With the emergence and acceptance of open standards like AdvancedTCA, OEMs now have the option of leveraging Common-off-the-shelf (COTS) equipment to accelerate their time-to-market. However, to meet solution requirements, OEMs need the same level of sophistication and re-use that they are accustomed to in their own designs. They must confront the challenge of choosing a shelf that not only meets the carrier grade needs, but also is flexible for their common platform requirements.

Product Description
The Promentum ATCA-6000 is an ATCA shelf that provides the reliability, availability, serviceability and manageability (RASM) required for building diverse ATCA systems. Its true 12U height enables 3 shelves to fit comfortably into a standard frame while allowing room for other equipment as needed to realize a complete system. The shelf provides the platform infrastructure to host a multitude of AdvancedTCA modules – switch, CPU, line cards and storage modules, supporting applications ranging from Network Elements to Data Servers to High Performance Computing Platforms.

Common Carrier Grade Platform
The ATCA-6000 is designed and built for a central office environment. Redundancy is inherent in all design aspects, including power, cooling, control, and connectivity. Dual redundant –48V DC power is provided as required by the PICMG 3.0 specification.

Unique, RiCool-2 Function Provides 200W Cooling
The ATCA-6000 provides a sophisticated thermal solution to meet the diverse requirements of the OEM common platforms. The ATCA-6000 implements powerful blowers to execute “evacuation” based cooling functionality. The shelf manager also incorporates the heuristics based RiCool-2 function to control fan speed and handle various thermal faults. The system designer has control over configuring this software through the shelf manager.

Cooling is provided in an N+1 architecture, allowing continued operation with uniform airflow, regardless of any single fan failure. The shelf supports cooling for 200W per front slot with up to 30W of rear-transition-module cooling. All control subsystems are available in dual redundant configurations.

The ATCA-6000 provides standard telecom alarm I/O interfaces to be used in conjunction with other central office systems. The shelf is qualified for the central office environment via appropriate NEBS and ETSI certifications.

Flexibility
The ATCA-6000 shelf provides ample flexibility to allow initial system deployment with current technologies and in-field upgrades in the future. The backplane supports the full ATCA base and fabric interfaces in a dual-star configuration, with signal speeds up to 3.125 Gb/s. Thus, an initial deployment may utilize only the base interface and a subsequent upgrade may add modules supporting the fabric interface without the need to change the shelf or backplane. The shelf architecture enables OEMs to address multiple rack configurations – 19”, 23” and 535mm.

The backplane includes inter-slot update channels, synchronization clock buses, and metallic test & ringing signals.

Manageability
The ATCA-6000 implements a dual redundant IPMB bus for its out-of-band management functions. It supports both integrated (i.e., on a blade) and non-integrated (i.e., distinct module) shelf management, allowing the architectural choice to suit the application. Management of shelf peripherals (temperature sensors, etc.) is provided via a compact “shelf peripherals module” and exposed to shelf management via IPMI.

The ATCA-6000 also supports a display panel that facilitates local craft management via an LCD display and shelf-level LEDs.

The ATCA-6000 offers many more carrier grade friendly capabilities such as front and rear cable trays, air filters and minimum moving parts to provide mechanically sound design.

Overall, the ATCA-6000 is the perfect choice as a common shelf for products such as: IP Multimedia Systems (IMS), Media Gateway Controllers, HLR/VLR, SGSN/GGSN, RNC, BRAS and CMTS/DSLAM.
