Tormenta ISA Card, Rev. A -- Schematics and Board Artworks

Tormenta 2 PCI Card, Rev. B -- Schematics and Board Artworks

Click Here for Radio Repeater/Remote Base Interface and Application


Now Available!!

The Tormenta ISA PC card, supporting 2 full channelized-T1circuits (48 voice ports) is available in small quantity now. We are no longer building cards ourselves. There are, however, several entities that are making them currently. You can send us email (see below), and we will pass along your requests/orders to the entities currently manufacturing the boards.  For those wishing to fabricate their own cards, the gerber photoplot files may be downloaded here. (picture of baby food jar)
Please note Mandatory Engineering Change.

PCI Version Development Completed

10/22/01 -- After much pain and torment (this process has dragged out over months and months now), a PCI version of the card (supporting 4 T-1/E-1 interfaces) has been developed and tested along with a new version of the driver, supporting this hardware and more.

These cards are currently available from Linux Support Services in Alabama. They are now in full production, and the cards are readily available. For information on pricing and availability, please contact Mark Spencer (markster@linux-support.net). For those wishing to fabricate their own cards, the gerber photoplot files may be downloaded here. (picture of baby food jar).

The 'tor' driver source and header, and Zapata library source and header, and installation instructions are available now. The whole entire distribution (driver, library and browser application), including the Emiliano MIPL browser (which also serves as an excellent sample application) is available for download here.

In addition, the NEW LINUX version of the driver/library is now available for download, with MANY enhancements, including data modes, networking, and ability to use IDE hard drives.

We now have full E1/A-law support available in the LINUX drivers/library, plus ETSI (Euro, Net5) ISDN protocol is now supported in the PRI/PRA library.

(The "Asterisk" PBX is provided by Linux Support Services, Inc.)

The "Asterisk" PBX, an open-source PBX, based around the Linux operating system and the Tormenta card is now available. It has many features, including voice-over-IP/Frame-Relay capability, and Primary-Rate ISDN support (Both North American and Euro-ISDN). Check it out.


PC compatible system running FreeBSD version 3.X or 4.X (it should work on 2.X systems with little modification) or LINUX (with at least a 2.2 kernel), with at least a Pentium III, 700 Mhz processor (or equiv.), 64 MB 100Mhz Ram, Wide Ultra-II SCSI controller and drive (should also work with slower drives, but has not been tested) for FreeBSD or UDMA 66 IDE (ATA) for LINUX, and reasonable PCI network card (not a 3com for LINUX). The Tormenta ISA card must be the ONLY ISA card in the system, since it uses ALL the ISA bus bandwidth available.

Note: The NEW LINUX driver does not require SCSI disk hardware.


¡Viva la revolución de las computadoras telefónicas! ¡Viva Zapata!
