PCs with Windows operating system can be called back only via the CBCP.
So that a calling number could be additionally checked in the
ELSA LANCOM
Business , the following values are available in the name list for the callback
entry.
The 'Name' setting provides the highest level of security when an entry is not
only configured in the numerical list, but also in the PPP list. The 'ELSA'
setting provides the quickest callback method between two ELSA routers.
With Windows remote stations, the 'Name' setting must be selected.
Callback using Microsoft CBCP
With Microsoft CBCP, the callback number can be determined in various
ways.
The called party does not call back.
With this entry... ...the callback is thus entered:
Off No callbacks.
Auto (not Windows 95,
Windows 98 or Windows
NT, see below) The remote station will be called back if so specified in the name list. At first, the call
is denied and as soon as the channel is clear again, it is called back (duration is
approx. 8 seconds). If the remote station is not found in the numerical list, it is first
accepted as the DEFAULT remote station, and the callback is negotiated during the
protocol negotiation. Thus a one-unit charge is applied.
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). Thus a one-unit charge is applied.
ELSA When the remote station is found in the numerical list, a quick callback is carried out,
i.e., the
ELSA LANCOM Business 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 immedia-
tely after the signal, then after two seconds the situation reverts back to normal call-
back procedures (duration is once again approx. 8 seconds). This procedure is only
available with 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 'ELSA'.
