We are offering ethernet converter humanity hm-c200b 4e1 to ethernet converter realizes ethernet transmission over 1~4e1. This model complies with itu-t g.7041, g.7042, g.7043, g.8040 and able to work with third party device followed same protocol. main feature realize ethernet data transmission over 1~4e1 comply with itu-t g.7041, g.7042, g.7043, g.8040. It’s able to work with third party device followed same standard itu protocol. Support auto delete the fault e1 channels (ber more than 1e-6 or a serious warning los/ais/lof or the signal loop back); auto-restore the use of e1 after eliminate the failure. The e1 spur track on both ends can be connected not according to the serial number. If one e1 channel fails, the rest channels can still work. for 4e1 channels, the maximum tolerable time delay difference between any two can be up to 220ms. technical parameters e1 interface 4*e1 code rate: 2048kbps±50ppm connector: bnc for 75ω and rj45 for 120ω line code: hdb3 electric characteristic: comply with itu-t g.703 standard jitter index: comply with itu-t g.823 standard ethernet interface 4 ethernet interface connector: rj45 fully comply with ieee802.3 4 ethernet interfaces with vlan, comply with ieee802.1q auto adapt mdi/mdix data rate: 10/100mbps auto-negotiation mac address table capability: 1024 minimum frame length: 64bytes maximum frame length: 1916bytes bandwidth: ≈n×e1（n=0～4） default setting: 4×e1 ≈7.92mbps network management rs232 hyper terminal or snmp optional alarm indicator link1~4: 1~4 channel ethernet indicator light alr: general indicator light l01-l04: e1 spur track alarm indicator for different status local/remote: local or remote alarm option switch alarm/mask: alarm/mask choice switch dip sel switch sel1~sel2: control l01~l04 indicator contents sel3: loop back control switch sel4: vlan control switch power supply voltage: ac and dc power consumption: less than 10w environment work temperature: -5°c~50°c storage temperature: -40~70°c relative humidity: ≤95％, non-condensing

We are offering ethernet converter humanity eop hm-c800b 8e1 to ethernet converter realizes ethernet transmission over 1~8e1. This model adopts with new international protocol (g.7041、g.7042、g.7043、g.8040) at all layers and able to intercommunicate with third party device followed same standard. main feature support auto delete the fault e1 channels (ber more than 1e-6 or a serious warning los/ais/lof or the signal loop back); auto-restore the use of e1 after eliminate the failure. For 8e1 channels, the maximum tolerable time delay difference between any two can be up to 220ms. It will have an alarm for exceed the limit when the time delay difference over 220ms, meanwhile, business interrupt jitter tolerance, jitter transfer characteristics in the line with itu-t g.823. e1 automatic test loop back and cut off function. The e1 channel will be cut off once find e1 signal loop back. Auto-restore the use of e1 after release. Avoid the network storm without interrupting operations. Support local e1 channel loop, facilitate to test e1 channels ethernet data will not be damaged if enlarge or reduce the transmission bandwidth by means of network management. technical parameters e1 interface e1: 8 e1 channel according to itu-t g.703 velocity: 2.048mbit/s ± 50ppm impedance: 75ω unbalanced or 120ω balanced optional jitter index: comply with itu-tg.823 standard connector: bnc or rj45 optional. Db37 with device and able to be with 8 rj45(120ω) or 16 bnc(75ω) by 2pcs adaptor. ethernet interface 4 ethernet with vlan connector: rj-45 vlan control by dip sel4 switch according to ieee 802.3 recommendation comply with ieee802.1q auto adapt 10/100m, full/half duplex auto support flow control(back press control in half duplex and pause flow control in full duplex) mac address table capability: 1024 mac address table aging time: 5 minutes minimum frame length: 64 bytes maximum frame length: 1916 bytes indicator light alarm/remote: indicator lights for local or remote option alarm/mask: whether the alarm will be masked option power1 and power2: power indicator light for ac and dc link1~4: for 1~4 ethernet connection status alr: general alarm.
