Historic high reliability and system redundancy
The Tellabs 1000 MSAP is a highly reliable access platform that has delivered lifeline POTS and 911 services for decades. This is possible because of its fully redundant architecture that allows for duplicity of powering (e.g. LPSU cards) and common control (e.g. CPU3 card). System redundancy can be provided by building two Local Exchange Terminals (LET) at the main central office, and sharing network resources across both systems with two Element Management System interfaces (e.g. IPMI3). In system configurations where expansion channel bank assemblies are needed, they too can also be outfitted with redundant power (e.g. RPSU) and common control (e.g. EBC3, ELU3). The net result is a highly reliable MSAP system with network up-time availability at 99.999%, which has been confirmed through actual field performance data and also validated by predictive calculations data.
Redundant and Diverse Copper Circuit Services
The Tellabs 1000 MSAP can provide an impressive number of legacy copper services including POTS, ISDN, DDS, T0 and T1 and the latest in xDSL technologies. Relative to the 911 PSAP redundancy and diversity application, the most common copper circuits needed are POTS, T1, PRI, 56K DDS and DS0 special services. These copper circuits are available today on the Tellabs 1000 MSAP with the full support of the Tellabs corporations from engineering, product management, sales, distribution, logistics, warranty, TAC and professional services. For connectivity to the DDS switches accessing the redundant Automatic Location Information (ALI) and Automatic Number Identification (ANI) databases, the Tellabs 1000 MSAP can provide 56K DDS circuits and T1 links to channel banks. Furthermore, the Tellabs 1000 has the flexibility to be equipped as a D4 channel bank or 1/0 Digital Access Cross-Connect (DAC). Finally, the Tellabs 1000 MSAP T1 cards can then provide the redundant and diverse access to the voice switches.
