TAS 1200D In Stock

The TAS 1200D by Spirent is a Series II Digital Telephone Network Emulator designed to test various devices that communicate through the Public Switched Telephone Network (PSTN). It offers comprehensive testing capabilities for devices such as modems, remote access servers, fax machines, and subscriber voice/data equipment. With its versatility and broad range of applications, the TAS 1200D is well-suited for product development, design verification testing, production testing, product evaluation, quality assurance, standards conformance, and competitive analysis.

One of the key features of the TAS 1200D is its ability to simulate a wide array of transmission impairments and signaling conditions within a laboratory environment. This feature allows users to accurately assess how their devices perform under different network conditions. For instance, the emulator introduces various impairments specifically tailored to V.90 ("56K") modems, V.34 modems, and V.34 fax machines, which can impact the highest achievable speeds. The TAS 1200D also emulates impairments commonly associated with accessing the internet through a local Internet Service Provider (ISP). Since most modem applications rely on ISP access via a local exchange, the emulator helps identify and address potential efficiency issues caused by transmission impairments in the local exchange.

The TAS 1200D comes equipped with multiple "network sections" that effectively model end-to-end networks, including a Private Branch Exchange (PBX) and/or Digital Loop Carrier (DLC) system connected to the PSTN. These tandem connections can significantly impact data transmission performance, and this emulator allows users to accurately replicate such scenarios in their testing environment. The emulator incorporates advanced Digital Signal Processing (DSP) techniques, ensuring unmatched precision and accuracy in its testing capabilities. While adhering to EIA/TIA and ITU standards, the TAS 1200D surpasses the minimum requirements to provide extensive test capabilities. By utilizing accurate and repeatable test conditions, the emulator enables early detection and elimination of equipment performance problems.

The TAS 1200D features a modular and field-proven architecture that can adapt to evolving test requirements. It seamlessly integrates with other TAS instruments and software, enabling users to create a comprehensive automatic test system. With its multiple digital interfaces (T1, E1, ISDN PRI & BRI, TDM bus), this emulator is specifically designed to test remote access service equipment and interface with digital network terminals. It accurately emulates local, transcontinental, and intercontinental connections, supporting both alpha and beta type mu-law PCM Codecs as required by TIA PN-3857. Additionally, the TAS 1200D meets and exceeds current and emerging EIA/TIA and ITU standards for telephone network emulation and modem testing. Its Universal Central Office functionality allows users to emulate virtually any local exchange or PBX format.
