The Series II Digital Telephone Network Emulator is the latest generation of the world's most advanced telephone network emulators. Series II Digital tests any type of device that communicates via the PSTN, including modems, remote access servers, fax machines, and other subscriber voice/data equipment.
- Provides a wealth of new transmission impairment conditions for V.90 ("56K"0 modems, V.34 modems, and V.34 fax. Many of these conditions, which occur on real networks, can prevent modems from operating at the highest speed.
- Emulates the impairments associated with local Internet Service Provider (ISP) access. ISP access through a local exhcange is currently the most popluar modem application, and transmission impairments in the local exchange can hamper the efficiency of these connections.
- Include several "network sections" to effectively model end-to-end networks that include a Private Branch Exchange (PBX) and/or Digital Loop Carrier (DLC) system in tandem with the PSTN. These tandem connections can have a significant negative effect on data transmission performance.
- Provides several digital interfaces for testing remote access server equipment and for interfacing to digital network terminals.
Features:
- Emulates local exhcange transmission impairments tha are essential for effective testing of V.90 ("56K") modems
- Emulates tandem PSTN/PBX/DLC connections for thorough testing of V.90 fallback, V.34 fax, and V.34 modems.
- Provides several digital interfaces (T1, E1, ISDN PRI & BRI, TDM bus) for testing remote access sever equipment.
- Effectively emulates local, transcontiental, and intercontiental connections.
- Emulates both alpha and beta type mu-law PCM Codecs, as required by TIA PN-3857
- Meets and exceeds current and emerging EIA/TIA and ITU telephone network emulation and modem testing requirements.
- Universal Central Office emulates virtually any local exchange or PBX format.
- Advanced Digitial Signal processing (DSP) architecture provides unprecedented accuracy, repeatability, and dynamic range.
- Field-proven modular architecture can adapt to evolving test requirements.
- Integrates easily with other TAS instruments and software to provide complete automatic test systems.
Options Included:
- Option DFE - Digital Facility Emulation module
