Ethernet over Multi E1 (ML-PPP) 10/100/1000BaseT to 8/16 E1 Interface Converter

Orion's VCL-ETH-8E1-ML / VCL-ETH-16E1-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 (Optional - as per user requirement). This equipment provides two Electrical Gigabit (1000/100/10M) Ethernet Interfaces (RJ-45) ports at the customer site.

This equipment is available in the following configurations:

E1 Interface Number	8 or 16
E1 Port Impedance option	75 Ohms (BNC) / 120 Ohms (RJ45) - Optional
Power Supply Options	AC or DC or AC + DC-Redundant AC = 100 ~ 240V AC, 50 / 60 Hz DC = 18 ~72V DC

This product is available in two versions:

VCL-ETH-8E1-ML	8 E1 Port Version
VCL-ETH-16E1-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.

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.
Interconnecting DSLAMS to Central Routers over PDH/SDH telecom networks.
Interconnecting IP-based GSM base stations.
Interconnecting WiMax base stations.

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
