RC -FE E fast Ethernet to E converter User guide Beijing Raisecom Science Technology Co ltd CContent Chapter Overview Chapter Connection features Chapter Installation and test Chapter Introduction of DIP- Switch Chapter Troubleshooting CChapter Overview Description RC - FE E M auto-sensing Ethernet interface converter of Ethernet to E is one product of RC series converters made by Beijing Raisecom Science Technology Co ltd It provides a simple solution to enable Ethernet access by using E links for signal transmissions RC -FE E is modular device It can provide central SNMP management solution when it is plugged in RC - that is slot chassis It can support remote management when it works in pair with RC -FE E Speci ?cation E interface RJ- balanced Bit rate Kbps ppm Line code HDB Compliance ITU-T G ITU-T G Other features Real-time BER detecting and E links auto protection auto-reset Resistance for drift of UI the ability of counteraction of jitter and drift Selectable BER threshold of link auto- reset - default or - Fast Ethernet interface Interface RJ- cat cat e cables available supports link distance up to m Bit rate selectable Auto-sensing M Mbps or manual con ?guration Duplex type Full Half duplex auto-negotiation or manual con ?guration Compliance IEEE IEEE u Other features Supports maximum frame size up to bytes Supports IEEE d Spanning Tree q VLAN Supports K MAC address table address ?ltering improve e ?ciency of E link Supports Auto-MDI MIDX auto-negotiation Supports Link Fault Pass-though LFP Provides Mbit SDRAM for reducing the network congestion Features C forward features Maximum forward speed in each E link supports up to Kbps Maximum forward speed for E link supports up to ? Kbps when fully loaded The forward bit rate is auto allocated depending on the real-time status of E links Bandwidth auto-adjustment RC -FE E supports E links bandwidth auto-adjustment If any of the E links disconnected or when it is just back to normal from disconnecting transmission can be automatic achieved trough connecting E link and bandwidth can be adjusted automatically but at least E link has to connect Every E link provides Mbps bandwidth If E links are working properly M bandwidth can be provided in total E link ??working ? means the two converters have no alarm occurs in E link Fault Pass Through RC -FE E provides Fault Pass Through FPT for special requirements e g which need Spanning Tree superior switch network management record The FPT de ?ned as If alarm occur on all E links then all the links disconnect FPT function will suspend the UTP port and disconnect the links with Ethernet switches and NIC until any of E link no alarm occurred then system is back to default status FPT set ??close ? as default status it is convenient for those customers who have no special requirements Please see the manual about the switch setting of the panel if need it Front panel and LED indicator E link E balanced interface
