2.5 Installation and Setup

Setting 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 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.
