holding time of 0 seconds then. However, connections interrupted by the
remote site are not automatically re-established with this setting.
With a holding time of 9,999 seconds the connection is always re-established
after any disconnection. Additionally, the connection is re-established after a
reboot of the device (’auto reconnect’).
7.8 Callback functions
The LANCOM supports automatic callback via its ISDN port.
In addition to callback via the D channel, the CBCP (Callback Control Protocol)
specified by Microsoft and callback via PPP as per RFC 1570 (PPP LCP exten-
sions) are also offered. There is also the option of a particularly fast callback
using a process developed by LANCOM. PCs with Windows operating system
can be called back only via the CBCP.
7.8.1 Callback for Microsoft CBCP
With Microsoft CBCP, the callback number can be determined in various ways.
̈ The party called does not call back.
̈ The party called allows the caller to specify the callback number itself.
̈ The party called knows the callback numbers and only calls these back.
Via CBCP, it is possible to establish connection to the LANCOM from a PC with
Windows operating system and also to be called back by this PC. Three pos-
sible settings are selected in the name list via the callback entry as well as the
calling number entry.
