Bộ chuyển đổi 4 cổng E1 sang 4 cổng Ethernet JHA Tech JHA-CE4F4

4E1 (75ohm/120 ohm) to Ethernet interface converter adopts reverse multiplexing technology, bundles multiple E1 circuits for transmitting 10/100M Ethernet data, realizes the interconversion from 1-4 channel E1 channel to Ethernet interface, and realizes the interconnection between E1 channel and Ethernet. The Ethernet package uses the GFP package and supports the LCAS and LAPS protocols.

The device supports 1~4 dual impedance E1 interface (75 ohm + 120 ohm); the flexible configuration of the channel can automatically detect the number of E1 and select the available E1, and allows a certain transmission delay difference between E1 circuits. The single-route rate is 1984 Kbit/s, and the 4-route bandwidth can reach 7936 Kbit/s.

With perfect alarm function, the whole machine is stable and reliable, low power consumption, high integration, small volume. Also has the network management module, support the single machine independent SNMP network management. It is suitable for LAN interconnection, local interconnection, video on demand, remote monitoring, switch E1 interface card insertion and other fields.

Tính năng

• Based on self -copyright IC
• To achieve Ethernet data transparent transmission in 1-4E1 circuits
• Can realize the local and the remote device reset
• Ethernet Interface is 100BASE-FX, support VLAN protocol
• Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering function
• Single Channel lines rate is 1984Kbit/s, 4Channel Bandwidth is up to 7936Kbit/s
• Channel 10M/100M Ethernet interface can isolate each other to realize communication independently
• Ethernet interface supports10M/100M, half/full duplex auto- adaptable and AUTO-MDIX  (crossed line and straightly connected line self-adaptable )
• CRC automatic alarm threshold can be set to isolate the poor quality transmission lines and cut off a single-direction. When 2M branch circuit onedirection error rate exceeds threshold, cutting off this direction the other direction is not affected; that is to say, both of the Ethernet directiontransmission can be asymmetric
• Allow 4-Channel E1 transmission time delay difference 100ms. When the margin exceed the allowed range, the system can automatically stop on the E1 that time delay is too large to send data
• E1 interface conform to ITU-T G.703, G.704 and G.823, not support the use of signal timeslot
• E1 interface module with inter-set clock recovery circuit and HDB3 code circuit
• Support E1 channel hot-plug in the device, and automatically detects the effective E1 channel and will not interrupt data transmission
• Can support 1-4Channel E1 channel configuration, can automatically detect the number of E1 and select the E1 available;
