The Sonet System was designed and engineered so that anyone could quickly unpack and set up the system. It comes with a Volume Control Unit that plugs into any standard wall outlet. Wiring is as simple as connecting modular telephone cords between the Volume Control Unit and Emitters. Thin plastic plates can be attached to the wall using a small screw, and Velcro is used to hold the Emitters to the plastic plates. The Sonet System speakers can also be placed on your desk. Each volume control unit can support up to six emitters. A basic Sonet System comes with two emitters, and can treat a room or office of up to 120 sq. ft. For rooms or offices larger than 120 sq. ft., add at least one emitter for each additional 75 sq. ft. The Sonet Extension Kit offers addional speakers for the Sonet system. Each Sonet System comes with: * 1 - Controller with volume dial * 2 - Emitters (speakers) * 2 - 8' cables to connect the emitters to the controller * 1 - Transformer that plugs into a standard AC wall outlet * 1 - Set of mounting hardware, including mounting plates with push pins for mounting on fabric-covered walls * Wiring lips, and spare Velcro pairs Sonet System Specifications: ?

For those wanting the protection of a Complete Home Security Alarm System but lacking a land line telephone. The AAS Cellular Alarm System consists of a Wireless Home Security Alarm System matched a with Cellular Gsm Terminal operationing on all major world band frequencies. This GSM Alarm System is perfect for vacant and weekend homes,construction sites....anywhere with power but no phone line. Self monitored. No fees or contracts. Expandable [to 96 sensors]and portable. The GSM Alarm System operates on all major world band cellular frequencies: 1. GSM 850 mhz/900mhz/1800mhz/1900mhz 2.GSM 900mhz/1800mhz 3. CDMA 800 MHz The GSM Terminal replaces the typical landline and works like a cell phone. As most mobile phones utilize a SIM card to wirelessly transmit through the cellular network so does the Cellular GSM Terminal. SIM cards may be purchased as a prepaid card or on a monthly basis from your cellular carrier such as AT&T and T-Mobile. The GSM Alarm System comes with a built-in backup battery pack and the GSM Terminal has the option of a UPS Back-up Battery power adapter to maintain continuous fuctioning in case of power outages and interruptions. The GSM Alarm does not interfere with Wi-Fi applications. The Cellular Alarm System will call to mobile phones, landline phones and broadband phones. The Cellular Alarm System comes with an integrated Automatic Dialer with a stored memory capacity for six phone numbers[up to 21 digits in length] and for a recorded message. When the Wireless GSM Alarm System is triggered it will call each of the pre-stored numbers and deliver the pre-recorded message. When the system calls, the receiver will be able to listen and monitor the premises through the phone. Minimize

Fiber-optic communication systems have revolutionized our t ... Read more

Fiber-optic communication systems have revolutionized our telecommunication infrastructures – currently, almost all telephone land-line, cellular, and internet communications must travel via some form of optical fibers. In these transmission systems, neither the phase nor frequency of the optical signal carries information – only the intensity of the signal is used. To transmit more information in a single optical carrier, the phase of the optical carrier must be explored. As a result, there is renewed interest in phase-modulated optical communications, mainly in direct-detection DPSK signals for long-haul optical communication systems. When optical amplifiers are used to maintain certain signal level among the fiber link, the system is limited by amplifier noises and fiber nonlinearities. Phase-Modulated Optical Communication Systems surveys this newly popular area, covering the following topics: - The transmitter and receiver for phase-modulated coherent lightwave systems - Method for performance analysis of phase-modulated optical signals - Direct-detection DPSK signal with fiber nonlinearities, degraded by nonlinear phase noise and intrachannel effects - Wavelength-division-multiplexed direct-detection DPSK signals - Multi-level phase-modulated optical signals, such as the four-phase DQPSK signal. Graduate students, professional engineers, and researchers will all benefit from this updated treatment of an important topic in the optical communications field. Minimize
