Ethernet

 

Pantel’s Ethernet service targets communications needs of transparent Ethernet transmission with constant access rate and extremely low jitter. Ethernet service is fully transparent to customer traffic and provides point-to-point or point-to-aggregate transmission between service access point at customer premises and interconnection point to Bloomberg.

 

Core network is non-contended and built on SDH and MPLS infrastructure thus each connection has reserved and 100% dedicated bandwidth. Availability of core network is 99,99%.

 

Local tails use non-contended access: dedicated fiber, SDH, licensed band point-to-point microwave, copper leased line. Each connection has dedicated and reserved bandwidth. Local tails may be protected on request. Local access is available with CPE by default provided by Pantel. Unbundled service – without CPE – is also available on request. CPE type is preferably Cisco ME3400 or equivalent.

 

The Ethernet service is point-to-point and fully transparent. Service handover options:

  • Each circuit is handed over via standalone physical interfaces at both endpoints.
  • Optionally E-NNI interconnection is available with Cisco QinQ.

One-by-one service handover presents all Ethernet private lines on separate interfaces. Aggregated hand-over is also available.

 

On customer interfaces both tagged and untagged frames are accepted and transmitted unchanged up to the MTU relevant to the circuit. The transparent Ethernet service is presented on networking devices that are not aware of L2CPs from customer sites.  Transmission is free from reordering.

 

Following protocols are transmitted transparently by default: STP, RSTP, CDP , Cisco VTP.

 

The transparent Ethernet service does not introduce use of service classes and packet reordering. Bursting above committed bandwidth is not supported due to the nature of underlying technology.

Transmission performance (i.e. throughput) is not affected by frame size.

Bandwidth Profiles

 

Circuit speed is always interpreted as Ethernet L1 that includes all higher layer data, inter.frame gap, SFD and preamble.

 

Fibre, SDH and PP microwave local tails are available with circuit speeds of:

  • 10M interface: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 Mbps
  • 100M interface: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 Mbps
  • 1G interface: 100, 150, 200, 250, 300, 350, 400, 450, 500, 600, 700, 800, 900, 1000 Mbps
  • 10G interface: from 3 Gbps to 10 Gbps

Interface Options

 

Optical interfaces

  • 1000BaseSX, 1000BaseLX
  • Connector types: LC, SC

Electrical interfaces

  • 10BaseT
  • 100BaseTX
  • Connector type: RJ45


Point-to-Point Service Options (port-based handover):

GigabitEthernet interface is available for access speed above 100Mbps only. Ports are set to auto-negotiation by default.

Pantel’s Ethernet service is presented preferably via same interfaces on endpoints.

 

Point-to-aggregate Service Options:

GigabitEthernet interface on customer premises is available for access speed above 100Mbps only. Ports are set to auto-negotiation by default.

Aggregate interface (E-NNI) is planned as GigabitEthernet:

  • 1000BaseLX (proposed);
  • conforming IEEE 802.1ad (Ethertype is 0x9100)
