Description
E1/T1 G.703 To Ethernet Converter
Introduce
Features
IC-T1L is a double protocol Ethernet converter using one E1 line or T1 line to transmit Ethernet data and based on ASIC circuitry design technology. Its purpose is to extend transmission distance and applicable range. It is collocated with E1/HDB3 or T1/B8ZS as line interface, E1 can be either framed N*64Kbps (N=1-31) or unframed 2048Kbps, which are also known as channelization and unchannelization. Under the framed mode, it supports options of CAS/CCS (30 & 31 time slot), and CRC4 auto-adapt. T1 connects remote LAN through fully transparent unframed 1.544Mbps bandwidth. Transmission clock can be recovered from receiving signal G.703 lines and also can work in internal clock mode. Ethernet supports 10/100M auto-adapt.
Overview
IC-T1L has local and remote loops, so user can test circuitry and diagnose failure conveniently to achieve port-to-port integrity test. There are rich indicators on the front panel to display working status and alarm signals.
IC-T1LR is card converter whose every 19 inch rack can be fixed 16 cards. It has double power supply, DC -48V or AC 220V. It is suitable for computer center.
