Direct Fibre Access
For service connectivity up to 10Gbit, Direct Fibre Access is provisioned with Vtesse provided private Dark Fibre.
EFM (Bonded Copper) Access
"Ethernet First Mile" access provides a effective alternative to many fibre based 10 and 100Mbit services.
EFM services are provisioned to customer premises using multiple pairs of copper circuits. These "bonded" copper circuits provide Ethernet connectivity from 2Mbit up to a maximum of 40Mbit.
National Ethernet Service
ETHER/LIGHT
Vtesse ETHER/LIGHT is a secure, private, managed Virtual LAN service designed to provide Ethernet connectivity between Local Area Networks in geographically dispersed customer premises. ETHER/LIGHT uses Vtesse's own UK national fibre network ensuring the highest levels of service availability, support and integrity. Fibre optic and copper circuits are used to deliver service to customer sites at speeds from 2Mbit to 10Gbit.
Service Overview
ETHER/LIGHT is a 4th generation Ethernet multi-site connectivity service. ETHER/LIGHT leapfrogs the complexity and overheads of 2nd generation MPLS services in favour of the simplicity and efficiency of "pure Ethernet". Furthermore, by implementing ETHER/LIGHT directly on the Optical Network Layer, we reduce network overhead which in turn improves performance (lower latency and jitter), lowers cost and increases service availability.
Services are designed to be compatible with Metro Ethernet Forum (MEF) standards and include definitions for Point to Point, Point to Multipoint and Any to Any services.
ETHER/LIGHT supports a broad range of connectivity options, including private fibre, LAN Extension and EFM ("Ethernet First Mile" over copper) services making cost effective service available to a wide range of site sizes and requirements.
Ethernet Virtual LANs (VLANs)
Secure connectivity between sites is enabled through the use of Ethernet VLANs.
By supporting QinQ technology and by preserving customer VLAN tags, each site may be a member of multiple VLANS, enabling multiple, secure, communities of interest to be defined between customer sites, by each customer.
Bandwidth at each customer site is scalable up to the maximum speed of that site's access circuit enabling rapid changes to be made to accommodate changing customer needs.
ETHER/LIGHT private line services provide Circuit Emulation functionality, enabling cost effective emulation of SDH E1 circuits, eliminating the need for existing inter-site E1 private circuits.
Service Protection
Services are protected from physical failure of network equipment and routes by using fast re-routing (sub 50 milliseconds) technology making ETHER/LIGHT a suitable transport for voice, video and data applications.
Standard Classes of Service (CoS)
4 standard QoS profiles are defined. All employ traffic prioritisation mechanisms to ensure that in the event of contention, key applications receive the prioritisation they need. ETHER/LIGHT QoS classes may be mapped directly to customer's IP Classes of Service, facilitating predictable application performance at all levels of the Enterprise.

LAN Extension Service Access
LES access allows transparent delivery of all Vtesse ETHER/LIGHT service types and QoS classes at speeds from 10Mbit up to 1Gbit per site.
