Figure 1-1. MCDD-100 MetaCarrier Detection Device Comtech EF Data’s MCDD-100 MetaCarrier® Detection Device (Figure 1-1) is a patent pending carrier identification (CID) product that uses spread spectrum technology to decode an embedded unique carrier identification sequence for a transmission carrier.
MCDD-100 MetaCarrier Detection Device Revision 3 Introduction MN-MCDD100 Functional Description Figure 1-2. MCDD-100 Connection Example The MCDD-100 supports both L-Band operation (950 MHz to 2150 MHz) and IF operation (50 MHz to 180 MHz). Note that the MCDD-100 does not provide DC power for a Low-Noise Block Downconverter (LNB) for the L-Band input.
Page 17
MCDD-100 MetaCarrier Detection Device Revision 3 Introduction MN-MCDD100 Detection of the presence of the MetaCarrier is initiated in the MCDD-100 by searching, using digital signal processing techniques, for one of two possible MetaCarrier chip rates. These MetaCarrier chip rates are as follows: Host Carrier Embedded MetaCarrier ≥512 ksps...
The time and costs associated with such methods are significant. By contrast, Comtech EF Data’s CID products provide the operator with the interference source’s identification information within minutes. Once the offending carrier is identified, appropriate action can be taken to shut down or otherwise remove the identified transmission from service.
MCDD-100 MetaCarrier Detection Device Revision 3 Introduction MN-MCDD100 1.2.2 Compatibility The MCDD-100 is compatible with any L-Band or 70/140 MHz carrier supporting up to 64 Msps that is transporting a MetaCarrier. Sect. 1.4.1 Product Feature Specifications MCDD-100 Features 1.3.1 Physical Description The MCDD-100 is constructed as a 1RU-high rack-mounting chassis.

MCDD-100 MetaCarrier Detection Device Revision 3 Serial-based Remote Product Management MN-MCDD100 5.2.2 Packet Structure The exchange of information is transmitted, Controller-to-Target and Target-to-Controller, in ‘packets’. Each packet contains a finite number of bytes consisting of printable ASCII characters, excluding ASCII code 127 (DELETE). In this context, the Carriage Return and Line Feed characters are considered printable.
MCDD-100 MetaCarrier Detection Device Revision 3 Serial-based Remote Product Management MN-MCDD100 5.2.2.1 Start of Packet Controller-to-Target: This is the character ‘<’ (ASCII code 60). Target-to-Controller: This is the character ‘>’ (ASCII code 62). The ‘<’ and ‘>’ characters indicate the start of packet. They may not appear anywhere else within the body of the message. 5.2.2.2 Target Address In EIA-232 applications, this value is set to 0000.

MCDD-100 MetaCarrier Detection Device Revision 3 Appendix A MN-MCDD100 As before, 50% probability is assumed, since the MCxD-100 must achieve code phase- lock to obtain the Carrier ID from the MetaCarrier. Therefore, each time the MCxD-100 is instructed to reacquire, the probability remains that it will achieve code phase-lock to the interfering carrier.
