This multi-T1/PRI enterprise platform converges voice, data, video, and Internet traffic through dynamic bandwidth allocation, T1 Inverse Multiplexing, circuit switching, and packet routing. The ATLAS 550 is designed for the small-to-medium networks with one to 18 T1/PRI ports, while the ATLAS 830 is designed for medium-to-large networks that require up to 34 T1/PRI ports or a T3. The ATLAS 890 supports up to 64 T1/PRI ports or a T3 and can be used in networks that require full system redundancy.
ATLAS Applications Include:
High-speed, multi-function backplane ATLAS is a modular and scalable platform the single piece of access equipment you need to select the most cost-effective options to meet current needs, while accommodating future growth. To take advantage of new service opportunities, or to meet new user requirements, simply add the appropriate option modules. Numerous interface options The configuration of an ATLAS system can vary widely depending on a number of factors. What applications are being accommodated? How much capacity do you need for each? How much excess capacity should be allowed for near-term growth? A large offering of network and device interfaces allows you to tailor an ATLAS solution to fit your current needs with the least possible expenditure, and still accommodate change. Pre-configured systems are available for popular applications.
Available interface modules include: • T1/PRI– • T3 with Drop & Insert– Channelized T3 connectivity with Drop/Insert to any other channelized T3 device • ISDN BRI/U– ANSI T1.601-compliant BRI U-interfaces to emulate or terminate ISDN from common switch types • ISDN BRI S/T– Multiple BRI S/T interfaces supporting Net-3 Euro-ISDN • Analog Voice– Options for FXS, FXO, E&M with popular call features; mapped or dynamically switched DS0s • Voice Compression– 4-, 8-, 16-, 24-, and 32-channel G.723.1 compression with a 6:1 ratio on analog calls from channelized T1,RI, or PRI; 32-channel ADPCM available • Nx56/64 V.35– Multiple synchronous V.35 ports support Nx56/64 Kbps operation up to 2.048 Mbps • Ethernet Switch (ATLAS 550 only)– Layer 2 switch with eight 10/100BaseT Ethernet interfaces • USSI– Multiple synchronous Universal Synchronous Serial Interface ports supporting EIA-530, RS-449/V.36, X.21/V.11, or EIA-232; Nx56/64 Kbps operation up to 2.048 Mbps • Legacy Data (ATLAS 550 only)– Multiple EIA-232 or V.35 interfaces for synchronous or asynchronous packet data transport using SNA/SDLC, HDLC, transparent Async, and Transparent Bit-Oriented Protocols (TBOP) • NxT1 HSSI/V.35– Aggregates from two to eight T1s into a single logical channelin point-to-point applications; Supports multiple T1s or T3 • Nx56/64 Bonding– Two bonding Mode 1 processors with up to 2.048 Mbps capacity; from two to 32 user-configurable B-Channels per processor • Dual Video– Dual independent video ports simultaneously support different video module cables; includes RS-366 dialing interface and supports DTE rates from 112K to 1.472 Mbps (with additional card)
