Orion offers T1 to E3
and E3 to T1 converters. Also available are E1 to T1, E1 to DS3,
Ethernet to E1, T1, E3 and DS3 Converters.
Orion 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.
Orion offers a wide
range of converters, as below:
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.
