Ethernet to E1 Converter (RB007)

Overview

RB007 is an Ethernet to E1 converter with 4 copper fast Ethernet interfaces and one 75Ω&120Ω E1 interface, supports CLI command and SNMP_V1&V2 protocol to perform perfect management functions. It is featured by ultra-compact, cost-effective and low power consumption, which is ideal for application areas such as network access, transparent LAN service and LAN extension.

Feature

• Standard rack with 1U height and 19 Inch width
• Ethernet interface
• Four fast Ethernet interfaces compliant with IEEE 802.3/802.3u, adopts RJ45 connector, supports auto-negotiation, which can work in 100M full/half-duplex, 10M full/half-duplex mode
• Unicast, multicast and broadcast frame
• Accepts frames with length between 64 and 1536/2031 bytes (otherwise filtering)
• PAUSE flow control and broadcast storm filtering control.
• Auto MDI/MDX function
• 2K MAC address table
• Supports MAC address dynamic learning function
• Supports port-based VLAN and IEEE802.1Q tag-based VLAN
• VLAN table capacity is 15
• Supports port rate control
• Supports port mirroring.
• Provides performance statistic for each Ethernet interface
• Perfect Ethernet loop processing
• E1 Port
• Supports Both BNC interface (75Ω) and RJ48C interface (120Ω )
• 2.048Mb/s for unframed mode, under HDLC framed mode, the bit rate of N×64kbit/s（N=1~31）is adjustable, and the PCM30/PCM31 mode is optional
• Encapsulation
• GFP-F encapsulation compatible with ITU-T G.7041 recommendation
• HDLC encapsulation compatible with RJ017
• E1 loop and Embedded BERT (Bit Error Ratio Tester) testing function
• Supports Link Fault Pass-through function(LFP), when E1 LOS\LOF\AIS\E1-RAL occurs, the Ethernet interface can be LINKDOWN
• Management
• One RS232 management interface(CONSOLE) used for CLI management
• Any one of the Ethernet interface(FE1~FE4) as management interface, supports SNMP_V1 and SNMP_V2 protocol
• Necessary E1 alarm indications such as LOS, LOF, AIS and CV
• Supports time management function
• Supports hot-spare power, the power consumption is less than 5W
• -48V DC single power access;
• -48V DC double power access;
• 220V AC single power access;
• 220V AC double power access;
• -48V DC+220V AC double power access;
