FarSync WAN X.21 / V.35 universal PCI / PCI-X intelligent cards
provide versatile high performance synchronous connectivity to the
Internet, satellite connections or to corporate networks over leased
lines.
The versatile intelligent FarSync WAN T-Series cards provide up to
10 Mbits/s per port WAN solutions for your
X.21,
V.35 and RS530 connectivity requirements. Whether you are
connecting to the Internet, satellite links, private networks using TCP/IP
or connecting sites using leased lines, FarSync cards provide the
connectivity solution, replacing standalone routers and firewalls.
The cards install seamlessly under Linux kernel series 2.2, 2.4 and
now 2.6 on both single and multiprocessor systems. The drivers are
included as standard in the kernel. Distributions by Redhat, SuSE,
Slackware, Mandrake, Debian, Pink Tie and United Linux are supported.
The link level protocol can be PPP, Cisco HDLC or Frame Relay.
Each serial port provides a standard point-to-point network interface
controllable with all the standard Linux networking tools.
Multiple cards can be installed to create a very low cost high speed
Wide Area Network (WAN) hub.
E1, fractional E1 (G.703 and G.704) types of connection are
supported using the
FarSync
WAN TE1 - E1 card and also
interface
converters.
The FarSync WAN T-Series X21 / V35 adapters are suitable for connection
to TCP/IP networks and HDLC lines. Typical applications include:
- High speed Internet access
- Frame Relay Internet access
- Remote office access over leased lines
- PC-based multi-port wide area network hub (Routers and Firewalls)
- Satellite multicasting
- Video conferencing
The T-Series intelligent adapters have been designed for high
performance and flexibility. The cards are driven by 50 MHz AMD Am186
CC/CH processors with 1 Mbyte of on board zero wait state SRAM memory
mapped to the PC. The PCI Bus mastering DMA interface on the FarSync T1U,
T2U and T4U provides a very high performance interface to the card whilst
minimising PCI and PC CPU loads.
- Synchronous l ine speeds up to 10 Mbits/s
- X.21
(V.11 / RS422), V.35, RS530 (EIA530),
RS232C
(V.24 / X.21bis) and RS449 (using conversion cables)
- 1, 2 and 4 port cards
- PCI Bus mastering DMA interface on the FarSync T1U, T2U and T4U
A wide range of PCI bus specifications can be catered for using the
cards in the FarSync T-Series range. The guidelines below should help you
decide which card is right for your system.
Single processor PCs with a basic 32 bit PCI bus
The FarSync T1U, T2U
and T4U cards are also suitable for single processor PCs with a
basic 32 bit PCI bus as long the PCI bus is PCI revision 2.1 (or
greater) compliant. With the introduction of PCI revision 2.1 it became
mandatory to provide a 3.3 volt power supply to the PCI bus. The T1U,
T2U and T4U cards take their power from this 3.3 volt supply. The PCI
2.1 standard was introduced in 1995 so most PCs produced since that date
will be compliant. Suitable PCs will also be fitted with an ATX type
power supply which provides a 3.3 volt supply to the mainboard.
Single processor systems with a PCI-X bus or Multiprocessor
systems
The FarSync T1U, T2U and T4U cards are suitable for single
processor systems with a PCI-X bus and all Multiprocessor systems. These
cards are PCI revision 2.2 compliant and support both 3.3 and 5 volt
signaling, with the power for the adapter derived from the 3.3 volt
supply rail. The FarSync T1U, T2U and T4U cards may be fitted in either
32-bit PCI bus slots or 64-bit PCI-X bus slots as these are Universal
PCI cards and will work perfectly well in both.
Systems featuring Intel processors with HyperThreading
The FarSync T1U, T2U and T4U cards are suitable for systems
with Intel processors featuring HyperThreading technology, including
Pentium 4, Xeon and Xeon-MP CPUs. These cards are PCI revision 2.2
compliant and support both 3.3 and 5 volt signaling, with the power for
the adapter derived from the 3.3 volt supply rail. The FarSync T1U, T2U
and T4U cards may be fitted in either 32-bit PCI bus slots or 64-bit
PCI-X bus slots as these are Universal PCI cards and will work perfectly
well in both. Note: HyperThreading was introduced in the Xeon-MP in
March 2002 it appeared on other more mainstream Intel processors in
early 2003.
In general, unless the card is required to be fitted in a particularly
old PC or possibly certain Military or industrial PCs which have just a 5
volt power supply to the mainboard, then we recommend using the FarSync
T1U, T2U and T4U cards. If you are not sure about your particular system,
contact us and we can provide advice on the card that is most suitable for
your System.
A large number of ports can be supported by the installation of
multiple FarSync cards in a PC. The T1U, T2U, and T4U adapters
can be intermixed. In a typical mini tower PC 4 cards can be supported
providing up to 16 ports, rack mounted Servers can support 12 or more
cards (48+ ports) utilising more than one PCI bus; the card limit is
only dependent on the resources available in the host PC.
Where an API is required to HDLC or transparent bit stream formats the
FarSync
OEM range of cards should be used.
A simple installation procedure will make the device driver available
via the standard kernel configuration mechanism. The driver may be either
permanently linked to the kernel or used as a dynamically loadable
module.
A configuration tool is provided to set line speed, interface and the
protocol, after which the ports may be configured with standard networking
tools. Examples and default configurations are provided with the on-line
documentation.
For kernel versions 2.2.21 and 2.4.9 and above the drivers are included
as standard.
A daemon is included that allows the signals on any or all ports to be
automatically monitored. The network interface associated with a
specific port can then be brought up or down to reflect the line
state. This allows routing tables to be dynamically recalculated to
reflect destinations actually available.
The cable and connector configurations for each card type are described
here. The
FarSync
WAN T-Series product range table lists the cables available for each
card type. Crossover cables, sometimes referred to as null modem
cables, are also listed.
FarSync WAN T1U and FarSync WAN T2U
These one and two port cards have separate high-density D type
connector for each port on the card. Cables supporting
X.21
(V.11 / RS422), V.35, RS530 (EIA530), and
RS232C
(V.24 / X.21bis) are available plus RS449 via X.21 conversion cables.
FarSync WAN T4U and FarSync WAN T4P
These four port cards uses a single large high-density D type
connector on the card with all four lines available though this
connector. The quad port cables splits out the four network interfaces
into separate network connectors. Cables supporting
X.21
(V.11 / RS422), V.35, RS530 (EIA530), and
RS232C
(V.24 / X.21bis) are available plus RS449 via X.21 conversion cables.
The product includes the communications card, driver software (with
source), utilities and documentation supplied on CD-ROM.
