PINOUT FOR THE CONNECTORS 

 

The SS-15 BRI (ISDN 2 GSM) features four 
data connectors at the bottom of its case. All 
connectors are of the same type, female RJ-
45, but they have different functions. Please 
read the paragraph carefully and perform the 
connections accordingly. 

 

 

 

 

Serial connector 
 
For programming the SS-15 BRI (ISDN 2 GSM) the special connection cable 
must be used. The special serial cable is included in the package of the SS-
15 BRI (ISDN 2 GSM) equipment.  
The end towards the SS-15 BRI features an RJ11 connector while the end 
towards the COM port of the computer features a standard female DB-9 
connector.  
In the drawing below the pin numbering can be seen (from left to right) of the 
RJ11 female connector of the SS-15 BRI and the corresponding male RJ11 
male connector on the serial programming cable.

TE connector – used for connecting the SS-15 BRI TE interface. 
 
The TE interface of the SS-15 BRI (ISDN 2 GSM) unit is used for connection 
to NT interfaces of the ISDN private branch exchange or of the ISDN public 
telephony network. TE interfaces are provided with embedded termination 
resistors. These resistors may be enabled by means of corresponding 
jumpers, the pair JAT1 and JAT2.
