SNMP ETH over Mul-E1
SNMP Managed Ethernet over 4/8/16E1 Converter,Support Point to Multi Point

1.Overview

 

FEOP Series is the IP over TDM converter, which supports the conversion from Ethernet to 1 – 16 E1 lines. The maximum bit rate is 31.68Mbps (16E1 lines). With different LAN card, E1 card and power card, it can meet various requirements. It not only provides alarms and status of the E1 line and Ethernet interface together with advanced management functions, such as, throughput statistic of the Ethernet, but also supports the Unification Network Management via SNMP and CLI commands.

 

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

 

2.Feature

 

Compact design with 1U height, 19 inch, 205mm depth, and can be installed on standard rack.

 

E1 interface

       ---> Provides 4, 8 or 16 E1 interfaces, compliant to G.703.

       ---> Data Rate of E1 interfaces:2.048Mbps; 

       --->  Line Code of E1 interfaces: HDB3.

       --->  Line Impedance of E1 interfaces: 120Ω balanced /75Ω unbalanced selectable.

       ---> Supports automatic removal and recovery of E1 channels that used for carrying payload, the E1

              channels that have urgent alarm, such as LOS and LOF or the the Bit Error Rate (BER) exceeds

           1E-6, are removed automatically; it will be resumed when the fault dismisses.

     ---> Supports the embedded E1 BER Tester function, to detect any E1 channel of 16 channels.

               In addition  to being tested E1 channel, the other E1 channels are not affected by the BER test

       --->  The differential delay between any two of the 16 E1 can be up to 220ms.

       ---> Jitter tolerance and jitter transfer characteristic compliant to ITU-T G.823.

 

Ethernet interface

      ---> Provides up to 4 Ethernet interfaces.

      --->  Port Combinations: 4built-in electrical (FE) or 3built-in electrical (FE) + 1 fiber optic (FX).

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

             The FX interface supports auto-negotiation, which can work in 100M full/half-duplex.

     ---> Connector of Ethernet interface

            RJ-45 for electrical (100BaseTx)

            FC or SC for optical (100BaseFx).

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

     ---> Compliance of Ethernet interface

            Optical Ethernet interface (FX) compliant to IEEE 802.3u 100BASE-FX standard.

            Electrical Ethernet interface (FE) compliant to IEEE 802.3u 100BASE-TX standard.

     ---> Max Frame Size: 1916 bytes; Min Frame Size 64 bytes.

     --->Supports port-based VLAN and IEEE 802.1Q tag-based VLAN.

     ---> Supports VLAN priority, and per port priority schemes enable users to define seven

            QoS levels  according  to application requirements. This concept provides high priority

             to real-time applications such as voice and video.

     ---> Throughout statistic of the Ethernet packets based on port, such as error packets.

     --->  Configurable pause flow control.

 

Timing mode

     ---> Optional local timing mode and tracing E1 line.

     ---> The source of tracing E1 line can be switched according to the signal quality.

 

NE Management

      ---> Supports CLI command based on RS232 port.

      ---> Supports CLI command based on Ethernet management (EMU) port (TELNET).

      ---> Supports Simple Network Management Protocol (SNMP), compatible with V1 and V2C protocol.

      ---> Monitoring the alarms and status in real-time.

 

Compliant to ITU-T standards

      ---> GFP-F encapsulation recommendation G.7041.

      --->  Virtual concatenation (VCAT) and Link Capacity Adjustment Scheme (LCAS) recommendation G.7042.

      ---> Ethernet to nxE1 mapping recommendation G.7043.

      ---> Ethernet to single E1 mapping recommendation G.8040.

 

Bandwidth is increased or decreased without damaging the Ethernet data.

 

The E1s in the local and remote sides can be arranged arbitrarily, such as, the remote E1 port 1 can

communicate with local E1 port 3.

 

Supports bandwidth unbalanced usage – when some E1s cannot work properly (i.e. the bandwidth 

of the sending and receiving can be 5E1 and 3E1 respectively).

 

Provides OAM-based E1 channel between local and remote system, the remote system can be

configured and monitored through the local system.

 

E1 tributary signal loopback automatic detect and cut off; when some E1 signal is detected as

looped back, it will be not employed for carrying payload temporarily, and when the loopback is broken,

this E1 will resume to be used.

 

Remote/local E1 loopback function will be convenient for E1 line testing.

 

Complete alarm which is selectable to be shown between local and remote.

 

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

---> DC 48(36-72) V Single power access.

---> DC 48(36-72) V Double power access.

---> AC 220(176-264) V single power access.

---> AC 220(176-264) V Double power access.

--->DC 48V (36-72) & AC 220(176-264) V Double power access.

 

 

3. Application

 

Figure 3-1 illustrates a typical application (point-to-point). With FEOP system, the Ethernet is transferred by 16E1. FEOP support OAM management frame-based E1 channel, by OAM frame, remote devices can be configured and monitored

 

 

As shown in Figure.3-2, with EoPDH and VLAN technology, the remote Ethernet service can be transmitted and converged into the service center (Switch) by FB002(point-to-multipoint); All devices support OAM management frame-based E1 channel, by OAM frame, all remote devices can be configured and monitored.
