SDL's Gateway Products for Unix Internet Servers Complete Internetworking Product Line SDL's RISCom/N2 product line allows you to save time and money by combining three products into one. The RISCom/N2csu and RISCom/N2dds combine a communications card, CSU/DSU and a Router into one cost effective, easy to install card. With SDL's RISCom products, you can have a fully integrated Web Server, Internet Gateway or Router in one machine. SDL's RISCom/N2 family offers significant savings and expandability over costly external Router and CSU/DSU solutions. SDL offers a range of Internet products using Unix based Internet Servers on the Intel x86 and Pentium processors, supporting ISA, EISA and PCI buses. The RISCom boards are offered with a variety of interfaces including RS232, RS422, V.35 and X.21. There is a RISCom board for virtually all of your PC internetworking requirements, whether your application be Synchronous for Internet routing, or Asynchronous for modem dial-up. RISCom/N2 & RISCom/N2pci The RISCom/N2 is a low-cost, high performance dual port Multiprotocol Adapter for the ISA and PCI bus. Combined with Unix Internet Servers, the RISCom/N2 becomes a cost effective Internet/ WWW Gateway/ Router running at 56K, full and fractional T1/E1, replacing costly external routers. FEATURES Cisco HDLC and Sync PPP compatible. Two Full Duplex DMA Ports T1, Fractional T1, 56K dds 64KB of Dual Port RAM RS232, EIA530, X.21 or V.35 Seamless Integration with Unix systems.

APPLICATIONS Internet/WWW Router/Server X.25/SNA Gateway/Server Frame Relay Access PORT 1: T1 or 56k CSU/DSU Alarms include Yellow, Red, Blue, Loss of Signal, Bipolar Violations, Loss of Framing Master or Slave clocking RJ48C connector Compliance with ANSI T1.403, AT&T PUB 54016 and 62411, FCC Part 15 (Class A) & Part 68 & IC CS-03 RISCom/8A The RISCom/8A is a Low Cost, High Performance RISC Technology based Multi-protocol Adapter for the ISA Bus offering 4 or 8 Async ports. The RISCom/8A features a modular daughter card physical interface design available with RS232, EIA530 and custom interfaces. Installed in a Unix system, this board allows you to control up to 8 high-speed (to 115kbps) modems. FEATURES 4 or 8 Full Duplex DMA Async Ports 64/256KB of Dual Port RAM Data Buffers Async operation to 115.2 Kbps Low Power CMOS RISC Technology PC INTERFACE 16 bit ISA Bus I/O Address Selectable from 100-3FF Hex Jumper Selectable IRQ 3, 4, 5, 7, 10, 11, 12, 15 Interrupt Sharing Supported Shared RAM: 64KB Programmable Base Address Programmable Window Size (8K, 16K, 32K or 64K Bytes) 16 Megabyte ISA memory range COMMUNICATION CONTROLLER 4/8 Ports One or Two 32Mhz CL-CD2401 Controllers Async, Async PPP Full Duplex DMA on all ports with Byte or Word Transfers SERIAL INTERFACE MODULES RS232, RS422, EIA530 Modem Signals: RTS, CTS, DTR, DSR, DCD, TXCI, RXCI, ETCO TXCI, RXCI, ETCO Clock support 110 - 128K Baud support DB37, DB62, HD100, Cabling: Octal Adapter Frame Relay Software The Frame Relay Protocol is a link layer Protocol that enables the SDL RISCom/N2 family of WAN adapters to communicate using IP Datagrams with remote hosts over a Frame Relay Network. The product provides the Frame Relay DTE functionality of supporting multiple DLCIs and protocol multiplexing over individual PVCs. It supports Inverse ARP (Address Resolutions Protocol) per RFC-1293 to resolve IP addresses associated with particular DLCIs. Using a static routing table, the product is configurable to perform the task of a Network Gateway.
