Keymile XMC20

KEYMILE XMC20 IP Platforma koja podržava TDM i MPLS-TP

Hibridna platforma istovremeno podržava paketski prenos (IP, 1-10GbE, MPLS-TP) i TDM servise SDH(STM-1/STM-4/STM-16) i PDH do nivoa pojedinačnih kanala.

Za primenu u elektroprivredi važno je da su PDH servisi podržani do nivoa pojedinačnih kanala (n x 64kbps G.703, V.35/X.21, … sve do RS485) i to u okviru istog čvora koji na transportnom nivou podržava 1-10GbE i STM-1/4/16. To praktično znači da su PDH sistem i SDH sistem podržani u okviru jedinstvene platforme što donosi značajne direktne uštede u CAPEX-u i OPEX-u. Podrška MPLS-TP protokola i podržani kapaciteti ispunjavaju i uslove koji će u budućnosti biti zahtevani  u cilju primene Smart Power Grid rešenja.

Za primenu u drugim namenskim mrežama važna je fleksibilnost sistema i potpuna podrška savremenim voice i data servisima. Po pitanju bezbednosti XMC20 spada u sam vrh tehnoloških rešenja. Platforma nema ”back-door” i druge mehanizme koji kompromituju bezbednost.

Generalno, KEYMILE uredjaje karakteriše dug radni vek i visoka pouzdanost, kompatibilnost ”unazad” i podrška za nove, savremene servise.

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).

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. Equipped with numerous redundancy and protection functions, the German-produced XMC20 is also backdoor and spy free. It is mechanically robust and can be operated in fan-less mode due to its low power consumption and low number of components, providing a very good eco-footprint. In addition, it profits from the extended product-life-cycle of the KEYMILE products

All services in XMC20 are administered by a central network management system UNEM. The integrated management systems brings maximum synergy through managing all services on one platform. An easy-to-use local craft terminal (ECST) is as well available for our customers.

 

XMC20 platform highlights

  • Full hybrid concept for coexistence and inter-working of native TDM and packet services within the same node. Protection and redundancy functions for highly available data transmission Wide range of applications and access interfaces supported. Support for various transmission interfaces and protocols, including 10 Gbps, SDH STM-16, MPLS-TP and many others
  • Fan-less operation supported, robustness Guaranteed long life cycles due to state-of-the-art FPGA technologies and own manufacturing plant Wide array of services which include 3rd party equipment integration and maintenance All KEYMILE equipment and selected 3rd party equipment is managed under one Network Management System
 
The system family  
The sub-rack 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 sub-rack of 4 height units.
XMC22 provides 4 slots in a 2-HU sub-rack for installations where space is very limited.
 
CPEs  
LineRunner SHDSL DTM is a desktop for the connection to the SHDSL TDM-based line card SDSL8 with flexible subscriber interfaces.
