Wavestream Regional 2.5Gbit/s and 10Gbit/s

A wavelength service provides point to point, chain, or ring connectivity at 2.5Gbit/s and 10Gbit/s per wavelength, between two customer sites separated by a distance of up to 70km. Wavestream Regional is a data service allowing the transport of a variety of protocols such as STM-16, FICON and Gigabit Ethernet.

Wavestream Regional offers one initial active wavelength operating at 2.5Gbit/s or 10Gbit/s. Customers may, if and when they wish, upgrade the service to a maximum of 32 active wavelengths, per system (subject to survey).

Provision of Service

Product Description

Wavestream Regional is a point-to-point data service offering high bandwidth service connectivity between customer sites, provided over dedicated optical fibres. It uses Dense Wave Division Multiplex (DWDM) technology. Dense Wave Multiplexing allows one pair of fibres to be split into 32 wavelengths, each capable of reaching up to 2.5 Gbit/s and 10Gbit/s. The systems can support a mixture of up to 32 wavelengths of 2.5 Gbit/s and 10 Gbit/s depending on fibre characteristics and overall route length.

Each wavelength can support a different protocol and carry separate data. Wavestream Regional allows the Customer to send a combination of different protocols over one pair of fibres simultaneously.

Wavestream Regional is suitable for linking BT serving exchanges up to 70 Km radial.

There are three variants of the Wavestream Regional product - Wavestream Regional A (RO1), Wavestream Regional B (STD) and Wavestream Regional dual B (RO2). The Wavestream Regional A has two transmission paths and is provided on an assured basis. The Wavestream Regional B is a single transmission path.

The Network Terminating Equipment (NTE), connected to the ends of these fibres, provides the interface appropriate to customer requirements and the service being provided.

The Wavestream Regional service is offered in three distinct topologies. Each of these topologies is described below.

Point to Point

The Wavestream Regional service is set up between two customer sites using dedicated fibre routes. Depending on the fibre route distance amplification may be required (mid-point and/or end-point).

NTE is provided at each end of the point to point service.

Wavelength switching protection is also available for Point to Point Wavestream Regional A.

Chain

In this configuration a number of Wavestream Regional wavelengths are connected together to form a chain.

A maximum of 25 Wavestream Regional wavelengths can be linked into a chain. A Wavestream Regional wavelength consists of a number of NTEs grouped into a single logical entity. Each Wavestream Regional wavelength can be included in only one chain.

Wavelengths can be ordered between any two sites on a chain.

Wavestream Regional A is not available with the chain topology.

Wavelength switching protection is not available on a chain configuration.

The first Wavestream Regional wavelength in the chain is delivered with the fibre route and an NTE with optical filters at each end. Each subsequent Wavestream Regional wavelength in the chain is delivered with the fibre route, optical filters at each end and an NTE at one end only.

Ring

In this configuration a minimum of 3 and a maximum of 16 Wavestream Regional wavelengths can be interconnected to form a ring. A Wavestream Regional wavelength consists of a number of NTEs grouped into a single logical entity. Each Wavestream Regional wavelength node can be included in only one ring.

Wavelengths can be ordered between any two nodes on a ring. In addition each wavelength can be specified to be routed in either direction around the ring.

Wavestream Regional A is not available with a ring topology.

Wavelength switching protection is available so that the signal can be transported in the opposite direction around the ring in the event of a failure to arrive at its destination.

Each Wavestream Regional wavelength in the ring is delivered with one NTE, the fibre route and optical filters at each end.

Eligibility

Wavestream Regional is available nationally within the UK to all customers requiring 2.5Gbit/s and 10Gbit/s services for a minimum of 12 months contract period.

The Customers should note that Wavestream Regional services may not to be used to build, extend or replicate a core network. If such usage occurs BT may take appropriate action under the applicable Contract. Such action may include suspension and/or termination of the service(s).

All Contract Types: Terms and Conditions

Service is provided under BT's "Conditions for Private Services".

All Contract Types:

1. Termination

i) Either Party may terminate any individual Service by giving not less than 30 days written notice to the other subject to payment by the Customer to BT of any outstanding charges and any applicable termination charges as set forth in this Price List.

ii) If BT gives notice, the Customer must pay rental up to the expiry of the notice. If the Customer gives notice after the Minimum Period, the Customer must pay rental until expiry of the notice, whichever is later. If the Customer gives notice within the Minimum Period the Customer must pay rental or other charges for the remainder of any Minimum Period at the rate in force at termination or as otherwise provided in the Price List.

2. Early Termination

Where the Customer terminates the contract before the Minimum Period has expired, then, in addition to all outstanding connection charges for Service rendered, the Customer will pay the termination charges below:

(a) an amount equal to the rental and other charges for any remaining months of the first 12 months of the Minimum Period;

(b) an amount equal to 20% of the rental and other charges for all other remaining months of the Minimum Period

3. Completion of the Contract Term

Unless the Customer has chosen to either renew the existing contract or has signed a new contract with BT, charges shall remain the same upon expiration of the contract term.

4. Cancellation Charges

Cancellation charges will apply, as described below.
