Power System for Digital Loop Carriers

Valere Power’s new SLC Power Upgrade Series is a set of drop-in power system replacement kits for SLC Series 5 and SLC-96, two of the most widely deployed digital loop carriers in service today.

Designed in the 1970s and 1980s, the SLC systems have an installed base of several million lines. The systems help carriers breathe new life into these industry workhorses by addressing on-going reliability issues and enabling the provisioning of high-speed broadband services without installing expensive adjunct cabinets.

The smaller and more powerful Valere system can replace two of the original bulky SLC power plants providing enough rack space and power capacity to deploy DSL and optical equipment into facilities designed for POTS only. Valere's system uses the V-Series rectifiers, offering 92% power conversion efficiency, which reduces the heat load of the power system and also alleviates the additional thermal burden of the high-speed data circuits. DSL can now be provisioned to a much greater number of customers at a fraction of the cost of the traditional approach. The kits are compatible with all commonly available DSL products. The SLC Power Upgrade Series is certified NEBS level 3 compliant. This ensures that the systems meet highest standards for electrical and operational safety in communications networks.

The complete solution also includes dual 100-VA ring generators, an optional distribution panel with connections for up to four SLC channel banks and extra output connections for attaching back-up batteries or other equipment panels. The SLC power upgrade system has been engineered with connectors that match existing cabinet wiring for easy installation. The system can be used with either cabinet mounted or rack-based SLC systems. A total of 11 SLC Power Upgrade kits are now available for use in a variety of SLC Series 5 and the SLC-96 cabinet and rack configurations.
