A modular electrical circuit that connects to a telecommunications network is a SLIC, sometimes referred to as a subscriber line interface card. Both the conversion of analogue voice communications to digital and the reverse are done using it.
A transient output current limit circuit and two output amplifiers connected to the subscriber loop make up a subscriber line interface circuit (SLIC).
The Global Subscriber Line Interface market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The HC-5502X/4X Telephone Subscriber Line Interface Circuits (SLIC). The HC-5502X/4X family of telephone subscriber lines\interface circuits (SLIC) integrate most of the BORSCHT\sfunctions of the traditional hybrid transformer interface circuits\sonto one chip.
The circuits provide 1kV of isolation from lightning-induced faults between the subscriber loop and the telephone office and are produced using a 200V dielectric isolation (DI) method. This isolation is combined with a secondary protection diode bridge.
Although they can be utilised in the bigger switch networks found in Central Offices, the HC-5502X/4X series of SLICs is primarily designed for usage in Private Branch Exchanges (PBX) (CO).
The short loop current is limited to 30mA by the HC-5502X for single ended tip (positive side) injected ringing systems and to 40mA by the HC-5504X for ring side (negative side) injected ringing systems.
The HC5504X can also be set up to work in switches using either of the two single ended ringing methods and in balanced ringing systems, it should be noted.
