Acting like a central office switch, the ATLAS 830 and ATLAS 550 can emulate Frame Relay, ISDN and analog circuits. Network engineers, design and test engineers and classroom instructors can easily stage real-world circuits and "what if" scenarios, test new technologies, or configure equipment without purchasing live circuits or incurring toll charges from a carrier. For Frame Relay WAN emulation, both fully meshed and hub-and-spoke networks can be configured using the RFC 1490 protocol. As an ISDN switch, the ATLAS can emulate both BRI and PRI dial-up networks. Both BRI and PRI support multiple switch types like the DMS 100, Lucent 5E and National ISDN, with additional support for the Lucent 4E switch with PRI. EuroISDN switch protocol is also supported for E1/PRA, BRI ‘S/T’ and BRI ‘U’ interfaces. Supporting analog FXS circuits, the ATLAS 550 can configure 1–32 loop start lines. An FXS module for the ATLAS 830 is not currently available, but scheduled for future development.
Integrated Access Device The ATLAS™ 830 Integrated Access Device (IAD) is a multi-function, modular platform that provides voice, data, video, and Internet connectivity and WAN access to reduce overall telecommunication expenses. The ATLAS 830 is designed to be installed between the network service provider’s circuit(s) and customer premises equipment enabling many network devices to share WAN access and bandwidth. This flexible and modular platform functions as a T1/T3/E1 bandwidth manager, ISDN PRI/BRI switch, Frame Relay switch, IP Router, NxT1 IMUX, and 3/1/0 DACS. It also includes intelligent call routing through the integral switchboard and dial plan that provides dynamic call-by-call switching based upon the called or calling phone number. The ATLAS 830 is an eight slot, modular platform that supports up to 34 T1/PRIs or 32 E1s and offers a series of hot-swappable option modules, allowing the system to satisfy many applications in corporate networks. The ATLAS 830 chassis includes two independent software programmable network interfaces that can be configured for T1, DSX-1, or PRI operation. The ATLAS 830 provides DACSing and grooming for T3 and T1 circuits in a small and economical footprint. Users can perform time slot interchange and reassign or crossconnect any DS0 from any circuit to any other circuit. The ATLAS 830 also provides dynamic circuit switching on the high speed backplane. ISDN and voice switching are performed on a call-by-call basis for on-premises routing or least cost routing to the public network. The ATLAS 830 supports video applications by providing multiple T1, PRI, BRI, V.35, RS-449, EIA-530 and RS-366 interfaces for codecs and gateways. By using the Nx56/64 BONDing module, video calls ranging from 112Kbps up to a full PRI rate (1.472 Kbps) can be supported. For data applications, users can connect the ATLAS 830 directly to the LAN using the integral 10/100BaseT Ethernet interface and internal IP routing software. Users can also connect an external router or other device through one or more serial ports. ATLAS 830 offers a variety of serial interface options, including V.35, EIA-232, EIA-530, RS-449, X.21, and V.36. The ATLAS 830 includes Frame Relay software as well as an IP router and support for PPP applications. Voice over Frame Relay (VoFR) is supported using one or more of the optional Voice Compression Modules to deliver high quality voice among Frame Relay sites. The ATLAS 830 can be configured to transport voice and data traffic within a single PVC, reducing monthly expenses. An ATLAS 830 can be optioned to transport up to 64 compressed voice connections over a Frame Relay network. ATLAS 830 supports IP routing over public and private Frame Relay networks. For network management, the ATLAS 830 supports N-Form® and offers local and remote management capabilities using Telnet or VT100 connected to the built-in 10/100BaseT Ethernet interface. The ATLAS 830 also includes LEDs for complete operational status indications.
