Interfaces and Features of the
High POTS Port Platform Architecture
High POTS Port Platform Architecture
The High POTS Port IADs are based on a single-board, fixed-configuration 
architecture. Each unit supports 1 WAN interface (T1/E1, SDSL, SHDSL), 1 
LAN 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 Power 
QUICC CPU, 16 Mbytes of dynamic memory, and 4 Mbytes of FLASH 
memory. Voice packetization and processing are handled by Texas 
Instruments Digital Signal Processors (DSP).
High POTS Port Features
The High POTS Port IADs provide a highly interoperable, cost-effective 
voice and high-speed data integration solution that is compatible with 
industry-leading DSLAM and Voice Gateway manufacturers. These IADs 
prioritize voice packets and dynamically allocate bandwidth between voice 
and 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, and 
Nokia
Supports the following Voice Gateways: CopperCom, JetStream, TdSoft, 
Broadsoft, MetaSwitch, Cirpack, NuERA Tollbridge, Nortel, General 
Bandwidth, 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 WAN 
protocols 
Interworking feature allows Frame Relay and ATM networks to exchange 
data 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/VoIP 
applications all in one unit
