Each unit supports 1 WAN interface (T1/E1, SDSL, SHDSL), 1LAN interface, and 12, 16, or 24 POTS interfaces via an RJ21 connector.These units are housed in a metal enclosure with an internal power supply.All units are based on a common core design consisting of a Motorola PowerQUICC CPU, 16 Mbytes of dynamic memory, and 4 Mbytes of FLASHmemory. Voice packetization and processing are handled by TexasInstruments Digital Signal Processors (DSP).High POTS Port FeaturesThe High POTS Port IADs provide a highly interoperable, cost-effectivevoice and 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.• For SHDSL, supports the following DSLAMS for ATM: Lucent, Nortel, andNokia• 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,or SHDSL• Supports data from POTS and 10/100Base-T customer premise interfaces• Compatible with standards-based IP, ATM, and Frame Relay WANprotocols• Interworking feature allows Frame Relay and ATM networks to exchangedata using either FRF.5 or FRF.8 protocol• Provides RJ21 POTS interface with Loop Start or Ground Start• USI supports V.35 and EIA-530• Provides dynamic and static IP routing and bridging capabilities• Provides firewall support via IP filtering• Offers DHCP and NAT to support IP address management• Supports MGCP and SIP with the flexibility to support TDM/VoATM/VoIPapplications all in one unit
