Working with Advanced Mezzanine Card's? If so, check out Artesyn Communication Products (a subsidiary of Artesyn Technologies in Madison, Wis.) new hot-swappable AMC cards.
Artesyn now has what it says is the industry's first AMC.
The hot-swappable Pentium M-based AMC module, code-named the AM7501, gives telecom OEMs a way to add processing power to AdvancedTCA (Advanced Telecom Compute Architecture, or ATCA), or proprietary systems equipped with AMC expansion bays.
Artesyn says its AM7501 will work as a control plane processor for optical and wireless infrastructure uses, or for augmenting packet processing and routing in voice gateways.
It can also be used for enhancing protocol processing performance in SS7 and SIGTRAN signaling control points and gateways.
Moreover, the AM7501 complies with the draft AMC spec, and will comply fully with the final AMC specification upon ratification.
Not The First, But . . .
"AMC isn't the first mezzanine architecture to target the telecom industry," says Michael Franco, hardware engineering manager at Artesyn, and chair of several AMC working groups. "But it is the first to provide hot swappability and integrated system management.
"That enables individual AMC modules to be remotely monitored, controlled, and replaced in the field. This, along with AMC's high-bandwidth I/O interface, high-power handling capability, and versatile form-factor, makes it useful for building highly modular telecom systems that can be scaled, upgraded, serviced and provisioned with a high degree of granularity and minimal disruption to overall system operation."
The AM7501 is a single-wide, full-height AMC card that can be used with an ATCA or proprietary carrier card providing AMC bays.
Optimized for embedded control, AM7501 features a 1.6-GHz Pentium M processor with a 400-MHz, 3.2-Gbyte/sec Front Side Bus, one Mbyte of Level 2 cache, and SIMD extensions for compute-intensive applications like multimedia and packet processing.
Server-Class North Bridge
Franco notes that the AM7501 also features a server-class E7501 north bridge, which gives the Pentium processor high-speed access to local ECC SDRAM (up to 2 GBytes).
The north bridge also connects to a 64-bit PCI-X bridge, which provides high-speed access to two Gigabit Ethernet channels, up to 128 Mbytes of flash, a Universal Serial Bus interface, an I2C system management interface, and a front panel 10/100BaseT management interface.
Gbit Ethernet Communications
The AM7501 communicates with ATCA carrier cards via its two Gigabit Ethernet channels, which are routed to the module's AMC connector.
Also routed to the AMC connector is the module's I2C-based Intelligent Platform Management Interface (IPMI), which enables it to be monitored and controlled through the ATCA carrier card by remote shelf management controllers.
The AM7501 also provides an optional on-board storage interface, which gives it access (through the AMC connector) to hard drives that may reside in other AMC bays on the ATCA carrier.
ATCA is a standard (PICMG 3.0) platform spec defined by the PCI Industrial Computer Manufacturers Group (PICMG)for a telecom shelf. The spec defines the mechanical and electrical interfaces for the ATCA card cage (or shelf), as well as the ATCA cards (blades) that plug into that shelf.
Key ATCA features include a high-bandwidth switched fabric interconnect, integrated system management, hot swappability, higher power handling capability (up to 200-W/blade), a large 8U form-factor, and multi-protocol support (Ethernet, Fibre Channel, InfiniBand, StarFabic, PCI Express, and RapidIO).
AMC (AdvancedMC) is a proposed PICMG specification (PICMG AMC.0) for hot-swappable, field-replaceable mezzanine cards. Optimized for packet-based, high-availability telecom systems, AMC cards can be attached to a variety of ATCA and proprietary carrier blades.
Packet-Based Serial I/O
In use, AMCs communicate with the carrier card via a packet-based serial interface, which features up to 21 lanes of high-speed I/O (12.5 Gbit/s each). AMC is slated to support a variety of protocols, including Ethernet, PCI Express, and Serial Rapid I/O. AMC also features integrated I2C-based and Ethernet-based system management.
Operating System Support
Operating system support for the AM7501 product includes Carrier Grade Linux.
The AM7501 is priced at $1500, in OEM quantities and will be available as part of Artesyn's early customer involvement program in the second quarter of 2004.
