XMC20 Multiservice Communication Portfolio
Full Hybrid Multi-service Access & Transport Platform for Communications Networks in Mission-Critical Systems
XMC20 is a purpose-built multi-service telecommunication family of network elements. It was designed to meet the stringent access & transport networks requirements for Mission-Critical Systems (MCS). XMC20 Mission-Critical Systems (MCS) address industries includes Oil and Gas, Rail and land transport, Air Traffic Management, Public safety, and Police-border control.
Being a full hybrid access and transport platform, the XMC20 supports the co-existence of native TDM and packet-based data transmission in one single network element. Thus, it is capable to fully evolve towards packet-based transport networks (MPLS-TP). With this, our customers have the flexibility to choose the best technology for their mission-critical applications. This lowers the operational costs and enhances the reliability and the availability of services.
The XMC20 provides the same scalability in TDM as well as in packet-based networks for highest availability under any circumstances. Comprehensive QoS functions (Quality of Service) guarantee reliable data transmission. German-produced XMC20 is equipped with numerous redundancy and protection functions for highly available data transmission. It is mechanically robust and can be operated in fanless mode due to its low power consumption and low number of components, providing a very good eco-footprint.
The XMC20 is unique in providing highly secure end-to-end encryption in mission-critical networks, while still maintaining the very high level of data availability required for such infrastructures. State-of-the-art encryption is based on keys generated by a hardware-based quantum random number generator for the highest level of assurance.
Services in XMC20 are administered centrally by the network management system UNEM and local craft terminal ECST. XMC20 can also be managed with the Ericsson ServiceOnAccess (SOA) network management system.

The subrack XMC25 offers 21 slots for cards. It is especially suitable for large access points which is to serve a large number of interfaces.
XMC23 offers the same functions as XMC25 in a more compact subrack of 4 height units.
XMC22 provides 4 slots in a 2-HU subrack for installations where space is very limited.
