1. LB-300 Overview
1.1. General Description of LB-300
LB-300 is a smart companion for NuDOG-301 for enhancing
networking product function tests and network environment
measurement test.
With its single 10/100/1000 Mbps RJ45 port, LB-300 is a
good solution for loopback test in network environment.
LB-300 can filter out broadcast, multicast and null DA
(Destination Address) packets and re-send the rest of the
incoming packets back to the same network cable by two
selective methods: resends directly (Layer 1 Loopback) or resends with switched DA/SA
(Destination/Source MAC Address) and recalculated CRC for different applications (Layer 2 Loopback)
of the test.
For fixed network provider, Telecom and ISP Company, LB-300 and NuDOG-301 are suitable to test the
throughput and latency performance of leased line or ADSL. Both LB-300 and NuDOG-301 act as packet
generator that is located at CO and CPE side for packets transmission and receiving.
The distance and cable quality is the key factor that affects the transmission bandwidth of ADSL and
leased line. The bandwidth is not guaranteed even though the bandwidth allowed is configured at central
office. By a pair of LB-300 and NuDOG-301, technical personnel can test and realize the maximum
downstream and upstream bandwidth available of the transmission media, such as ADSL by telephone
line or wireless transmission for public service. The solution can verify if the transmission bandwidth
meets the requirement that customer applied, or realize the maximum available bandwidth of the leased
line or ADSL network if bandwidth from central office is unlimited.
With this affordable price and excellent functions for network measurement and test on-site, LB-300 and
NuDOG-301 are one simple yet effective solution for data transmission test in cable wiring phase or
troubleshooting phase for both WAN and LAN.
