Description
480EC Ethernet over SDH/PDH aggregation gateway
480EC is Ethernet over SDH/PDH aggregation gateway that combines Ethernet traffic carried over SDH/PDH into an Ethernet MAN (Metropolitan Area Network). 480EC can aggregate up to remote LANs over fractional E1 inverse multiplexer 416EL, 408EL, 404EL & 401EL using standard bonding protocols.
480EC is a The unit features next-generation Ethernet over SDH/PDH encapsulation and bonding capabilities with support for standard protocols such as generic framing procedure (GFP),. The GFP protocols allow service providers to dynamically allocate bandwidth to their customers. Ethernet port supports 802.1q VLAN, 802.1p QoS & Q-in-Q layer 2 switching features. The dual STM-1 ports support redundancy operation.
480EC can be managed locally by connecting a VT-100 emulated PC to the CID port or remotely through Telnet/SNMP access all on front panel of the unit. Administration, Maintenance, and Provisioning (OAM&P) are provisioned with the use of 16Kbps embedded operation channel (EOC) that runs through the inverse link. Configured with individual IP address for local and remote unit,480EC is accessible to the Internet users who are managing the units from a far end place.
To ensure operation continuity and accommodate field requirement, 480EC offers choices of AC or DC or AC+ DC power.
408EC
