FEATURES
• Connect 8 or 24 async V.35 devices to
any of three X.25 or Frame Relay links.
• V.35 main links have a top aggregate
data rate of 2.15 Mbps.
• Async channels can be set for data rates
up to 115.2 kbps.
• Supports async, X.25, Frame Relay,
HDLC, SDLC, STM, and SLIP.
• Built-in management agent for configuration, monitoring, diagnostics, statistics,
and reports.
The Fradswitch can be the centerpiece of just about any packet-switched network.
OVERVIEW
Do you have X.25 or Frame Relay service? Would you like
to hook up a set of V.35 async equipment to one, two, or
three synchronous Frame Relay/X.25 wide-area links and
switch between them all?
That’s exactly what the V.35 Fradswitch Asynchronous
(Fradswitch A) is designed to do. It’s a high-performance
switch that you can use for routing between async devices
and X.25 or Frame Relay connections.
V.35 Fradswitch A models have three synchronous mainlink ports, and 8 or 24 V.35 equipment link ports, proprietarily
pinned out on RJ-45 connectors.
The main-link ports can be set to use any of several
protocols: Besides the standard ones for X.25 and Frame Relay,
the Fradswitch also supports HDLC and SDLC, the proprietary
stat-mux protocol STM (for use with our Stat-8 mux), plain
async, and SLIP/encapsulated IP.
If you configure these ports for async or IP/SLIP operation,
their maximum data rate is 115.2 kbps for each port. (This is
also the top rate for each async channel.) If you configure the
main-link ports to use a sync protocol, they have an aggregate
data rate of 2.15 Mbps; that is, the total of the three ports’
data rates, added together, can’t exceed 2.15 Mbps.
The V.35 Fradswitch A has a powerful terminal-based
menu system that enables you to configure it for many types
of packet-switching applications, then operate it with little or
no maintenance. The unit supports permanent virtual circuits
(PVCs) and switched virtual circuits (SVCs), call IDs, NUI
databases, aliasing, IP routing and routing tables, Frame Relay
funneling, X.32 (XID) tables, SNMP management and event
reporting, X.25 multicasting—and much, much more!
Multisession is also provided on each async channel; each
channel can access up to four separate sessions simultaneously. This Fradswitch feature makes it easy for you to
compare data from different sources.
The V.35 Fradswitch A is rackmountable, and it also has
flash memory, so you can keep upgrading it—with even more
features—for as long as we keep releasing new firmware
revisions.
