Sangoma Technologies Inc. announces availability
of alpha-version of Frame Relay implementation
for Linux operating system
Alpha version of Sangoma Frame Relay for Linux is now available to
all interested parties.
Frame Relay support for Linux is based on Sangoma's intelligent
multi-protocol Synchronous Data Link Adapters (SDLA) and implemented
as a set of kernel loadable modules allowing users to load drivers
as needed and unload them without re-booting their computers.
Drivers form two-level hierarchy:
o SDLA driver is responsible for controlling SDLA hardware and
provides foundation for upper-level protocol-specific drivers
such as Frame Relay, X.25, PPP, HDLC, SDLC, Bisync, etc.
o Frame Relay driver (called FLIP) integrates SDLA into Linux
TCP/IP protocol stack.
Both levels are fully dynamically configurable.
Following are key features of Sangoma Frame Relay implementation
for Linux:
o Support for up to eight SDLA cards. Different SDLA types can
be installed in one machine and supported by the same driver.
o Support for up to 24 DLCIs per card.
o SDLA driver automatically detects adapter type and performs
adapter autoconfiguration, where possible.
o SDLA driver allows to change hardware configuration dynamically,
without re-linking the kernel, re-booting PC or re-loading the
driver.
o Frame Relay driver can be dynamically bound to multiple SDLA
cards (Frame Relay ports). All Frame Relay ports are
independently configurable.
o Linux network interfaces can be created dynamically and assigned
to particular DLCI's on any Frame Relay port.
o Driver currently supports S502E SDLA card (64kbps or 128kbps versions.
It will soon support S508 card (T1/E1 speeds, more DLCIs)
- ------------
For users interested in the Linux driver package for the Sangoma S502E
card running Frame Relay, you can download the file LINUX_FR.ZIP from
the FTP area of our web site at www.sangoma.com.
We would welcome any comments on this driver set, as we would like to make
this packagethe best it can possibly be.
The Sangoma Linux drivers, unlike some of the other Linux drivers
written for Sangoma hardware, makes use of system interrupts. This
means that it will not run on the older S502A cards (long, 2 layer
cards). For those who have the long cards we are offering a limited
time exchange program to upgrade to the newer cards for $120.00 each.
Plese contact me if you are interested.
