The RB003 series is the cost effective IP over TDM converter, which supports the conversion from MAC frames to 1 to 16 E1 lines. Overview                      

The RB003 series is the IP over TDM converter, which supports the conversion from MAC frames to 1 – 16 E1 lines. The maximum bit rate is 31.68Mbps (16E1 lines). It not only provides alarms and status of the E1 line and Ethernet interface together with advanced management functions, but also supports the Local/ remote monitor and management via CLI commands. With low power consumption, high integration and well stability, it is a cost-competitive solution for the application in access network, such as the telecommunication, the electric power and the finance fields.

Compliant to international standards, the device can communicate with products from other vendors adopting the same standards.

Features

Compact design with 1U height, 19 inch, and can be installed on standard rack

Realizes Ethernet transparent transmission over 1~ 16 E1s

E1 interface

Provides 4/8/16 E1 interfaces, compliant to G.703, and balanced/unbalanced selectableJitter tolerance, jitter transfer characteristic and jitter generation fully comply with ITU-T G.823 and G.742 recommendationsSupports automatic removal and recovery of E1 channels that used for carrying payload. The E1 channels that have urgent alarm, such as LOS, AIS, LOF, LOMF, are removed automatically, and during this period, some Ethernet packets may be lost; It will be resumed when the fault dismisses .The differential delay between any two of the 16 E1 can be up to 220ms; when the factual differential delay exceeds 220ms, alarm is generated and Ethernet is cut off.The E1s in the local and remote side (E1 map) can be arranged arbitrarily

Ethernet interface

Provides up to 4 shared Ethernet interfaces, 4 electrical Ethernet interfaces(FE) or 3 FE plus one optical Ethernet interfaces(FX), compliant with IEEE802.3 serial standardThe FE interface supports auto-negotiation, which can work in 100M full/half-duplex, 10M full/half-duplex modeThe FX interface supports auto-negotiation, which can work in 100M full/half-duplex mode1024 MAC address table and 5-minute aging timeAccepts frames with length between 64 and 1916 bytes (otherwise filtering)Supports MAC address dynamic learning function with aging time of 5 minutesSupports pause flow control .
