically reserved for RAS.
Using the Remote Access Server (RAS) a field representative, for example, can call into the local network from an ex-
ternal location and then via the local network access the Internet. Access from an external location is only possible via
an ISDN connection. External access is provided with user-name and password protection. If the call is made from an
external location only, the phone number can also be monitored as an added protection feature. Note that this access
portal is not protected by a firewall!
Note
Please note the further instructions given in the operator’s manual of the PABX system for connecting a pcs.
Which Internet connections are supported?
You can set up a connection to the Internet with your PABX system as follows:
·
Dial-up connections via ISDN (using PPP protocol, with one or two ISDN B channels, i.e. at 64 kbit/s or 128
kbit/s).
These types of connections require access data with the number to be dialed, the user name and password
and, in some cases, other information such as the IP address of the name server and any information about
the data compression method that is used (VJH).
·
Using xDSL (for example ADSL - T-DSL) in conjunction with a DSL modem that is compatible with your
ISP via PPPoE.
These connections require your user name and password as access data.
