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.
