2.3 Installation and Setup
Setting Internal Jumpers
IPmux-1
IPmux-1 internal jumpers and switches do not need to be configured by the user.
Therefore, removing the product cover is not required.
IPmux-1E
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 Figure 2-1). 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 IPmux-1E.
2. Release all cover screws at the top and side panels.
3. Remove the IPmux-1E top cover by pulling it back.
 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.
