E1 to T1 Converters

Description
T1 E1 Converters

Valiant T1 to E1 converter solutions offers data (frame) conversion between a T1 signal and an E1 signal. The T1 and E1 converter is available in 19 inch rack mount version. The converter provides a simple and cost effective method to convert a T1 stream to an E1 stream.

Valiant offers data (frame) T1 to E1 Converters:

  1. T1 to E1 Converters for data (frame) conversion

Each T1 < > E1 converter has an independent power supply and mounts in a 19-inch shelf. Upto 10, T1 < > E1 converters may be mounted in a single 19-inch shelf. The converters may be accessed by the user for configuration and monitoring through a Windows based GUI that is shipped with the system. It may be also accessed remotely over a TCP-IP network (optional extra).

Valiant T1 to E1 converter solutions also offers upto 64 E1 or T1 interfaces that may be installed in a 19 inch VCL-MegaConnect chassis in any "mix" for converting "n" x E1 interfaces to "n" x T1 interfaces. (Note: The value of "n" is in multiples of 8 E1 ports or 8 T1 ports). The converter provides a simple and cost effective method to convert a T1 stream to an E1 stream.
