Teleprotection Equipment
IEEE C37.94 Optical Interface

Product Overview

Aries Telecom offers VCL-TP, Teleprotection Equipment which is an extremely reliable and flexible product that offers up to 8, 2-way independent command channels which can be operated selectively or simultaneously over a wide choice and a variety of transmission interfaces.

The VCL-TP, Teleprotection Equipment offers a choice of transmission interfaces which include the IEEE C37.94 compliant optical fiber interface for transmission over Multi-Mode and Single Mode Optical Fiber pairs, as well as the G.703, 64Kbps co-directional digital data interface and the  2.048Mbps E1 interface options.

VCL-TP, Teleprotection Equipment may be used independently, in a standalone point-to-point application, or as an integrated part of the GL-MX Version 6, E1 Voice and Data Multiplexer solution over SDH or PDH data networks.
