TD-CNV ETH-8E

8E1 TO Ethernet Protocol Converter

Overview

TD-CNV ETH -8E is the most newly promoted product that can convert l-8E1 to 10/l00Base-T Ethernet, and vice versa. This protocol converter could support 1-8E1 to Ethernet, which extend the bandwidth to 16.348Mbps. It is widely used in two LAN connecting, remote monitor and video broadcasting.

Characteristics

• Ethernet Interface

Support 10/l00M, full-/half-duplex

> Support auto-negotiation and forcing mode by switch settings

> Built-in data flow statistic function, which can report the flow statistic of Ethernet receiving and transmission and error-package information

> Filter out over-long, over-short and CRC error Ethernet package

> Support up to 1536 byte Ethernet package

> Support PAUSE flow control function

> Built-in 1024 MAC addresses list, and auto-filtering and age function

> RJ45 connector, connect to PC with CAT-5 crossover twisted pair

• El Interface

> Provide 8 El interfaces complying with G.703 standard, 75Ω unbalance

> El lines should be used in pair, but support dissymmetrical

Auto detect the number of practicable line, the line can be shut down via network management

> AIS, LOS, LOF and error-code alarm, and error-code statistic data can be inquired via network management

> Provide auto shutdown function, the shutdown error rate threshold can be set via network management

> Provide remote loopback and error-code detection functions

> Stop Ethernet communication when local or remote El loopback

• Device Management

> Provide RS232 serial management interface

> Unique 8bits address is available for each device, one management system can manage up to 256 equipments together

> Abundant management information, including each El line status of local and remote ends, and Ethernet interface status and flow statistic
