Expansion Bank Control (EBC-3)
The EBC-3 card resides in the CPU slot(s) in the CBA expansion shelf, providing the interface to the system for all cards in the expansion shelf. The EBC-3 card manages the expansion shelf’s ATM, Ethernet and TDM backplanes, distributes system commands, and monitors the performance of each installed card. Use two EBC-3 cards in the expansion shelf for redundancy. The EBC-3 accesses the ATM cell bus on the expansion shelf backplane to enable broadband services. An expansion shelf is considered broadband-ready when it houses an EBC-3 card connected to an ELU-3 card located in the primary shelf.

Features and Benefits

  • Enables simple system expansion and control for expansion shelves
  • Supports transport of ATM, Ethernet and TDM traffic between shelves
  • Interfaces to an ELU-3 plug-in card in a primary shelf
  • Generates status updates to the CPU via the ELU plug-in card
  • CRC protection on the expansion link
  • Dual memory support for non-service affecting programming
  • Receives DDS timing from the primary shelf
  • Ability to derive timing reference from expansion shelf and transport it to primary shelf via the ELU plug-in card

Included Highlights

Scalability

Grow the Tellabs Multi-Service Access Platform with multiple expansion shelves over time while supporting ATM, Ethernet and TDM connectivity. The primary shelf can support up to seven broadband expansion shelves.

High Reliability

Install a minimum of one EBC-3 and ELU-3 cards plug-in card in the expansion shelf and primary shelf . For redundancy, install an additional EBC-3 and ELU-3 cards for high network availability configurations.

Fiber Connectivity

The EBC-3 and ELU-3 cards link via a fiber-optic connection. The expansion bank fibers (EBFs) transport the TDM and ATM data on separate multimode plastic fiber pairs that terminate directly to the EBC-3 and ELU-3 cards. The EBF fiber connection carrying ATM traffic between the ELU-3 and the EBC-3 operates at 155 Mbps to ensure full, non-blocking access to the transmission facility regardless of the plug-in card types used in the expansion shelf.
