Ø Transparent transmission of Ethernet data in 1 to 16 E1 circuits;
Ø Can be equipped with four Ethernet switching electrical interface for the user to save an Ethernet switch;
Ø Ethernet 10 / 100M full / half duplex fully adaptive support VLAN protocol;
Ø Each port supports Ethernet support AUTO-MDIX (crossover cable and straight-line adaptation);
Ø Ethernet interface is also optional optical interfaces to achieve optical Ethernet data transmission through the interconnection E1 far;
Ø 16-channel E1 lines the maximum delay difference between any two can reach 220ms; when the delay difference over 220ms the delay will produce poor overrun alarm while business interruption;
Ø Built dynamic Ethernet MAC address list (4096) with local data fr
Ø E1 interface complies with ITU-T G.703 G.704 and G.823 do not support the use of signaling slots;
Ø Timer mode the optional local timing and tracking E1 line timing E1 line timing source can be automatically switched according to the signal quality. Such as E1 line timing source system for the first Road E1 when the first E1 failure (serious warning LOS / AIS / LOF / CRC4 or signal generating loopback) and the second path E1 is working properly the system will automatically switch to the track The second road E1; elimination of the fault the system then automatically return to the track first road E1;
Ø Compliance with ITU-T standard protocol GFP-F encapsulation suggestion G.7041 VCAT virtual concatenation and LCAS Link Capacity Adjustment recommendation G.7042 Ethernet mapping to nxE1 recommendation G.7043 Ethernet to single E1 map suggestion G. 8040;
Ø When transmission bandwidth increases will not damage the Ethernet data; transmission bandwidth is artificially reduced it can also be realized without damaging the Ethernet data network;
Ø E1 tributary ? ends may not correspond by serial connection;
Ø When a single slip direction E1 fails the other direction can still work;
Ø E1 signal loop back and cut off the automatic detection function: When detecting the occurrence of a road E1 signal loop the system cut off this E1; loopback released E1 automatic recovery use this road;
Ø Complete alarm indication choose to display local / remote alarm;
Ø Supports remote E1 line side loopback function to facilitate the testing of E1 lines;
Ø Support local system for the remote system reset;
Ø provide remote interface loopback command easy to line maintenance;
Ø Console management interface provides for easy installation opening;
Ø Configuration network management module support independent SNMP network management;
Ø with this end in view the working status of remote device display function;
Ø Multiple power mode options: AC220V DC-48V / DC24V and the like;
Ø DC-48V / DC24V power supply with automatic polarity detection function when installed without distinction between positive and negative.
