描述 Description

Overview MS140131KT removed from active portfolio. Possible Replacement Part: none.
The MS140131KT chipset provides all the functions necessary to connect analog telephone sets or other analog terminals (telefax, answering machines, modems, etc.) into digital communication systems. It provides an economical solution for the traditional BORS(C)HT (Battery, Overvoltage, Ringing, Supervision, (Codec), Hybrid, Test) functions found in central-office exchanges, but is optimized for short-range communication (e.g., up to 500 m with four RENs (Ringer Equivalence Number) attached). Virtually all system-dependent parameters can be set under software control, giving an unprecedented flexibility to the system integrator, as well as optimizing the system cost. The digital interface to the SH-POTS (Short Haul, Plain Old Telephone System) chipset uses the industry-standard GCI interface. The system architecture has been designed to offer the most cost-effective solution for short-haul systems, yet offers the full flexibility required to meet worldwide analog telephony standards. The MS140131KT chipset is also suitable for Q.552 applications.
The MS140131KT chipset comprises three devices: a pair of high-voltage devices, the Short-Haul Line Interface Circuit (SHLIC) which provides the signal and power interface to the analog lines (one per line) and a low-voltage CMOS, DSP-based dual codec/control device (CODSP) which provides all signal processing and control functions for up to two lines.
