3 Technical Overview At the center of the MMC system are Brandywine s powerful dual-redundant Master Clock Modules (MCM). Each MCM may be synchronized by a variety of reference sources and uses the selected reference to steer an embedded oscillator to provide stable and accurate time and frequency for the MMC. Multiple references can be prioritized with automatic failover. Uniquely, the MCM will also validate the GPS reference based upon the inherent stability of the MCM oscillator, providing hardening against possible GPS spoofing. Available input reference selections include GPS (both C/A code and SAASM receivers are supported), IRIG-B, Have Quick/1PPS and external 10 MHz. In additional an MCM may be synchronized to up to 2 other MMC chassis using a fiber optic crosslink, this provides additional resiliency for the MMC time and frequency references. The MMC supports multiple reference oscillator choices, including Rubidium (2U chassis only), Chip Scale Atomic Clock (CSAC) and Oven Controlled Oscillator (OCXO). The output signals for the Modular Master Clock System are generated by swappable Output Signal Modules (OSM), and are ideal for custom solutions or future expansion. Available modules include NTP, low-phase-noise frequency, time code modules such as IRIG A, B, G, H, and NASA 36, BCD, PPS, PPM, Have Quick as well as optical crosslink. The MMC status and control is via a full color touch screen that allows control of the local chassis, as well as remote chassis that are connected via crosslink. Other control options are via a Windows application, and via SNMPv3. User controls for the MMC are protected via password with encrypted storage. Network protocols also fully support privacy and authentication.

4 System Design with the MMC The MMC modular architecture concept allows the customer to configure complex timing and distribution systems around a combination of primary core modules that communicate and inter-link to create a custom timing solution. A hot swappable MCM (Master Clock Module) defines and generates the core time keeping function to which alternate inputs may contribute depending upon Stratum level and preferred configuration. For dual redundancy systems, two such MCM modules may be fitted and configured. Precision timing signals from the MCM are routed directly to rear panel connectors via a hot swap connection interface module which provide common timing signals such as 1PPS, IRIG B, 10MHz etc.. along with a choice of connectors. The choice and routing of these signals is programmable. The internal MCM timing signals are simultaneously routed to the expansion slots where Universal Output Signal Modules (OSMs) can be fitted in order to derive additional programmable system timing signals. These OSMs are also hot swappable and are available with a selection of common timing functions and rear panel connectors to deliver functionality such as NTP, Low Phase Noise Analogue (LPN), Telecoms E1/T1 and Universal timing and time code signals. A fiber optic crosslink module is available to facilitate multiple Master Clock system integration to provide Stratum 1 peer to peer functionality and dual redundancy with enhanced failure detection. Alternatively, the fiber link can be used to create a Master Clock System with Synchronised Slave clock timing and distribution system. When used as a duplex connection, the fiber optic crosslink provides seamless and automatic propogation delay compensation. The schematic below illustrates the base unit MMC concept :- MMC: DS15 Rev 1 - June 18 - Page 4 of 12

5 System Design with the MMC System design with the MMC core provides a number of key advantages. First and foremost is the inherent timing accuracy which can be dual redundant and seamlessly transferred across system boundaries to slave devices. Accuracy from an ideal source has been verified to within 3ns (2 Sigma). With a common platform and set of control tools, timing system components are readily interchanged, adapted or updated, thereby ensuring a system designed today, is fit for the evolving requirements of tomorrow.

6 System Design with the MMC System design with the MMC inherently provides cyber security hardened features that have been thoroughly tested and proven against determined military level attacks. GPS integrity monitoring along with hardware isolated and locked down communications ports all contribute to making the MMC one of the most secure timing devices available. Encrypted, password protection and user access is limited to the touch panel and/or a dedicated maintenance port via a choice of firmware enabled NTP, SNMP or MMCView protocols. Cyber Network Attack Scenarios NTP User ports are segregated from management and control ports Cyber attacks on NTP user ports cannot access the MMC control system. The maintenance port can be limited to front panel access only if required, thereby forcing manual intervention for a system change. High Security Areas Precise timing is often required on networks or in areas that are at a higher security level than the local master clock system. With individual NTP modules, the NTP ports are physically separated and are therefore able to serve multiple and physically separate networks with no cross network port access. The fiber optic crosslink maybe used in IA in which there is a one way, no return path for timing data. In this mode, propagation delays are pre-programmed allowing the MMC on one side of a security boundary to accurately and securely serve time to a slave MMC (SDU) across the boundary as indicated in the schematic to the right.

7 Master Clock Module (MCM) The Master Clock Module (MCM) is the oscillator at the heart of the Modular Master Clock (MMC) system. Master Clocks may use either one (standard) or two (optional) hot-swappable Master Clock Modules for redundancy and high availability operation. The MCM may configured with one of three types of oscillator, depending upon price/performance desired. The MCM is accessed either via the front touch screen display, an external Ethernet port, or a front panel maintenance Ethernet port. All aspects of the MMC operation are available through the front panel display. For MMC configurations where multiple chassis are connected via an optical fiber link, the status and configuration of a remote chassis can be accessed across this link. MCM s installed in a 2U chassis provide a number of signal outputs without the need to install any Output Signal Modules. Each MCM includes provision for Information Assurance. The front panel display is password protected, and the password is stored in encrypted form. Password requirements and updates are implemented by means of warning screens. All Network connections use both authentication and privacy corresponding to the protocol in use. Only required ports and protocols are enabled.

9 Universal Output Signal Module (OSM) The Universal OSM provides 4 outputs, each of which is user-programmable to a wide variety of time code or pulse outputs. This flexibility ensures that an MMC can be reconfigured as requirements change, and fewer modules are needed in comparison to designs where modules are single function. Time code outputs can be configured independently for local time. Passive rear transition modules are available for single ended BNC, or differential connectors. Each output is individually adjustable for propagation delay, ensuring that for high accuracy synchronization different cable lengths can be accommodated.

11 Optical Crosslink Module The Optical Crosslink Module is a unique feature of the MMC system. When installed, it allows a second MMC to be synchronized as a slave chassis. If both chassis have a primary reference installed (e.g. GPS) then the two MCM s can operate as peers. A Peering mode configuration provides additional redundancy, as well as providing additional references to detect failures. When a duplex cable is provided, the optical link provides seamless and automatic propagation delay compensation. A security mode allows the optical link to be operated in a single direction form Master to Slave over a single fiber.
