  1.0 Introduction

Figure 1. Sample Scenario Using the STE for Type-1 Encryption

This document describes how to configure a KlasTA on the Mobile Side connected to a STE to dial a 128K ISDN call, as shown in Figure 1. The Mobile Side represents a user in a deployed environment and the Home Side represents a fixed terrestrial network with an established ISDN BRI connection. Since the STE has built-in 128K ISDN capability, it can be used in conjunction with KlasTA to initiate an ISDN call through two separate M4 INMARSAT Terminals. When initiating the connection, the STE will send the dial string to the KlasTA. The KlasTA will then relay the dial string on to each of the M4 Terminals in order to establish the satellite connection. Once a secure connection is made with the Home Side STE, the KlasTA will act as a splitter in order to divide the 128K output from the STE into two separate 64K channels for transmission over each of the M4 Terminals.

  2.0 Cable Connections

Prior to beginning, ensure the following cable connections have been properly secured:

  1. Power cord is plugged in and KlasTA is on.
  2. Control Port Cable is connected to the PCs serial port.
  3. Control Port Cable is connected to the ‘Control’ port on the front of the KlasTA.
  4. ISDN cable is connected from the RJ-45 ISDN Output port on the STE to the RJ-45 ISDN Input Port on the KlasTA.
  5. ISDN cables are connected from the RJ-45 ISDN Output Ports 1 and 2 on KlasTA to the RJ-45 S/T Input Ports on each of the M4 Terminals.

  3.0 Configure the STE

The STE has a specific sequence of settings that allow it to encrypt data using the RS-530 serial data port. Follow the instructions from Klas Application Note Q100012 in order to configure the STE so that it will work properly with KlasTA. Given the sensitive nature of Type-1 documentation, please contact a Klas Technical Support Representative for this Application Note.

  1. Review the configuration options to ensure they are correct and then click on the ‘Configure’ button to initiate the configuration sequence on the KlasTA.

Figure 7. KlasTA Configuration Summary Screen

  1. If required, KlasTA may initially erase and reflash the firmware needed to support the new KlasSplitter firmware, as shown in Figure 12. Once the firmware change is complete, the configuration settings will be loaded into KlasTA, as shown in Figure 13. Click on the ‘OK’ button once the configuration sequence has successfully completed.
