T1 to E3 and E3 to T1 Converters
Valiant's
T1 to E3 and E3 to T1 converter solutions provides upto from 8 E1 to 48 T1 interface to E3 and
E3 to upto 48 T1s. These converters may be installed in a 19 inch VCL-MegaConnect chassis
in any "mix" for converting "n" x T1 interfaces to E3 interfaces.
(Note: The value of "n" is in multiples of 8 T1 ports). The converter provides a
simple and cost effective method to convert a T1 streams to an E3 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.
