connection 

a1 and b1 are the incoming phone lines (e.g. outside line or private branch ex-
change).  
a2 and b2 are used to connect a phone in series. In idle state, they are connected 
to a1 and b1 via a loop current connector. a2 and b2 are disconnected as soon as 
the modem occupies the line. 
 
For the INSYS Modem 56k 4.1 UL, the following applies: 
Attention!  
All devices which are connected to a1, b1, a2 and b2, must comply with the re-
quirements of UL 60950-1, Section 6. The used phone cords must have the type 
AWG 26. 

The modem offers a choice of profiles: 

¾  Default factory setting: 

The default factory settings enable you to achieve a fixed 
defined basic state of the modem. Starting with this “ba-
sis”, you can customize the modem according to your re-
quirements. 

¾  User profiles 0 and 1: 

You can save configurations in the user profile, which may be 
re-used for certain purposes. 
A part of the S registry is saved in each profile. In the descrip-
tion, the affected registries are marked with an “*” in the S 
registry.
