This provides the user with CPE investment protection,reduced inventory and training requirements, as well as a built-in migrationpath from TDM or VoATM to VoIP by a simple reconfiguration of the unit.No costly truck rolls or forklift upgrades are required.The 2000 Series IADs are ideal for service providers, offering smallbusinesses or home offices high-quality voice and data service over broadbandcircuits. The 2000 Series supports any POTS device via a voice subsystem,and any IP-based computer system (Ethernet printers; personal computers,including Windows, Macintosh, Unix, Linux, etc.; network file servers, andother network devices via a LAN subsystem.Interfaces and Features of theLow POTS Port Platform ArchitectureLow POTS Port Platform ArchitectureThe Low POTS Port IADs are based on a single-board, fixed-configurationarchitecture. Each unit supports one WAN interface (T1/E1, SDSL, ADSL,SHDSL), one LAN interface, and four or eight POTS interfaces. The units arehoused in a plastic enclosure with an external power supply.All units are based on a common core design consisting of a Motorola PowerQUICC CPU, 16 or 8 Mbytes of dynamic memory, and 2 Mbytes of FLASHmemory. Voice packetization and processing are handled by TexasInstruments Digital Signal Processors (DSP).Low POTS Port FeaturesThe Low POTS Port IADs provide a highly interoperable, cost-effective voiceand high-speed data integration solution that is compatible withindustry-leading DSLAM and Voice Gateway manufacturers. These IADsprioritize voice packets and dynamically allocate bandwidth between voiceand data services. Features include the following:• For SDSL, supports the following DSLAMs:• ATM: Lucent, Nortel, and Nokia• Frame Relay: AccessLan, CopperMountain, and Paradyne.• Supports the following Voice Gateways: CopperCom, JetStream, TdSoft,Broadsoft, MetaSwitch, Cirpack, NuERA Tollbridge, Nortel, GeneralBandwidth, Accelerated• Provides seamless voice and high-speed data integration over SDSL, T1/E1,ADSL, or SHDSL• Supports data from POTS and 10/100Base-T customer premise interfaces• Compatible with standards-based IP, ATM, and Frame Relay WANprotocols• Provides RJ11 POTS interface with Loop Start or Ground Start
