CEM

Transparent Ethernet connection between company branches and headquarters

Benefits CEM

CEM is the optimal option for end customers who require a premium Ethernet connection between a branch’s network and their headquarters, guaranteeing high transparency (VLAN, L2/L3 protocols or high MTU) and availability (SLA). Carrier Ethernet Multi allows you to create an Ethernet network terminated at company headquarters (point-to-multipoint topology) with guaranteed symmetric connection from 2 Mb/s to 5 Gb/s.

  • Geographical flexibility in terms of the location of end sites and headquarters
  • Support for L2/L3 protocols and VLAN transparency
  • Possibility of different connection (metallic, fibre optic, licensed radio) for each branch
  • Point-to-multipoint topology
  • Guaranteed maintenance service and service availability through SLA
