VCL-2707, IEEE C37.94 to T1 Converter

Description

VCL-2707, IEEE C37.94 to T1 Converter is a ruggedized and robust, sub-station-hardened protocol converter that converts IEEE C37.94 Interface to a T1 Interface, and vice-versa. The VCL-2707 is designed for use in point-to-point applications.

The most common application for the VCL-2707 converter is for augmenting legacy IEEE C37.94 data transmission over a T1 network between two sub-stations. By installing a VCL-2707 converter, the existing IEEE C37.94 interfaces from protection relays can be transmitted over the T1 network without incurring large capex, or without the tiresome task of having to replace or rewire the IEEE C37.94 Relays which need to be interconnected to the far end substations over T1 (SONET) transmission links.

  • Number of C37.94 interfaces per card: 1 Tx, 1 Rx
  • Number of interfaces: 1 T1 (1.544 Mbit/s) interfaces
