Product Introduction

ETV protocol converter equipment is a device that implements Ethernet extension by means of telecommunication lines (E1 or transmission network carrying E1, such as PDH, SDH, microwave, etc.). It converts the Ethernet frame format into E1 frame format for transmission, and then restores the E1 frame format to the Ethernet frame format at the opposite end, so as to realize the transmission of Ethernet data on the E1-based telecommunication network, which can be very convenient Use the existing abundant E1 resources in the public network to quickly build a broadband Ethernet data network.

Main Feature

1. It can realize framed transmission and unframed transmission of Ethernet data in E1 line, with a bandwidth range of 64Kbps-2048Kbps.
2. With Ethernet auto-negotiation function, it supports full duplex/half duplex working mode.
3. The Ethernet port supports AUTO-MDIX (pass-through and crossover line adaptive).
4. It can transmit IEEE 802.1Q ultra-long frames (the longest packet is 2024byte), and supports Ethernet switches with VLAN function.
5. With automatic reset function, it will never crash.
6. Abundant Ethernet data prompt function, real-time prompt of data communication status.
7. With local data frame filtering function.
8. With the detection function of E1 circuit, it is convenient to open.
9. DC -48V has no positive and negative poles, easy to install and maintain.
10. Free of any debugging, plug and play.
