VLAN function: Disabled as default, you can set VLAN’s from GUIīandwidth: ≈n×E1 （n=0 ～4 ）Default is 4 ×E1 ≈8.19Mbpsĭimension: 434mm×44mm×155mm （width× height× depth ） Working mode: Support auto-negotiation compliant to IEEE802.3u.

Jitter transfer, Jitter tolerance comply with ITU-T G.703 、G.704 、G.823 recommendations Impedance: 75 Ohm is default, Optional 120 Ohm Working mode: Auto – negotiation is the default settingĬomplies with IEEE 802.3 and 10/100 Base-Tx Ethernet Protocol

Single-board design with small dimension, 1U high and low power consumption.

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

Remote/local E1 loopback function will be convenient for E1 line(transmission system included) testing.

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.

Provides the E1 connection-ship between local and remote system (accessed via GUI).

the bandwidth of the sending and receiving can be 2E1 and 3E1 respectively ). Supports bandwidth unbalanced usage – when some E1s cannot work properly (i.e.Bandwidth is increased without damaging the Ethernet data, and can be decreased no injury through management Į1s in the local and remote sides can be arranged arbitrarily, such as, the remote E1 port 1 can communicate with local E1 port.Ethernet to single E1 mapping recommendation G.8040.Ethernet to n圎1 mapping recommendation G.7043.Virtual concatenation(VCAT) and Link Capacity Adjustment Scheme (LCAS) recommendation G.7042.GFP-F encapsulation recommendation G.7041.

1024 MAC address table and 5-minute aging time.

Provides up to 4 shared Ethernet interfaces.

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

The differential delay between any two of the 8 E1 can be up to 220ms when the factual differential delay exceeds 220ms, alarm is generated and Ethernet is cut off.

When the embedded E1 BER Tester is used via CLI command, the particular E1 channel on testing mode can not convey E1 service, while the other E1 channels are not affected by the BER test

Supports the embedded E1 BER Tester function, to detect any E1 channel of 8 channels.

The E1 channels that have urgent alarm, such as LOS and LOF, or the Bit Error Rate (BER) exceeds 1E-6, are removed automatically, and during this period, some Ethernet packets may be lost It will be resumed when the fault dismisses

Supports automatic removal and recovery of E1 channels that used for carrying payload.
