  • Page 27: Functional Description

    1.3.1 Switch / Modem Operation The CRS-170A is configured with two modems to form a complete 1:1 redundant modem system. Within the CRS-170A, a redundancy controller continually monitors the status of faults for both modems to determine which modem should be Online and Offline. The control cables between the modems and the CRS-170A include four signal groups: •...
  • Page 28 Section 4.10 CRS-170A DIP Switch Settings Two green LEDs are located on the antenna side of the CRS-170A. They provide a visual identifier for the Online unit. With the ‘bridging’ architecture of the CRS-170A (whereby identical terrestrial data traffic signals are routed to both Online and Offline units), the redundancy controller can avoid unnecessary switchovers.

    Similarly, the SDM-300L3 requires an SMS-301 switch together with the CRS-170A. In both cases, the CRS-170A is controlled by the supporting data switch, and places the ‘A’ or ‘B’ modem RF Online to match the data switch state. The CDM-600L (CLM-9600L) modems supply redundant power to the CRS-170A through the CRS-150.
  • Page 38 Interface. Additionally, the CRS-170A provides further isolation and security by using an RF relay within the unit. The Rx IF signal is fed to both modems simultaneously through the power divider in the CRS-170A. This divider introduces a loss of approximately 3.5 dB but, given the wide dynamic range of the demodulator in the CDM-600L (CLM-9600L), this is not considered to be a problem.

  • Page 39: Operation With Sdm-300L3 Modems And Sms-301 Switch

    IF signals, 10MHz reference signals, DC power for the BUC and LNB, and FSK signaling to the BUC are switched in the CRS-170A under control of the SMS-301. In the case of equipment failure, automatic switching takes place to protect the traffic circuit.

    You must order terrestrial data interface components/kits separately. See Section 5.11.2 for CDM-700 terrestrial data interface configuration and connection examples and details. You must use the Comtech EF Data KT/12551 1:1 Redundancy Control/IF Interface Cabling Kit (Section 5.2.2) for your control and L-Band Unit-to-Switch cabling connections. See Section 5.11.1.1 and Figure 5-57 for the CDM-700 Modem-to-Switch Control Interface connection details.

    1) Excluding the modems, the KT/12551 CRS-170A L-Band 1:1 Redundancy Kit (Section 5.2.2) provides all components shown in Figure 5-57. 2) When you connect the Control Interface cables between the CRS-170A and the modems, make sure that you securely fasten the screw locks on the Type ‘D’ connectors. This prevents accidental disconnection of the cables, particularly when you are removing and replacing a standby unit.

  • Page 141: Modem-To-Switch If Interface Connection

    IMPORTANT: The Tx IF from ‘MODEM A’ connects to the Tx IF port ‘J5 | Tx A’ on the CRS-170A; similarly, the Tx IF from ‘MODEM B’ connects to the Tx IF port ‘J6 | Tx B’ on the CRS-170A. The same logic applies for the Rx IF connections. It is important to note that failure to observe this requirement will result in system malfunction.
