The Ethernet over T1 Converter
allows the user to send Ethernet data, between two points, over T1
links. T1 Interface is 100 Ohms. Ethernet Interface options may be
ordered as 10/100 Base-T Electrical Ethernet or 100Base-FX Optical
Ethernet over 850nm/1310nm/1550nm single mode optical fiber.
The equipment be always installed and used
in pairs, with one terminal being installed at either end of the T1
link.
The
VCL-Ethernet over T1 Converter is an Ethernet extension device utilizing
TDM telecom infrastructure (the telecom network of T1, or of PDH, Sonet
and T1/DS3/SDH microwave etc. carrying T1). It converts the Ethernet
data into T1 frame format for transmission over the existing TDM (T1)
link 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.
|
Application
The equipment may be used for the following
purposes:
- Bridging Ethernet LANs over existing TDM
(T1) telecom network.
- Extending Ethernet networks utilizing TDM
(T1) landline based telecom infrastructure.
- Using telecom network of T1/PDH/SDH
microwave etc. carrying T1 to transport Ethernet Data.
In all cases the equipment must be always
installed and used in pairs, with one terminal being installed at either end
of the network.
Technical Features
- The maximum transmission rate of Ethernet data
over T1 links is 1.544 Mbit/s.
T1 supports two working
modes of transmission. Un-Framed/Transparent and
