Converter |
|
Product Overview
|
Orion Telecom Networks Inc.
offers VCL-ETH-8-ML / VCL-ETH-16-ML
Converter allows the user to send Ethernet data between two
points or between multiple points (maximum 12 directions), over
8 /16 E1 Links respectively. E1 Interfaces options are 75 Ohms /
120 Ohms (as per customer order). This equipment provides two
Electrical Gigabit (1000 / 100 / 10M) Ethernet Interfaces
(RJ-45). |

This equipment is
available in the following configurations:
|
E1 Interface Number
|
8 and 16 |
|
E1 Port Impedance option |
75 Ohms (BNC) / 120 Ohms
(RJ45) |
|
Power Supply Options |
AC / DC / AC+DC-Redundant
AC = 100 ~ 240 V AC, 50 / 60 Hz
DC = 18 ~72 V DC |
This product is available in
two versions:
|
VCL-ETH-8-ML |
8 E1 Port version |
|
VCL-ETH-16-ML |
16 E1 Port version |
The equipment can be installed (at
central site) and used with other equipment (i.e. with Ethernet over
Multi E1-DLX or VCL-ETH-FE1 at remote sites) to meet various
application requirements.
The Converter is an Ethernet
extension device, complied to IEEE 802.3 series standards, which
utilizes TDM telecom infrastructure (the telecom network of E1s, or
of PDH, SDH and E1/E3/SDH microwave etc.), complied to ITU-T G.7041,
G.7042, G.7043 and G.8040 standards, for carrying Ethernet data. 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 at the far-end terminal, to BRIDGE Ethernet LANs
over the existing E1 based telecom network. The device can
effectively utilize the existing TDM network to transport Ethernet
data at low investment.
Features and Highlights

PCM 31 formats (Auto Sensing)
- Supports VCAT (virtual concatenation) and LCAS
(link capacity adjustment scheme) protocol, and complies with ITU-T
G.7042 Specifications
- Supports auto removal of down E1 link and auto
insertion of recovered E1 link
- Mapping to E1 complies with ITU-T G.7043 and
G.8040 specifications
- Supports VLAN tagging as per 802.1Q
- User selectable ports for enabling / disabling
the QoS service
- Supports differential delay of up to 220ms on
E1 Links
- Complies with IEEE 802.3ab, IEEE 802.3u and
IEEE 802.3 specifications
- Supports X.86, LAPS and HDLC transmission
protocols
- Supports 10M / 100M, Half / Full duplex and
auto-negotiate mode.
- Configurable frame size upto 1552 bytes (MTU
size)
- Supports GFP-F encapsulation complying with ITU-T
G.7041
- Provides Automatic smooth adjustment of
Ethernet bandwidth as per the availability of carrier (E1) links
- Provides error frame statistic
- Supports automatic removal and addition of E1
Links without interrupting current services
- Available with MAC address list filtration,
learning and updating functions
- A large external SDRAM buffering for handling
data bursts
- 8000 MAC address learning
- Support Configurable MAC aging time 12 / 300
seconds
- Supports Internal synchronization clock
- Automatic Straight and cross-over cable support
(Auto-MDI/X)
Salient Features
-
Connect multiple sites (up to 12
directions) from a single central location
-
Data rate recovery after
restoration of lost E1 (LCAS)
-
Automatic data rate management
according to number of available E1 links
-
Maximum cable length supported (upto
1000 feets / 333 meters)
-
Support unbalanced bandwidth-If
Rx line of some E1 links are not working then the equipment will
keep working on Tx line, to use unbalanced bandwidth. i.e. If Tx
of a E1 line is not working out of 5 E1 available then the
equipment will continue to send data on 4 E1s and receive on 5 E1s
and vice-versa.

Application
The equipment may be used for the following purposes:
1. Bridging Ethernet LANs over existing TDM (E1)
telecom network.
2. Extending Ethernet networks utilizing TDM (E1)
landline based telecom
infrastructure.
3. Using telecom network of E1s/PDH/SDH microwave
etc. carrying E1s to
transport Ethernet data.
4. Interconnecting DSLAMS to Central Routers over
PDH/SDH telecom
networks.
5. Interconnecting IP based GSM base stations.
6. Interconnecting Wi-Max base stations.
In all cases the equipment must be always installed
and used in pairs, with one terminal being installed at either end
of the network.
