Description

YG480E is a 4(8) E1 inverse multiplexer capable of transporting high speed data [LAN], MPEG-2 or new broadband services over 1 to 4(8) E1 links. YG480E uses a proprietary E1 frame based aligning method to split broadband data into 1 to 4(8) E1 links for transporting over PDH/SDH network. At a remote peer, the 1~4(8) E1 links can be identified and aligned sequentially to recover inversely to the original broadband data with limited delay among the E1 links.

YG480E is equipped with LAN interface for broadband data services. The bandwidth of YG480E transport is scalable as Nx1.984Mbps [N=1~4(8)]. The maximum payload bandwidth of YG480E is 8 Mbps [7.936Mbps] or 16 Mbps [15.872Mbps].

YG480E is supported by a set of local and remote Operation, Administration, Maintenance and Provisioning (OAM&P) facilities. These facilities include SNMP LAN interface, Telnet, RS-232C craft interface (CID) and TopView. TopView Graphical User Interface(GUI) offers a user-friendly and easily adaptable interface with a variety of configuration, management and maintenance options.

The remote configuration and OAM&P are achieved through YG480E's 12Kbps embedded operational channel (EOC). To facilitate various application environments, YG480E has a 19-inch wide, 1U height standalone unit as well as a 19-inch wide, 7U height shelf. A central management card housed in the shelf can be used for controlling up to 14 line cards simultaneously.
