What is the purpose of the device?
ATM Network card (http://en.wikipedia.org/wiki/Asynchronous_Transfer_Mode)
ForeRunner PCA-200E is a 32-bit, 155 Mbps PCI-based adapter familiy includings boards supporting multimode (both ST and SC connector) and single mode fiber as well ass UTP 5 cabling with RJ 45 connector. Features include: * support of UNI 3.0, UNI 3.1, LANE 1.0, RFC 1577 and ILMI. * On board 25 MHz i960 cell processor * Enhanced SAR Processor (ESP) ASIC * Special-purpose hardware for AAL5 and AAL3/4, HEC, and CRC calculations * Supports Available Bit Rate (ABR) with ForeThought software * ATM cell processing per ANSI T1S1.5/92-002R3, ITU I.361, ATM Forum UNI v3.0 specification
Who needs it?
(which computer models use this device or which niche users usually buy such peripherals?)
How critical it is to get free support for it?
(Is it a very popular device that requires us to prioritize efforts?)
What is(are) the processor architecture(s) of this device?
- on-board 25MHz i960 Intel RISC processor
The PCA 200E cards have a good level of signalling performance because they have an on-board 25MHz i960 Intel RISC processor performing cell processing using buffer rings in the same manner as an Ethernet controller.
Who is working on a free firmware implementation?
Links to online documentation
(i.e. datasheets, developer's guides, official or non-official specifications, etc)
Where are the non-free firmware images made available?
- http://os.inf.tu-dresden.de/pca200e/pca200e.bin (old firmware version)
What makes them non-free?
Source code is not available.
What else do we know about this device?
(any further info that might help the creation of free firmware for it)
Following are the features of the PCA 200E cards: * 155 MHz ATM, ST/SC SM/MM and RJ-45 UTP 5 * AAL1, AAL2, AAL3 and AAL5 modes. * Integrated 25 MHz i960 RISC cell processor. * Enhance SAR Processor (ESP) ASIC * Special-purpose hardware for AAL5 and AAL3/4, HEC, and CRC calculations. * Dual-ported RAM and Buffer Ring technique similar to Ethernet Controller. * Serial communications emulation. * Supports ABR * ATM cell processing per ANSI T1S1.5/92-002R3, ITU I.361, ATM Form UNI v3.0, 3.1, 4.0 Advantages Following are the advantages of the PCA 200E cards: * Inexpensive (about $200 a card). * Supports MTP3b. * Can support 3GPP UMTS Iu User and Control Plane over PVCs. Disadvantages Following are the disadvantages of the PCA 200E cards: * Does not support traditional SS7 links. * Requires external ATM switch or point-to-point ATM connection.
