ETH over 4/8/16E1
Ethernet over 4/8/16E1 Converter--support Point to MultiPoint Convergence


1. Overview

The FB003 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.


2. Feature

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 selectable

      ---> Jitter tolerance, jitter transfer characteristic and jitter generation fully comply with ITU-T G.823

             and G.742 recommendations

      ---> Supports 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 standard

      ---> The FE interface supports auto-negotiation, which can work in 100M full/half-duplex, 10M

              full/half-duplex mode

      ---> The FX interface can work in 100M full/half-duplex mode

      ---> 1024 MAC address table and 5-minute aging time

      ---> Accepts frames with length between 64 and 1916 bytes (otherwise filtering)

      ---> Supports MAC address dynamic learning function with aging time of 5 minutes

      ---> Supports pause flow control

 

Compliant to ITU-T standards

      ---> GFP-F encapsulation specified in ITU-T G.7041

      ---> Virtual concatenation (VCAT) specified in ITU-T G.7043

      ---> Link Capacity Adjustment Scheme (LCAS) specified in ITU-T G.7042

      ---> GFP frame mapping into single E1 channel specified in ITU-T G.8040

      ---> GFP frame mapping into nxE1 channel specified in ITU-T G.7043

 

Supports hot-spare power, the power consumption is less than 8W

      --->  -48V DC single power access

      ---> 220V AC single power access

      ---> -48V DC&220V AC double power access

      ---> -48V DC double power access

      ---> 220V AC double power access


3.Application

Figure 3-1 illustrates a typical point-to-point application. With FB003 system, the Ethernet is transferred over 1~16E1s. Compliant to the international standards, the FB003 can communicate with products from different vendors, adopting the same standards.

As shown in Figure3-2, Figure3-3 with EoPDH technology, the remote Ethernet service can be transmitted and converged into the service center (Switch) by FB001N or FB002(point-to-multipoint).
