Ethernet
over E1 Converter
|
Description
| The Ethernet
over 1 E1 converter. The 10Base-T Ethernet interface to 1 E1 interface
converter which offers a channelized E1 and 10Base-T interface
conversion. This equipment offers electrical level conversion between
10Base-T Ethernet interface and a G.703 / E1 (or fractional E1)
interfaces.
The VCL-Ethernet over E1-E1/10(100) Base-T
Interface Converter provides the user with Ethernet over E1/E1
conversion enabling the user to transport Ethernet data over an E1 link.
The equipment be always installed and used in pairs, with one terminal
being installed at either end of the network.
The VCL-Ethernet over
E1-E1/10(100) Base-T Interface Converter is an Ethernet extension device
utilizing TDM telecom infrastructure (the telecom network of E1s, or of
PDH, SDH and E1/E3/SDH microwave etc. carrying E1s). It converts the
Ethernet data into E1 frame format for transmission over the existing
TDM (E1) links and then re-converts the E1 back into Ethernet data the
far-end terminal, to BRIDGE two Ethernet LANs over the existing E1-based
telecom network. The device can effectively utilize the redundant
bandwidth of telecom operators existing TDM network to transport
Ethernet data with low investment.

Features
- The maximum
transmission rate of Ethernet data over E1 links is 2.048Mbit/s
- E1 supports three
working modes of transparent transmission, framed (CCS/PCM 31) and
multiple framed (CAS/PCM30)
- Allows transparent
transmission of super-long frames in 1528 bytes (without CRC) and supports
Ethernet switches with VLAN function
- Automatic Ethernet
negotiation function. Supports 10M/100M and working modes of both
full-duplex and half-duplex
- Available with MAC
address list filtration, learning and updating functions
- Available with
auto-resetting function. When network port stops receiving or sending data
for about 8 seconds, the auto-resetting circuit will be able to start
automatically, to reduce and maintain workload for the system
- Equipment supports
two working modes of internal clock and network clock
- Supports RLOOP (E1
port external loop-back) function
Application
The equipment may
be used for the following purposes:
- Bridging Ethernet LANs over
existing TDM (E1) telecom network
- Extending Ethernet networks
utilizing TDM (E1) landline based telecom infrastructure
-
Using telecom
network of E1s/PDH/SDH microwave etc. carrying E1s to transport Ethernet
data
