Product Details
__
The HC5517 is a ringing SLIC designed to accommodate a wide variety of local loop applications. The various applications include, basic POTS lines with answering machines and fax capabilities, ISDN networks, wireless local loop, and hybrid fiber coax (HFC) terminals. The HC5517 provides a high degree of flexibility with open circuit tip to ring DC voltages, user defined ringing waveforms (sinusoidal to square wave), ring trip detection thresholds and loop current limits that can be tailored for many applications. Additional features of the HC5517 are complex impedance matching, pulse metering and transhybrid balance. The HC5517 is designed for use in systems where a separate ring generator is not economically feasible.
