can answer an incoming call with a callback or request a callback from a connection part-
ner. Identification can be based on the calling party number or PAP/CHAP/MS-CHAP au-
thentication. Identification is made in the former case without call acceptance, as the calling
party number is transferred over the ISDN D-channel, and in the latter case with call ac-
ceptance.
Connection Idle Timeout
The connection idle timeout is determined in order to clear the connection automatically if it
is not being used, i.e. if data is no longer being sent, to help you save costs.
Block after Connection Failure
You use this function to set up a waiting time for outgoing connection attempts after which
your device's connection attempt is regarded as having failed.
Channel Bundling
Your device supports dynamic and static channel bundling for dialup connections. Only one
B-channel is initially opened when a connection is set up.
Dynamic
Dynamic channel bundling means that your device connects other ISDN B-channels to in-
crease the throughput for connections if this is required, e.g. for large data rates. If the
amount of data traffic drops, the additional B-channels are closed again.
Static
In static channel bundling, you specify right from the start how many B-channels your
device is to use for connections, regardless of the transferred data rate.
Channel bundling can only be used for ISDN connections for a bandwidth increase or as a
backup. If devices from other manufacturers are to be used at the far end, ensure that
these support dynamic channel bundling for a bandwidth increase or as a backup.
14.1.1 PPPoE
A list of all PPToE interfaces is displayed in the WAN->In Dialup->PPPoE menu.
PPP over Ethernet (PPPoE) is the use of the Point-to-Point Protocol (PPP) network pro-
tocol over an Ethernet connection. Today, PPPoE is used for ADSL connections in Ger-
many. In Austria, the Point To Point Tunnelling Protocol (PPTP) was originally used for AD-
