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
