4 Distributed Access Solutions for the Local Loop A DTRAN s Total Access System offers carriers and enterprises the industry s most comprehensive feature set, optimized for every local loop application: The industry s most complete system of access products with support ranging from fiber optics to DSL to POTS Versatile platforms designed for specific applications using the latest, industry-standard loop technologies such as HDSL2, SHDSL, and ADSL Compact form factors, optimizing space in crowded COs and RTs Scalable, grow-as-you-go architecture for deployments based on actual need, reducing initial turn-up and per-port costs Hot-swappable, modular design for quick and easy upgrades and maintenance Remote management using industry-standard protocols TL1 and SNMP System Benefits The Total Access System benefits both carriers and subscribers with high-performance, cost-saving deployment solutions. Total Access ensures: Easy deployment of voice, data, and converged applications to business or residential customers Minimal capital outlay and investment protection through modular technology upgrades Interoperability with equipment from other vendors through adherence to industry standards An easy migration path from TDM to packet switching networks Simplified network management using an intuitive, graphical user interface One-stop shopping for equipment, installation, training, and support Strategic partnership with ADTRAN, a leader in local loop technologies NEBS Level 3 and UL 1950 compliance for the highest reliability and safety An ADTRAN White Paper 30

5 Application Highlights DSL Deployment ADTRAN DSL solutions provide high-speed loop access for the most bandwidth-intensive applications. The Total Access System enables cost-effective solutions for VoDSL, Internet, video, VPN, and more. The Total Access DSLAM is the industry s most compact and cost-effective means of deploying DSL services to an extremely large customer base. ADTRAN s leadership in the development of today s industry-standard DSL technologies makes ADTRAN uniquely qualified to provide the most comprehensive DSL solutions available. Extended Range The Total Access System is based on a distributed architecture, enabling the deployment of equipment in COs and remote terminals that require temperaturehardened equipment. Spectrally friendly technologies using the robust TC-PAM modulation technique extend range without degrading signals. Standards-compliant repeaters increase reach even further, allowing service providers to serve customers in traditionally hard-toreach locations. 4 Distributed Access Solutions for the Local Loop

6 Capacity Relief Total Access System solutions are extraordinarily efficient in their use of both physical space and copper facilities. Compact in size and port density, these solutions optimize space in crowded COs and RTs. Their support for the latest copper-saving technologies, such as ANSI-standard HDSL2 and ITU-standard SHDSL, make the most of valuable copper resources. An ADTRAN White Paper 5

7 Packet Solutions Total Access packet solutions support virtually every packet-based application in your next-generation network. Total Access IADs support applications such as VoDSL and VoATM. The Total Access Packet DLC takes traditional voice circuits and interfaces them with an ATM network using an innovative voice cell processor. The Total Access System even offers an easy migration path from TDM to packet switching for service providers planning to make that transition. Total Access Building Blocks Total Access System building blocks combine to form the industry s most complete solution for virtually any local loop application. Deployed in central offices, remote terminals, or MTU s, the system encompasses carrier-class broadband and narrowband access platforms, multiplexers, IADs, and concentrators. Total Access system management and professional services complete the picture for a "one-stop shopping" deployment solution. Broadband and Narrowband Access Platforms ADTRAN s compact, broadband multiservice access platform, Total Access 3000, is ideal for today s deployments and equipped for tomorrow s technologies. The platform can serve as a Digital Subscriber Line Access Multiplexer (DSLAM), an Office Repeater Bay, an M13 multiplexer, a SONET Network Element, or an ISDN Digital Loop Carrier (DLC). ADTRAN s narrowband multiservice access platform, Total Access 1500, is a smaller yet still powerful platform with the versatility for numerous applications. It can be used as a small DLC, a special services delivery system, or as an IAD. Total Access 1500 provides up to four times the port density of a traditional DLC in remote terminal applications and up to five times the port density of a D4 in central office applications, greatly reducing the amount of space needed to deploy POTS and special services. 6 Distributed Access Solutions for the Local Loop

8 Modular IADs As the IAD market leader, ADTRAN offers a selection of traditional TDM-based and next-generation ATM-based IADs. These compact devices play a pivotal role in the distributed network, enabling cost-effective deployment of voice and data services. Combining voice and data traffic over a single T1 terminating at the end-user's site, Total Access 750 supports a broad offering of voice and data services and uses traditional TDM circuit switching. Another IAD, Total Access 850, includes a built-in IP router and management options, and offers a simple migration path from TDM to ATM. Interoperability with major voice gateways and DSLAMs makes this device well suited for applications such as VoDSL and VoATM. Fixed-port IADs The Total Access 600 series of cost-effective, carrier-class IADs provide interfaces for T1, ADSL, SHDSL, or SDSL and are compatible with industry-leading voice gateways and DSLAMs. Features include integral analog voice (FXS) interfaces, a built-in IP router, and V.35 port for synchronous data applications. Assured Dialtone using a Lifeline POTS port, battery backup, and a rugged metal casing provide added investment protection. Total Access 500 series IADs are designed for international VoDSL applications. Compact yet durable, these IADs offer a variety of user configurations including interfaces for ISDN BRI S0, Nx56/64 V.35, POTS, PRI, and integral routing. This equipment is fully interoperable with today s commonly deployed V5.2 voice gateways and DSLAMs, guaranteeing VoDSL functionality in multi-vendor environments. Outside Plant Access Terminal Total Access 1000 is a high-performance Outside Plant Access Terminal for efficient deployment of voice and data services. This compact, versatile platform uses span powering to deliver voice and data services to customers at remote locations in a self-contained, hardened enclosure. Total Access 1000 supports HDSL and HDSL2 transport technologies and delivers services including POTS, ISDN, ADSL, and SHDSL. GR-303 Concentrator Total Access 4303 is a compact, cost-saving device used in voice concentration applications. Designed for service providers deploying analog voice services, Total Access 4303 allows efficient use of analog switch resources and supports multiple IADs and DLCs. Network Management The Total Access Element Management System (EMS) eases the complex task of network management, providing the carrier with configuration, performance, network assurance, and provisioning features. Total Access EMS manages the operations of networks containing one or more Total Access platforms. Professional Services ADTRAN professional services simplify the deployment of the Total Access System. The Total Access Services Group custom-configures system components, including elements from third-party vendors, to provide specific voice and/or data applications. The pre-assembled, preconfigured system is delivered to the installation site. ADTRAN can then perform EF&I for a complete, turnkey solution. M13/STS-1 Multiplexer The Total Access MX2800/MX2810 is an M13 multiplexer that meets the most stringent carrier-class requirements. The multiplexer offers comprehensive management and configuration options. Measuring only one rack unit high, this compact device is a powerful tool for consolidating 28 T1 signals or 21 E1 signals onto a DS3 or STS-1 circuit. Carriers seeking to maximize their copper investment will find that the Total Access MX2800 will pay off quickly. An ADTRAN White Paper 7
