Description

Network Adaptor

 

Brief introduction

JD-NAT-1100 network adaptor is the front connection equipment for DVB and SDH. It is applied to transform between ASI and DS3 signals. While in the part of program sending, it is applied for DS3 transmitter, transforming TS of MPEG-2 to DS3 to transmit; while in the part of program receiving, it is applied for DS3 receiver, transforming the DS3 data rate received from the equipment to MPEG-2 TS.

 

Features

• PCR jittering smoothly
• Transparent transmission, without ATM adapting processing, and directly mapping DS3 frame, via 45Mbits/s interface to transmit through network
• DS3 frame is in accordance with ITU-T G.752, ITU-T G.804
• Output DS3 is 44.736Mbits/s in transmitting
• Input/output code rate is MPEG-2 TS
• DS3 signal interface meet the standard of ITU-T G.703
• Input DS3 is 44.763Mbits/s in receiving
• Output DS3 is 44.763Mbits/s in sending
