Ethernet over T1 Converters
(IP over TDM) |
DescriptionValiant offers
its 4 x Ethernet over T1 (IP over TDM) package in a 1U
High, 19-inch rack-mountable chassis. It provides four
10/100BaseT (4 RJ-45) data interfaces on the user side which may
be used to transport Ethernet traffic over a T1 link. The
converter provides a simple and cost effective method to convert
and transport Ethernet data over a T1 link.
Ethernet over T1 is an Ethernet extension device utilizing
TDM telecom infrastructure (of T1, DS3, SDH or microwave links
carrying T1s ). It converts the Ethernet data into T1 frame
format for transmission over the existing TDM (T1) links and
then re-converts the T1 back into Ethernet data the far-end
terminal, to BRIDGE two Ethernet LANs over the existing T1-based
telecom network. The device can effectively utilize the existing
TDM network to transport Ethernet data with low investment.
The equipment must be always installed and
used in pairs, with one terminal being installed
at either end of the T1 link.
