Ethernet - Network Architecture

From the e|net Co-Location facility, the ring is lit at the appropriate level. Each Network Terminating Unit (NTU) will have diverse routing (east and west) to minimise disruption to any delivered service.

• NTU is VLAN aware switch from the e|net suite of products. Further information on equipment specifications is available upon request

• The customer is responsible for the provision of a clean protected power supply for the NTU (UPS etc.)

• The interconnect/demarcation point is the port on the front of the e|net NTU

• The customer is responsible for shaping the traffic in line with the purchased traffic profile

• Metro traffic with underlying SDH transport will utilise protection; Metro traffic with underlying Ethernet transport will utilise Rapid Spanning Tree Protection

• Delivery of circuits to DEG is based on one port being allocated to each carrier for interconnect purposes

• Any additional ports will be treated as separate drops and may be charged at additional levy
