Other Specification : LUCENT 5ESS UN376B 1:3 950C04520944 SPPQABE DISK FILE CONTROL UN Description: LUCENT LUCENT 5ESS UN376B DISK FILE CONTROL UN HEC:SPPQABEAAB SPPQABE Desc:5ESS DISK FILE CONTROL UN Lucent 5ESS Switches The Alcatel-Lucent 5ESS Switch Is A Class 5 Telephone Electronic Switching System (ESS)*. It Supports A Multitude Of Applications That Can Be Configured To Coexist With Each Other Thereby Allowing Operators To Implement Different Applications More Cost-effectively On Just One Switch Instead Of Multiple Switches. For Example, The Same 5ESS Switch Can Simultaneously Support Wireless, Local-Toll, Intelligent Network (IN), And Gateway Exchange Applications. Supporting Both Wireless And Wireline Operations, It Has High Reliability, Modular, And Standards-compliant Architecture.The Unique Architecture Of The 5ESS Switch Enables Modular Upgrades And Implementation Of Multiple Services On One Switch, Providing Strong Economies Of Scale In Training, Management, And Spares. As A Result, You Can Pursue Business And Network Strategies Without Locking Your Company Into A Specific Technology And Without Interrupting Current Services. 5ESS Has Three Main Kinds Of Module: AM Is Administrative Module, Which Contains The Central Computers. CM Is Communications Module, Which Is The Central Time-divided Switch Of The System. SM Is Switching Module Which In Most Exchanges Is The Majority Of Equipment. SM Performs Multiplexing, Analog/digital Coding, And Other Work To Interface With The Outside World. Each Has A Controller, A Small Computer Whose CPUs And Memories, Like Most Common Equipment Of The Exchange, Are Duplicated For Redundancy. Distributed System Lessens The Load On The Central Administrative Module (AM) Or Main Computer. Power For All Circuitry Is Distributed As 48VDC (nominal) And Converted To Logic Or Telephone Voltages As Needed By DC To DC Converters
