7.13 Data Lines to the Remote Diagnostics
System
Remote diagnostics can be realized via different mediums, each sub-
ject to different rules.
7.13.1 Analogue Telephone Line
If remote diagnostics are to be carried out via an analogue telephone
connection, the data is transmitted via an analogue modem, which
can be connected to the USB-A slot of the BP308. This has to be a
"real" hardware modem and not a software modem. The USB
modems for the bp306 supplied by BÖHNKE + PARTNER are "real"
hardware modems. The modem must also support the V.250 stand-
ard. If more than one control unit is allocated to a joint telephone out-
let or if there is an emergency call system that uses this analogue
telephone outlet as well, you have to use an emergency call manager
(refer to the "Connection of the Emergency Call System" section).
7.13.2 ISDN
If there is an ISDN connection available for the data remote dia-
gnostics, the integrated ISDN module (option ISDN) is used or an
external ISDN interface.
7.13.3 Ethernet
If data remote diagnostics is to be carried out via an Intranet or the
Internet, an Ethernet interface is usually available in the machine
room. Use the integrated Ethernet module of the bp308 in this case .
