1. Product Description

SVPE (Super Virtual Private Ethernet Equipment) is a converter for interconnecting Fast Ethernet (FE) with E1 which is based on Ethernet-over-PDH (EoPDH) technique, a new breed of products integrating advanced Ethernet bridging with fully channelized TDM capabilities.

SVPE18M series, independently developed and produced by EZWELL with self-own IP chipset, are inverse multiplexer for providing Ethernet services over single E1. The SVPE18M  series from EZWELL will help carriers and enterprises to make full use of the traditional TDM network in this TCP/IP Era, utilize legacy E1 resources in the public network to build broadband Ethernet data network rapidly.

The SVPE18M series Interface Converter is an Ethernet extension device utilizing TDM telecom infrastructure (the telecom network of E1/PDH/SDH carrying E1). 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 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.

SVPE18M series in compliant with ITU-T G.8040 standard – to encapsulate and map Ethernet packets into PDH timeslots. The equipment provides 1×10/100BASE-TX Fast Ethernet interfaces SVPE18M series can interoperate with the third party devices with the same standard.

6. 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 E1/PDH/SDH microwave etc. carrying E1s to transport Ethernet data.

In all cases the equipment should be always installed and used in pairs, with one terminal being installed at both end of the network.

Below are sample typical applications using SVPE18M in SDH transmission network.
