XMP1-LCC
XMP1-LCC - Highest cross-connect capacity in a compact housing
The XMP1-LCC is a modular, compact Next-Generation multiplexer. It can be fitted with 2 Mbps, Ethernet and SDH interface cards. STM-1/STM-4 (optical and electrical) or STM16 (optical) interfaces are available for SDH connection.
Its efficient cross-connect allows separate switching at 64 kbps/2 Mbps and SDH level. The cross-connect capacity enables separate switching of up to 252 x E1 at 64 kbps and up to 48 STM-1 signals at SDH level (VC-12/3/4).
For Ethernet data, the XMP1-LCC offers Fast Ethernet and GbE interfaces whose data is transmitted with EoS functions (Ethernet over SDH) via the SDH network. The Ethernet packets are controlled and switched via a layer 2 switch. The layer 2 switch supports VLAN, Quality-of-Service functions (QoS) and the rapid spanning tree protocol. As a result, the XMP1-LCC is ideal as an access multiplexer in the SDH backbone.
Thanks to its vast cross-connect capacity and high number interfaces, it consolidates incoming PDH and Ethernet data for forwarding to the SDH backbone network. The central units can be installed redundantly. Then the XMP1-LCC will have a high level of availability and can be used in mission-critical applications. The XMP1-LCC belongs to the XMP1 family and supports the protection functions and operation modes of the XMP1 multi-service access multiplexer.
The network management system SOX (Service on XMP1) allows the whole XMP1 network, including XMP1-LCC, to be fully configured and monitored in a user-friendly manner. SOX provides additional protection functions that increase the availability of the network even further. Typical public transport and railway company applications are: E1 and Ethernet access multiplexers in the SDH backbone.
