DS3 to E1 (E1 to DS3) Converters

Description

Valiant offers its DS3 to E1 converters which is primarily used to establish communication between two DS3 interfaces over an E1 network, or to connect a DS3 network to an E1 network. Valiant converter solutions provides upto from 8 E1 to 32 E1 interface to one DS3 interface and DS3 to upto 32 E1s. These converters may be installed in a 19 inch VCL-MegaConnect chassis in any "mix" for converting "n" x E1 interfaces to DS3 interfaces.

Note: The value of "n" is in multiples of 8 E1 ports.

The converter provides a simple and cost effective method to convert a DS3 stream to an E1 stream. The converter provides redundant power supply and mounts in a 19-inch 6U shelf. The converter 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.
