    Redundant System Operation 4.1 O VERVIEW The Comtech EF Data UT-4500 Series Up Converters are configured for redundant system operation using distributed protection switching in an active "Daisy Chain" configuration. Comtech EF Data's Proprietary "Daisy Chain" configuration distributes the converter protection switching functions in the converters.

  • Page 60: Backup Converter

    4.2.2 D ETACHABLE ODULES Comtech EF Data's converters are designed with a detachable Input/Output Module (IOM) which contain the signal path connectors. The IOM is utilized for single thread operation, or for testing of the unit. For redundant "Daisy Chain" operations, the on-line up converters are provided with a detachable Transmit Switch Module (TSM) replacing the IOM.

    UT4500 Series Up Converter MN/UT4500.IOM Remote Control Revision 2 4.4.2 A UTOMATIC ONFIGURATION ERIFICATION The backup converter has a menu that allows the operator to choose, on a converter-by- converter basis, manual (M) or automatic (A) operating mode. Figure 30 shows the system configured for automatic (A) operation. In this mode, failure of an online converter will automatically cause a switchover to the redundant unit to occur.

    UT4500 Series Up Converter MN/UT4500.IOM Remote Control Revision 2 4.4.4 O FFSET DJUSTMENT The offset is used to compensate for cable and switch losses. When the system is initially set up and tested, each converter needs to be forced to backup and the offset adjusted to minimize gain mismatch between the normal and bypassed mode.

    Chapter 6. Theory of Operation 6.1 A PPLICATIONS This appendix contains a general description of the theory of operation for the Model UT-4500 Series Up Converters. The UT-4500 Series Up Converters are used for SCPC, DAMA AND TDMA, as well as for full transponder HDTV and analog TV, applications. The converter operates over the RF frequency range with a typical gain of 35 dB.

    UT4500 Series Up Converter MN/UT4500.IOM Theory of Operation Revision 2 The "Daisy Chain" configuration is designed to chain the IF input and RF output of up to twelve (12) on-line converters together through TSM's terminating in a backup converter. When a fault occurs in an on-line converter, the TSM in the converter with the fault is commanded to switch to the backup converter.
