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.

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.
