1 Broadband Access for Voice and Data Carrier Class, B r o a d b a n d M u l t i s e r v i c e Access Platform

2 Total Access: Meeting Carriers Needs Today and into the Future ADTRAN s Total Access System of multiservice access p l a t f o r m s, i n t egrated access devices, and concentrators is the industry s most flexible solution for deploying the latest loop technologies. Its modular and compact design provides carriers with more deployment options than ever before all with minimal capital outlay. That s because Total Access is a grow-as-you-go system, allowing carriers to purchase only the capacity they need, when they need it. P l u s, Total Access simplifies the migration from TDM to packet networks and is easily managed from a centralized location. These system highlights give carriers more control over the entire network. Backed by ADTRAN s outstanding technical support, the highest product quality, and an industry-leading 10-year warranty, Total Access lets carriers provide service with confidence. Choose ADTRAN for reliability all day, every day Total Access 3000: A Sound Investment Total Access 3000 is an intelligent, open-arc h i t e c t u re, Carrier Class multiservice access platform for deploying Hi Cap and DSL services. An integral component of ADTRAN s Total A c c e s s System of multiservice access platforms, integrated access devices, and concentrators, Total Access 3000 offers unpre c e d e n t e d f l e x i b i l i t y, along with multiple service options and management capabilities. This compact, modular device is a single platform for delivering manageable, profitable services now and into the f u t u re. Total Access 3000: Performs as a DSLAccess Multiplexer (DSLAM), an Off i c e Repeater Bay (ORB), an M13 multiplexer, an STS-1 or OC-3 SONET multiplexer, or an ISDN DLC. Provides TDM, Frame Relay, or ATM network interfaces. Includes 1:1 Automatic Protection Switching (APS). Offers the industry s most flexible management options.

3 Proven Leadership, Solid Reputation When service providers choose ADTRAN, they know they re getting experience and expertise that no other vendor can offer. That s because ADTRAN has more than two million local loops operating worldwide, p r oviding value and dependability through engineering excellence and customer-oriented service. These successes have earned ADTRAN longstanding relationships with every major Incumbent Local Exchange Company (ILEC) and many emerging Competitive Local Exchange Companies (CLECs). Open Architecture As part of its commitment to open standards, ADTRAN makes the Total Access Developer s Kit available to equipment vendors to design compatible plug-ins or interoperable platforms. ADTRAN provides this information in an effort to enhance the marketplace by promoting competition, increasing innovation, and lowering overall deployment costs. Other benefits of s t a n d a rdized equipment include easy system integration, simpler network configurations, and lower network maintenance costs. The leader in DSL deployment and number one in each of our key technologies DDS, ISDN, and HDSL ADTRAN offers the most comprehensive line of Central Office (CO) collocation, network termination, and access equipment available from a single source. That s why service providers rely on ADTRAN. Seamless Migration to Packet-Switching Networks The Total Access System consists of platforms that support the industry s migration from Time-Division Multiplexing (TDM) to packet switching (ATM and Frame Relay). Unlike TDM, which allocates a fixed amount of bandwidth re g a rdless of whether data is being sent, packet switching transmits bursts of data along the most efficient path. Multiple connections can share a channel, so carriers can provide more cost-effective services. By deploying Total Access 3000, service providers avoid the need to change platforms to accommodate TDM to packet migration. That translates into substantial savings of time and money, as packet switching becomes more pervasive.

4 D e p l oying Flex i b l e Options from a Single Platform TDM Networks Total Access 3000 provides a broad range of options for management, network, and local loop interfaces. Its flexibility allows service providers to deploy a wide range of local loop technologies in their TDM networks with many options for management and network interfaces.

5 ATM/Packet Networks Supporting ATM/Packet with Total Access 3000 Total Access 3000 configured as a DSLAM delivers DSL services across a DS3 network interface. Its open-architecture backplane provides highly reliable operation across a large number of interfaces. Total Access 3000 offers comprehensive support for high-speed data services using cell or packet switching.

Total Access 4303 Concentrator Total Access 4303 is a GR-303 concentrator with Digital Cross Connect c a p a b i l i t y. The unit supports concentration ratios from 1:1 to 1:16. Designed for service providers deploying analog voice services, To t a l Access 4303 allows efficient use of analog switch re s o u rces. Total A c c e s s 4303 is used in the CO as a 3/1/0 cross-connect or GR-303 (128-port capacity) concentrator supporting multiple integrated access devices. Total Access 1500 Acompact, versatile platform for deploying a variety of services, To t a l Access 1500 integrates the functionality of many carrier products into a single high-density chassis. Total Access 1500 can be used as a small Digital Loop Carrier (DLC), a Special Services delivery system, or as a mini DSLAM. Total Access 1500 s small footprint makes it the perfect choice to deploy in c rowded Remote Terminals (RTs) or Central Offices (CO). Up to five times as dense as a D4 in CO applications, Total Access 1500 greatly reduces the amount of CO space needed to deploy special services. The system is easy to provision and manage, offers flexible service options, and boasts a low cost per port Total Access 750/850 Total Access 750 and Total Access 850 are integrated access devices with f e a t u res for advanced voice and data services, Total Access 750 and To t a l Access 850 benefit every service provider (CLEC, ILEC, or ISP) by pro v i d i n g c o s t - e ffective, industry-compatible solutions for TDM or ATM network i n f r a s t ru c t u res. Total Access 750 for Price-Sensitive TDM Applications Total Access 750 allows cost-effective deployment of TDM voice and data at the customer premises. Combining voice and data traffic over a single T1 terminating at the end-user s site, Total Access 750 is an ideal solution for small- to medium-size business applications. Total Access 750 supports a b road service offering including analog voice, NxData, Fractional T1 (DSX-1), ISDN, and DDS. Total Access 850: Total Access 750 plus In addition to providing a platform for analog voice support, Total Access 850 has a built-in IProuter, management, and a migration path to ATM. Service providers can deploy Total Access 850 and, using inband management, turn features, functions, and access ports on or off based on customer requirements. The Total Access 850 Router Control Unit (RCU) common module can be upgraded to packet-based services, including ATM, by simply flashupgrading the RCU. This allows Total Access 850 to support VoDSL applications and fully use the benefits of ATM dynamic bandwidth allocation, so network resources are used more economically.
