Installation and Setup

IPmux-1/1E needs no special tools for installation. A screwdriver is necessary when 
mounting IPmux-1/1E in a 19-inch rack. 

IPmux-1 internal jumpers and switches do not need to be configured by the user. 
Therefore, removing the product cover is not required.  

The IPmux-1E FXS/FXO/E&M version needs NO user internal jumper 
configuration. 
The IPmux-1E ISDN version contains jumpers that must be set for phantom feed 
(see 

). Open the case and verify the positions of internal jumpers before 

proceeding to the IPmux-1E installation, which is explained below. 

 

To open the IPmux-1E case:  
1.  Disconnect all the cables connected to the IPmux-1E. 
2.  Release the cover screws at the rear panel (one is near the POWER connector). 
3.  Slide the IPmux-1E top cover by pulling it straight out. 

 

To set the IPmux-1E ISDN-S module jumpers:  
If necessary, change the settings in accordance with the specific requirements of 
your application: 
•  ENA – enable phantom feed  
•  DIS – disable phantom feed 

The phantom feed ENA/DIS setting influences the IPmux-1E ISDN BRI operation 
mode. When phantom feed is disabled, the S-interface can be configured (through 
software) to the TE or NT mode. When phantom feed is enabled, only the NT 

mode is possible.
