EOS

System Cabinet
 Height :1U; Width : **0mm; Length : **5mm
 Supports TU**2 Granularity Cross Connection.

Optical Interfaces
 Two STM*1 optical interfaces; SFP optical module (LC interface); Hot plugging.
 Supports only single mode fiber. Transmitting distance :*5km (by default), *0km, and *0km.
 Complies with GB/T*********5 and ITU-T G.**3 standards.
 Supports RPD (Remote Power-Down Detection); transmits local power-off message.
 Supports ALS (Automatic Leaser Shutdown) to protect operators from hurt.

E1 Interfaces
 Provides an E1 I/F card slot, *-E1 or *-E1 I/F card are selectable.
 **0Ω balanced / *5Ω unbalanced E1 interfaces(RJ*5 / DB*7 connector) are selectable.
 E1 interface complies with ITU-T G.**3 standard.

ETH Interfaces
 4 LAN ports(physical interfaces). Each supports self-negotiation. *0M/**0M; Half-/Full-duplex.
 4 internal WAN ports, each corresponds to a VCG which has a bandwidth of up to *8 VC*2 (**0Mbps). At most  *3 VC*2 can be configured to the entire bandwidth of the 4 VCGs.
 4 LAN ports and 4 WAN ports comply with
 IEEE**2.3/**2.3u standard, support frames of **2.3 format and Ethernet II.
 Supports traffic control and the filtering function for the broadcast storms.
 Supports port-based VLAN and tag-based VLAN that comply with IEEE **2.1Q standard.
 Supports GFP-F encapsulation; complies with ITU-TG.***1 standard.
 Supports VCAT and LCAS; complies with ITU-T G.**7, G.***2 standards.
 Provides VC*2 time-delay detection. The maximum tolerable differential delay between any of two VC**2   channels is **2ms.
 Provides both LCAS and non-LCAS modes

 Supports DCC and embedded DCN modes of network management.
 Supports CLI management based on serial port and TELNET. CLI supports only the control over the local  equipment and can not manipulate other NEs in the network.
 Supports SNMP_V1 and SNMP_V2 protocols; supports PC-based, C/S mode of network mana- gement platform**- NETVIEW, to implement the configuration, control and maintenance.
 One **8V DC, or one ~**0V AC power supply; power consumption is less than *5W
