As a cost effective solution for the traditional telecom services migrate to the IP packet networking technology,    4 E1 to Ethernet Converter with 75ohm or 120ohm port adopts the innovative TDM over IP technology, it transports the legacy E1/T1 data through the existing Ethernet or IP network.

The    4 E1 to Ethernet Converter with 75ohm or 120ohm port is the new generation of the TDM over IP equipment with IP circuit emulation that supports transportation of four E1/T1 and two local Ethernet ports over Ethernet or IP network. The uplink ports and user data ports are IEEE 802.3 compliant, 10/100BaseT auto-sensed Ethernet port.

The state-of-the-art design provides the highest availability with the accurate timing signal and data bit stream reconstruction. Predefined system parameter profiles that according to different application requirement; ultimately simplify the installation process and saving the maintenance cost.

Telecom and Enterprise users can save a lot of access and equipment costs and generates new revenue by offering different types of service over existing Ethernet networks. It is also suitable for connecting to the wireless equipment to achieve fast deployment of E1/T1 services. One particular application is to build E1/T1 links with low cost Wireless LAN bridges,
replacing much more costly microwave radios. Operators can use BD-4E1-IP to provide legacy TDM services over wired or wireless packet network.

FAQ

1.How can i get a sample ?

You need place sample order to us.We will arrange the sample production for you.

2.Could you do design for us?

yes, we can do artwork including printing, logo etc. for you, if you provide us the content and tell us where to put.

3.How can we place order? 

After we made agreement on the product' parameters, we will make proforma invoice  for your confirmation.when we got your advance payment (deposit) we will arrange the production and delivery.

If you have your own ship forwarder, we will use your ship forwarder to delivery goods. if you don't have ship forwarder, then when the goods arrived at Destination port, you must find a  ship forwarder help you clear the custom.

4.How about the shipping?

For small orders, we will send the goods by International Express like HK Fedex, DHL, TNT or UPS. usually it takes about 7work days to arrive.If big quantity we will ship by Ocean transportation, it takes one month to arrive. if urgnet, you can select shipping by Air, but freight charge will be more expensive.

6.what's your products' advantages ?

A. good quality and competetive prices.

B. Strictly quality control when producing.

C. Professional team work, from design, development, producing,assemble,packing and shipping.

D. Aftersale services, if there is quality problem, we will offer you replacement for defective quantity.
