Tahoe 971/972 - WAN PCI Cards with G.703 Interface
Tahoe 971 and Tahoe 972 cards are equipped with, respectively, one
or two G.703 interfaces capable of transferring data
at speeds up to 2048 kbps each.
Each G.703 port may work in unframed or framed mode. In the latter data
may be transmitted over any combination of timeslots with throughputs
ranging from 64 to 1984 kb/s. In the unframed mode transparent 2048 kbps channel is
available.
Built-in hardware HDLC controller fully takes care of the serial
communication without any significant load added to the server's CPU.
Linux and FreeBSD drivers are available, supporting Frame
relay, synchronous PPP and HDLC. CD-ROM delivered with the card contains
current drivers, Linux kernel sources (unmodified and with patches applied) and
user manuals for all Tahoe products.
