Telco Systems, Legacy Division Launches New IEEE C37.94 Compliant Teleprotection Module for the Access60 Integrated Access Device

MANSFIELD, MA, May 13, 2013 – Telco Systems Legacy Division, a provider of widely deployed and proven voice, data and Ethernet service solutions for T1/E1, DS3 and SONET/SDH TDM-based network access, announced today the launch of a new IEEE C37.94 teleprotection module for the Access60 Integrated Access Device (IAD). The module offers two C37.94 interface ports, supports data rates from 64kbps to 768Kbps and maintenance features like local and remote loopback, laser control and alarm indicators.

Utilities teleprotection communications circuits are mission critical, requiring reliable fail safe operation, service predictability with stringent latency and end-to-end delay specifications. Teleprotection services traditionally operated over copper-based X.21, V.35 or E&M(TO) interfaces, which are susceptible to RF and EM interference. The new module is IEEE C37.94 compliant and allows transmission of synchronous (N x 64 kilobit) data between a protection relay and a multiplexer over fiber, improving interference isolation and security.

“With the addition of the new C37.94 interface module, utility companies can now directly interface their installed base of Access60’s to their teleprotection devices optically, eliminating the need for additional devices and minimizing interference related to copper circuits and improving channel security. Additionally, Access60’s built in cross-connect capability allows for efficient use of upstream facilities” said David Lee, VP Business Development, Telco Systems Legacy Division.
