A 2003 recount gave the city a population of 2,293. , one of the nation's largest competitive access providers of voice, data, and video communications services for major metropolitan business centers throughout the U.S., has been a long-time user of TyLink's stand-alone ONS ONS Office for National Statistics (UK) ONS One Night Stand ONS Onslaught (Unreal Tournament 2004) ONS Oncology Nursing Society ONS Object Naming Service ONS Offshore Northern Seas 150 and ONS 400 DSU/CSUs for reliable access to Fractional T1 services. MFS Telecom recently tested the TyLink 7400 WAN Champion for use in a major network expansion to reach 75 metropolitan areas over the next three to five years. According to Dan Montgomery, Jr., director of client network engineering at MFS Telecom, "We've been using TyLink's products for a while now and have been pleased with their reliability, ease-of-use, and support. With our network expansion, multiple circuits will come into each metropolitan node. We therefore need a rack-mounted solution that conserves space and provides high reliability features. We rigorously tested the 7400 WAN Champion and look forward to deploying it nationwide." Tri-Bus Architecture The 7400 WAN Champion is a modular, chassis-based platform with 16 slots for various communications modules; power supplies; and a mid-plane segmented into three independent buses. o Management Bus -- This bus is a 64 Kbps channel designed for management and control of the entire 7400 WAN Champion. It can be accessed locally or remotely via in-band or out-of-band supervisory channels. A separate controller is not required as any module in the chassis is capable of managing the Management Bus and all other modules. Information can be passed on to an external manager and controlled using TyLink's TyView/PC(TM), TyView/SNMP(TM), or TyView/SNMP for OpenView management applications. o Multiplexer Bus -- The Multiplexer Bus enables module-to-module data and signaling transfer and allows a number of low-speed ports to be multiplexed together for transmission over a single high-speed port. It also allows for digital cross-connects between a number of ports. The Multiplexer Bus is comprised of 16 individual high-speed channels, each of which can operate up to 8 Mbps. A failure on any single channel will not have an adverse affect on the other channels. o Cell Bus -- The Cell Bus is designed to accommodate easy migration from low-speed digital services to ATM. High-speed ATM modules operating at T3 (44.836 Mbps) to OC-3c (155 Mbps) can communicate with lower speed modules via the Cell Bus. Low-speed, non-ATM traffic can be aggregated for transmission over ATM to either a locally attached ATM switch or to an ATM carrier-based service. o Communications Modules -- These modules connect to the mid-plane from the front of the chassis. Modules support multiplexing, ATM, Frame Relay, and switching devices. Network interfaces include T1, E1, ISDN PRI, 56 Kbps DDS, T3, and OC-3c (ATM). o I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output Modules -- Physical connections are provided via interface modules inserted into the rear of the chassis. These connections include both network connections to carrier services as well as DTE (Data Terminating Equipment) A communications device that is the source or destination of signals on a network. It is typically a terminal or computer. Contrast with DCE.  DTE - Data Terminal Equipment (data terminal equipment) interfaces including V.35, RS-449, and EIA-530 for the attachment of equipment such as multiprotocol routers, synchronous data equipment, and videoconferencing equipment. Smooth Migration to ATM The TyLink 7400 WAN Champion has been designed with migration flexibility in mind. It can operate as a basic, central site multiplexer chassis for density purposes as well as meet the needs of more advanced applications such as ATM. In addition to supporting private dedicated line networks, the 7400 WAN Champion has been architected to support newer, switched-based networks such as ISDN and ATM. This allows for a managed migration to future technologies while protecting the investment in legacy systems. High Availability Features The 7400 WAN Champion includes a number of high availability features. The dual and loadsharing power supplies are individually fused, protecting against a single fuse failure bringing down the entire unit. Independent power switches and two power cords protect against accidental shutdown of the chassis and ensure constant power from separate sources. A power failure alarm is included as a standard feature. All communications modules are hot swappable. The active modules are inserted from the front, eliminating the need to re-attach cables or use tools prior to removing modules. Rear-inserted DTE interface modules are passive to ensure a very high mean-time between failures (MTBF (Mean Time Between Failure) The average time a component works without failure. It is the number of failures divided by the hours under observation. MTBF - Mean Time Between Failures ). Flexible Network Management TyLink's TyView/PC, TyView/SNMP, and TyView/SNMP for OpenView network management systems provide complete control of large geographically dispersed networks from a central site. TyView/PC, which runs on any IBM-compatible PC, allows users to configure, control, and monitor TyLink's dedicated access products. Advanced features include real-time reporting and user-friendly diagnostics for problem isolation, password protection, help screens, and pop-up menus. Incorporating all TyView/PC features, TyView/SNMP provides centralized network management through SNMP to configure, control, and monitor TyLink's access products. TyLink supports a full range of SNMP GETs, SETs, and TRAPs; private MIB (1) (Management Information Base) The hierarchical database used by the simple network management protocol (SNMP) to describe the particular device being monitored. MIB objects are identified using ASN.1 syntax. See SNMP, RMON, OID and ASN.1. extensions are available to access all capabilities possible from the unit itself. Because TyView/SNMP can be used in conjunction with any SNMP-based management system, users can monitor and control WAN equipment with the same management system already in place for their LANs. TyView/SNMP provides a gateway into other management platforms including HP OpenView, SunConnect's SunNet Manager, IBM (International Business Machines Corporation, Armonk, NY, www.ibm.com) The world's largest computer company. IBM's product lines include the S/390 mainframes (zSeries), AS/400 midrange business systems (iSeries), RS/6000 workstations and servers (pSeries), Intel-based servers (xSeries) NetView for AIX (Advanced Interactive eXecutive) IBM's Unix-based operating system which runs on its Intellistation workstations and pSeries, p5, iSeries and i5 server families. , and Cabletron Spectrum and LanView. Pricing and Availability In order to offer customers the flexibility they need at a desirable price point, TyLink is offering two chassis versions of the 7400 WAN Champion. A two-bus chassis with one power supply is available now for $1,595. The three-bus version with the Cell Bus and a single power supply is also available now for $2,595, or with two power supplies for $3,000. Customers can easily upgrade from the two-bus to the three-bus chassis by swapping out mid-planes. The TY400N and TY410N are the first in a series of communications modules housed in the 7400 WAN Champion. The TY400N, equivalent to TyLink's stand-alone ONS 400N, is a powerful two-port, soft-controllable T1 DSU/CSU (Digital (or Data) Service Unit/Channel Service Unit) A pair of communications devices that connect an inhouse line to an external digital circuit (T1, DDS, etc.). . Like the stand-alone version, the TY400N combines DTE applications flexibility and network access to T1 and Fractional T1 services. Pricing for the TY400N is $2,150. The TY410N, equivalent to the ONS 410N, includes SNMP management and is priced at $2,195.
