The setting 'Name' offers the greatest security when an entry is made
into the number list as well as the PPP list. The setting 'LANCOM'
offers the fastest callback method between two LANCOM routers.
With Windows remote stations, the 'Name' setting must be selected.
7.9 Channel bundling with MLPPP
When establishing an ISDN connection to a remote station with PPP capabil-
ity, you can transmit data more quickly. Data can be compressed and/or sev-
eral B channels can be used for data transmission (channel bundling).
Connecting with cable bundling is distinguished from “normal” connections
in that not only one, but rather several B channels are used parallel for data
transmission.
MLPPP (Multilink PPP) is used for channel bundling. This procedure is of
course only available when PPP is used as the B-channel protocol. MLPPP is
used e.g. for Internet access via Internet provider, which also operate remote
stations with MLPPP capability from your direct dialing nodes.
'Name' Before a callback occurs, a protocol negotiation is always carried out
even when the remote station was found in the numerical list (e.g. for
computers with Windows having direct dialing on the device). Here
only minor charges result.
'LANCOM' When the remote station is found in the numerical list, a quick call-
back is carried out, i.e., the LANCOM sends a special signal to the
remote station and calls back immediately when the channel is clear
again. After approx. 2 seconds, the connection is established. If the
remote station does not take back the call immediately after the sig-
nal, then after two seconds the situation reverts back to normal call-
back procedures (duration is once again approx. 8 seconds). This
process is only available for DSS1 connections.
'Looser' Use the 'Looser' option when a callback is expected from the remote
station. This setting carries out two functions simultaneously. On the
one hand, it ensures that a custom connection setup is taken back
when there is an incoming call from the called remote station, and on
the other hand, the function is activated with this setting to be able to
react to the rapid callback procedure. In other words, in order to be
able to use rapid callback, the caller must be in the 'Looser' mode
while the party being called must discontinue callback with 'LAN-
COM'.
