DS3 to E1 (E1 to DS3) Converters
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.
