MCU - Management and Concentration Unit

MCU - Management and Concentration Unit

Product Overview

MCU

The Management and Concentrator Unit (MCU) acts as a management interface card capable to control up to 64 plug-in units in up to 4 cascaded subracks. Management information of other MCUs can be aggregated using MCU’s Ethernet switch.
Network operators connect to the MCU using either ULAF+’s, Local Craft Terminal software or Albis’ network management system «AccessIntegrator» to access the MCU’s inventory, alarming and maintenance, configuration, performance and security features.


MCU-S

The MCU-S integrates additional to the MCU functionality a carrier grade Ethernet switch to aggregate Ethernet traffic of up to 16 line cards. The switch features 16 internal Ethernet tributary ports for line card traffic and two Gigabit Ethernet uplinks.


MCU-CES

The MCU-CES includes all the features of the MCU-S plus the Circuit Emulation Service (CES) functionality. The MCU-CES is designed to run E1 voice and data services emulation over packet switched networks. Together with the ULAF+ transmission units the MCU-CES module optimizes performance and cost efficiency of metro Ethernet applications.
