·
You can configure more than one IPS in your PABX system.
·
You have one DSL connection that is not always available.
Here, you can configure the PABX system so that it automatically attempts to set up an Internet connection via DSL.
If this attempt is unsuccessful Internet connection via ISDN can be programmed using a different ISP.
·
You are using a provider that is not always available (some Internet-by-call providers have very reasonable rates, but
their access nodes are overloaded due to heavy traffic during peak times). Here you can simply configure several In-
ternet-by-call providers. The PABX system will automatically attempt to set up a connection with one of the
configured ISPs.
You can easily change the order of the ISPs with which the Internet connection is to be set up (»Fallback order« down / up). You can also set
the number of and intervals between these attempts at setting up an Internet connection for each ISP that has been configured. When the
waiting period between the attempts expires and when the configured number of actual attempts is reached and no connection has been
established, the next ISP in the list is selected.
Connection to the Internet is always set up automatically by the PABX system when a data packet is to be sent to the Internet. This occurs au-
tomatically when you enter http: //www. elmeg. de in your browser for example.
Billing of the costs is made through the telephone bill from your network provider.
Discontinuing an Internet connection
·
Click on the symbol for the »ControlCenter« in the task bar and select »Terminate connection to provider«.
·
After a set time (which can be defined), during which there is no data traffic to the Internet, the connection is termi-
nated automatically. You can activate/de-activate this function in the configuration.
If you set the parameter »Terminate on inactivity« too high, this may result is considerable costs for time-based
charges.
If you have a flat rate charge with your ISP you can set the parameter »Terminate on inactivity«. In this case the PABX
system will not automatically terminate the Internet connection, but will re-establish the connection if required (for
example B: after being disconnected by the ISP). If you have configured several ISPs, make sure that you make this set-
ting for the correct ISP entry in the ISP list!
Using a Fallback
Let's assume you have a DSL connection with the Deutschen Telekom AG (German Telecom) and have selected T-Online as your ISP.
You have configured three ISPs:
·
1. Internet access through T-DSL (T-online). The PABX system will use the PPPoE protocol at the WAN port. Enter
your access data (mark the ISP in the list, field »Edit«, field »Access data for T-Online«)
·
2. Internet access via ISDN (T-Online). The PABX system will use an ISDN dial-up connection (and the PPP proto-
col). Enter the same access data (mark the ISP in the list, field »Edit«, field »Access data for T-Online«).
·
3. Internet access using an Internet-by-call provider. The PABX system will use an ISDN dial-up connection (and the
PPP protocol). When you select an Internet-by-call provider from the defined list, the corresponding parameters are
already configured (»Access data«, »Number«).
If there is a disturbance with the DSL connection, the PABX system will, after a configured time period keep attempting to set up the Internet
connection for the number of times configured in the field »Number of connection attempts«. You can activate/de-activate this function in
the configuration. You can set the intervals between the attempts using the parameter »Time between attempts« in the configuration item
Network Internet. You can set the number of attempts and the interval between these attempts separately for each ISP that has been
configured.
After that, the PABX system will use the next ISP configured in the list for attempting to set up a connection.
If the connection is disrupted and an attempt is to be made later to re-establish the connection, this cycle is restarted beginning with the first
entry in the list.
