Description

The ATLAS 830 Integrated Access Device (IAD) is a multi-function, modular platform that provides voice, data, video, and Internet connectivity, as well as 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/E1 bandwidth manager, ISDN PRI/BRI switch, Frame Relay switch, IP Router, NxT1 IMUX, and 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 24 E1/PRAs and offers a series of hot swappable option modules, allowing the system to satisfy many applications in either carrier or 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 E1 and T1 circuits in a small, 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 E1, 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 112 Kbps up to a full E1/PRA rate (1920 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. The ATLAS 830 offers a variety of serial interface options including V.35, EIA-232, EIA-530, RS-449, X.21, and V.36. It 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. It can also be optioned to transport up to 64 compressed voice connections over a Frame Relay network. The ATLAS 830 also 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 indication of operational status.
