3. Service Description

3.1 Technology

Colt Wave services provide high-capacity, point-to-point Layer 1 transparent optical data services between two locations. They are available on a Metro, National or International basis. Bandwidths of 1G, 2G, 4G, 8G, 10G, 16G, 32G, 100G and 400G are provided, using industry-standard presentation/interfaces and connector types.
Optical technologies are used in conjunction with OTN, Mux/Demux or muxponder equipment. They provide deterministic performance and are fully transparent to higher level OSI Layer 2, Layer 3 and above protocols. Latency is not subject to variation and is determined largely by the fibre distance between the two end-points. Frame loss/bit error rates and jitter are at the lowest possible technical levels, as befitting an optical multiplexed network.
Wave Services are based on an optical DWDM (Dense Wave Division Multiplexing) core network. In the specific cases of the transatlantic, trans-Pacific, the North America and International Asia networks, leased OTU4 capacity is used in conjunction with Colt’s own optical equipment.In cases where DWDM equipment is not already installed in the required service location, the local connection from Colt’s optical service point to the customer site may be made via a fibre extension within the metro area. In order to provide services over longer metropolitan distances from designated service points and deal with higher signal losses, clear channel optical equipment or CWDM may also be used in the ‘last mile’. Optical Ethernet equipment using customer-dedicated fibre and electronics is also available in the specific case of 1G Ethernet and 10G LAN PHY services.
The precise deployment, along with network route details and other relevant technical information will be determined during the Sales and Pre-Sales process.
Services can be provided on an unprotected (single fibre path) or protected (dual path) basis. Additional resilience features include the option for a customer-defined route, whereby the customer can stipulate the network route for an individual service and full service diversity between a pair of unprotected services.
Colt is able to provide services up to 400G across its entire terrestrial optical footprint, including European sub-sea routes, regardless of the specific optical platform available in a given city location.

3.2 Topology

Colt Wave services are point-to-point services.

3.3 Platforms

3.3.1 General

In some cases, the customer requirement may mandate the use of a specific technology platform. Flagship 10G LAN PHY, 100G Ethernet and 400G Ethernet services will be provisioned on the Optical Express network (see below) by default where it is available.

3.3.2 Intercity Optical Express Network

A state-of-the-art network based on Ciena/Nokia technology, referred to as the Intercity Optical Express Network, spans 42 cities and 30+ countries, with integrated metro optical networks in 20 cities. Metro optical networks are seamlessly integrated with the long-distance network using this common platform. With 20Tb+ of capacity, it directly connects key service locations such as data centres across the Metro, National and International areas in Europe and Asia’s key markets.
Bandwidth is configured in 100G up to 800G coherent channels, thus enabling the rapid and easy provisioning of large amounts of capacity with improved levels of service availability and faster delivery times.

3.3.3 Sub-Sea and North American Leased Capacity Networks

This optical network uses leased 100G OTU4 capacity between Europe and the USA (the transatlantic network), between countries within Asia (the Asia international network) and between Asia and North America (the trans-Pacific network). Leased capacity is integrated with Colt’s own DWDM equipment to provide optical services globally at 1G and 10G.
Colt’s fibre optic network links within Europe between Ireland, the United Kingdom, Scandinavia and mainland Europe are a part of the European terrestrial network and not part of the sub-sea network.

3.4 Bandwidth & Interface Options

Colt Wave Services provide fully dedicated bandwidth and are full-duplex, protocol- independent services, which means customers can use the full amount of the bandwidth supplied in either direction.
Those 10G, 100G and 400G services delivered on Ethernet interfaces are compliant with the IEEE 802.3-2015 MDI specification (Medium Dependant Interface), as defined in the UNI specification. In the case of Ethernet presentations, auto-negotiation must be enabled according to IEEE 802.3-2015. In the case of non-Ethernet presentations, the bandwidth and full duplex mode operation are defined in the relevant ITU standard.
Colt Wave Services support a wide range of optical bandwidths and interface standards. A sub-set of the standard Wave options are offered on the part of the optical network built using leased capacity. The available bandwidths are:

Bandwidth	Signal Type	Colt Europe Metro National International	Colt Asia Metro National	Colt Asia International	Asia – USA Europe USA National1

Table 2. Wave interface options

1 – Multi-fibre parallel optics must be used
2 – Not available with extended fibre ‘last mile’ delivery

In large and structured environments such as data centres, the required presentation may be conditioned by factors beyond Colt’s direct control, such as the distance between the Colt terminating equipment and customer equipment and the specification of intermediate ‘meet me’ cross-connect cabling facilities.

MPO/MTP	Europe

Table 5. Interface Options

Please Note! The availability of a specific connector type in a given building may be affected by a number of factors:

Data Centres and other Structured Building Environments

In structured environments such as data centres, a cross-connect is normally required between either Colt’s equipment area or the ‘meet-me’ interconnection facility and the customer end-point. In cases where the customer is responsible for obtaining this cross- connect, it is also the customer’s responsibility to request the correct connector type for their own end-point within the context of any policy or infrastructure constraints imposed by the building operator or the built infrastructure environment.
In cases where Colt orders the necessary cross-connect on the customer’s behalf, the selected connector will reflect that required at the customer end-point of the cross-connect and not Colt’s terminating equipment in its own facilities or meet-me room presentation point. Connector availability may be constrained by policy standards dictated by the third-party data centre provider that controls the ‘meet-me’ interconnection room environment and provisioning of in-building cross-connects.

Enterprise Sites

In enterprise sites Colt may provide its services from a common equipment area (CEA) to the requested location using pre-provisioned structured internal cabling to a Colt patch panel within either a Colt or customer rack. Colt normally adopts the LC connector type in these installations. A customer that requires a different connector type from that supported by the fixed infrastructure should use suitable fibre-optic fly leads to effect the necessary conversion between the Colt patch panel presentation and their own equipment.

3.10 Resilience Options

3.10.1 Architecture

Colt’s optical platforms are built to a redundant and diverse design, thus ensuring that a wide range of resilience options are available to customers in order to support their business continuity requirements.
Colt optical PoPs are usually built using a dual-chassis approach with each PoP being served by at least two separate fibre routes. The ‘East’ and ‘West’ directions terminate in separate chassis so that failure of an individual chassis does not lead to failure of diversely routed services.

Strategic Colt cities may have several geographically separate nodes, each with its own redundant architecture. This enables services to be routed diversely from one city to another using separate city PoPs.
Depending on the location, area and circuit speed, Colt Wave services can be provided as Unprotected, Backbone Protected or Protected.

3.10.2 Circuit Resilience Options

Unprotected – an Unprotected service is a single circuit with a single client interface and single worker path across the network.
Protected – a protected service is a single circuit with a single client interface, but has a fibre protection path in addition to the main worker path. Automatic failover between fibre paths provides protection switching as well as automatic restoration once the worker path is available again. A protected service does not absolutely guarantee the absence of other single points of failure (SPOFs) in the terminating PoP or site. The level of separacy of the worker and protection fibre paths can be confirmed to the customer with a KMZ network route diagram.
Backbone Protected – the service is protected in the ‘core’ network but remains unprotected in the ‘last mile’ metro access. This feature is only available as standard in Asia for services up to 10G and is subject to bespoke approval in Europe.

3.10.3 Diversity

The Diversity feature always refers to the provision of two services in a diverse configuration from one another, with each service following a designated network route across the optical network. The diversity feature is always supported by a KMZ route diagram which confirms the agreed routing of the two services.
Colt offers diversity solutions in two ways – a standard service offering on the IQ Network or via a design-led approach.

3.10.3.1 Standard Diversity Offer

The standard offer has a defined service specification, scope and list pricing. It is available only between sites directly connected to the optical IQ Network. In this offer, the network routes proposed will be the default primary and alternate IQ Network paths between the requested end-points. These can be provided by Colt for confirmation and acceptance with the customer. A customer that orders two diverse services based on the standard offer is therefore accepting the routing of these pre-built network paths as demonstrated by the Colt- provided KMZ route maps in the proposal. Although these routes are largely diverse, the customer is explicitly accepting any exceptional cross-overs or SPOFs that may exist in the default routes between their chosen A and B-Ends.
The service specification for the standard diversity offer is shown in the table below:

Feature	Description
Scope	IQ Net Data Centres (directly equipped with WDM equipment)
Number of circuits	2 x Wave (Each ordered as separate individual circuits)
Redundant Termination	Redundant service termination using dual WDM chassis, dual WSS, dual ROADM node
Fibre Path Diversity	Fibre path diversity as per KMZ tool output – IQ Net default primary and alternate paths
Coverage	Metro, National, International – Europe
Optical Presentations	All standard Wave service types (Ethernet, OTU etc.) supported
KMZ Route Map	Yes – mandatory – as per KMZ output of the RTD Tool
Building Entry Points	Site dependent – single or dual entry depending on build of the IQ Network
PoP Power Configuration	Redundant and Protected
Rack/Room	Single rack / single room in data centre PoP
Service Level Agreement	The standard SLA for each applicable service in the pair applies

Table 7. Diversity Standard Offer – Description

It should also be noted that the standard offer exploits the building entry points and internal building cabling systems inherent to the IQ Net platform that defines the offer scope. It does NOT mandate the construction of new building entry points or diverse internal building cabling. These are separate orderable and chargeable features that must be evaluated via the design process. The standard offer is also shown diagrammatically below:

Figure 1. Standard Diversity Offer – Overview

3.10.3.2 Designed Solutions

Requests that fall outside the scope and service specification of the standard diversity offer require the engagement of a Pre-Sales Engineer to create a design, followed by solution pricing.
Potential reasons for a design being required may include:

• Requests for non-IQ Net sites
• Different routing requirements from the defaults
• Different end points (different buildings) at either the A or B end
• Additional diversity features not mandated by the standard service offer definition
• Non-standard components or deployments
• Additional costs necessary to the solution

All designs are supported by a design document in addition to the associated KMZ route maps.
Additional resilience features that can be provided as part of a Wave service, in common with other parts of the Colt product portfolio include:
Dual Building Entry – Establish a second building entry point for the first time or indicate that a service order should use existing multiple entry points.
Customer-defined routing –A single service can be provided according to a defined network route agreed with the customer.

Customers are responsible for ensuring they have appropriate levels of resilience in their network to avoid serious service disruption in the event of an outage on a single wavelength.

3.11 Network Encryption

Encryption is available as an additional feature enhancement for Colt Wave services delivered using the Colt IQ Network. Operating at layer 1, network encryption is an integral component of the service and fully transparent to Ethernet, IP and other network protocols whilst encrypting all data between the service end-points.
Colt’s optical layer encryption services support the very highest levels of performance and security in combination. Being embedded in the optical hardware, they provide scalable, ‘always on’ FIPS 140-2 – certified, AES-256 encryption for high capacity backbone networks with uncompromising wire-speed performance.
Data can be encrypted across the extensive coverage footprint that the Colt IQ Network provides, whilst supporting corporate requirements such as secure customer encryption key management and physical control and security of the encryption hardware itself through location in the customer’s own secure rack environment.
The encryption option is available for the standard optical interfaces supported by Colt Wave in each region.
When ordering Wave with network encryption, customers may choose between the following encryption-specific options:

• The location of the encryption hardware: Customer rack or Colt Equipment Area (CEA subject to Colt approval)
• Encryption key management responsibility: Customer managed or Colt managed

3.12 Performance Reporting

Online Service Performance Reporting is available as a chargeable option within the Wave service portfolio. Customers can access these through the Colt Analytics web portal where up-to-date information on how their service is performing can be retrieved. The service information is stored for an extended period allowing historical reporting and trend analysis to be performed. Reports are available on a network port basis and the following statistics can be viewed:

• Port Availability
• Port Traffic (for Ethernet – to be checked for others)

Online Performance Reporting is available on the Ciena/Nokia-based IQ Network platform for a sub-set of the available Wave service types and bandwidths:

5. Network Access Types

Customer sites can be directly connected to this network using the following access types:

5.1 Colt Fibre

Offices located in buildings that are directly connected to the Colt network will be connected via Colt’s own fibre-optic infrastructure. Colt’s Metropolitan fibre networks deliver high capacity, high speed bandwidth services to Europe’s major business centres, which in turn are interconnected via the Colt long distance network (LDN) delivering high quality reliable services end-to-end.

5.2 Unbundled and Regulated Fibre

In a limited number of locations within Europe and Asia the provision of fibre optic infrastructure in the metropolitan area has been subject to regulation by governmental and regulatory bodies. Colt also uses this fibre unbundled local loop (ULL) to provide network services to customer sites, in conjunction with its own network infrastructure and customer site terminating equipment.

5.3 Partner access types

For sites not directly connected to the Colt network, Colt Wave services can be provided using a mixture of Colt and third-party other licensed operator (OLO) infrastructure and services. Colt interconnects with and manages more than 150 partners in order to connect sites that are outside the reach of the Colt network in Europe, Asia or in other global locations.
Colt will order a circuit or circuits from the OLO on the customer’s behalf, and customers will still be dealing directly with Colt at all times. Colt also takes responsibility for testing the interface between our network and the OLO’s circuit to ensure that the customer’s overall end-to-end Wave service operates seamlessly.
Customer sites can be connected through partner networks using the following access types:

5.3.1 Fibre

Colt can provide Off-Net fibre-optic network connectivity on request and where available by connecting the customer’s service to the fibre-optic infrastructure and services of several partners.

5.3.2 Leased lines (WDM)

Leased lines are circuits or a combination of circuits designated to be at the exclusive permanent disposal of a given customer. Colt can use technically compliant third-party optical services that are themselves provided on WDM platforms or ‘clear channel’ layer 1 optical Ethernet technologies to extend its own Wave services to off-net locations.
In the specific case of 1G, 10G LAN PHY, 100G LR4 and 400G FR4 services that use Ethernet interfaces, optical Ethernet services of the same presentation type can also be used to extend Colt Wave services to off-net sites. The use of such services is subject to Colt’s own technical validation process and inclusion in the list of services approved for use with Colt Wave.

Colt can also use Ethernet demarcation devices to provide sophisticated standards-based Operations Administration and Maintenance (OAM) end-to-end on services that have a 1G or 10G Ethernet presentation.

5.3.3 Dedicated Cloud Access (DCA) Wave

Wave services can also be used to connect to Google. Cloud connectivity on Wave is based on layer 1 optical connectivity and provides dedicated high bandwidth cloud connectivity up
to 100G over Colt’s extensive, wholly owned fibre end-to-end footprint. Specified KMZ path and option for customer-defined routes are supported. The Customer is responsible for establishing layer 3 connectivity into the CSP’s platform.

Other characteristics:

• Colt connectivity: Point-to-point connectivity
• Unprotected / protected service options
• Diversity options
• Encryption feature

6. Security

6.1 Colt

The physical security of our buildings is tightly controlled and access is strictly limited to authorised personnel only. All areas within Colt buildings are secured by means of an electronic access control system to ensure that access is controlled. All people must hold an appropriate pass card while on Colt premises. Non-Colt personnel are not allowed on Colt premises without specific authorisation and prior arrangement. Guests must be vouched for by a Colt host or verified by security in buildings.

6.2 Wave

Because Colt Wave services are separated at the OSI physical transmission layer, it is impossible for customers to intercept or send data to or from any other customer sites via their own access. Colt’s Wave services are delivered utilising a network resource that is reserved for that service and for each individual customer.

7. Service Delivery

7.1 New service order

A new service order is the initial provision of the service to the customer premises, including
the initial configuration of the network to the specification provided in the order form.

7.2 Modifying an existing service

Modifying an existing service consists of the subsequent enabling or disabling of service features, functions and interfaces as well as service changes following initial installation, which are chargeable items.

7.3 Modifying a Wave service

Following provision and installation of a Wave service, customers can ask Colt to enable additional features, functions and interfaces, and request changes to the service. The implementation of changes is chargeable, and some changes may mean that revised rental charges apply. Changes fall into two categories: A and B.

• Category A modifications – Regarded as a new provision in terms of lead times. These are change requests that require physical alternations to the equipment that delivers the service. Examples include changing the interface presentation or adding protection, which is regarded as a new provision in terms of lead times.
• Category B modifications – Require 10 working days lead time. These are configuration changes that can be carried out remotely and within normal working hours and include the following:

-Changing the network path where capacity is already available

-Modifying the service presentation between options that are of the same bandwidth and are supported by the same interface card and cabling types

7.3.1 Out-of-hours changes

Changes that need to be handled out-of-hours must be scheduled and approved in advance, and there is a two-week lead time for scheduling them. (This does not apply to emergency changes.) Ask a Colt Account Executive for more information.

7.3.2 Cessation of service

Cessation of service is within 60 working days from request by the customer. Request for cessation of service may be subject to a charge in accordance with Colt standard terms and conditions. Should the customer cancel their order during installation, Colt reserves the right to raise a charge.

7.4 Fast track installation

Fast Track allows customers to expedite delivery of their order and receive their service on a date specified by the customer (generally prior to the standard lead time), or, if this date is not possible, on the earliest possible date.
Fast Track installation is available for all On-Net sites in all Colt geographic locations. If Fast Track is possible, Colt will provide a Fast Track delivery date based on technical feasibility, which customers can accept or reject. If accepted, the Fast Track option incurs an extra charge in addition to the standard installation fee.
Consult a Colt Account Executive for more information.

7.5 Demarcation point

The demarcation point for Colt services is the customer interface at the Colt access equipment (normally at the base of the Colt cabinet). If customers require in-house cabling from the Colt cabinet to their equipment, this will be a chargeable service.
If Colt installs cabling on a customers’ behalf, the demarcation point remains the same: the base of the Colt cabinet. Colt is not responsible for fault-finding on the in-house cabling.

8. Service assurance

Colt provides a high level of service assurance:

• The core network is proactively monitored
• A local language help desk is available 24 x 7
• Colt Online provides a web-based portal that enables customers to view bills and trouble tickets

8.1 Customer service

Colt has a high quality European fibre network that enables the provision of an annual target service availability. The target availability depends on the service taken and the location of customer sites. The fault help desk is available 24 hours a day, seven days a week.
Customers can report a fault at any time by contacting the Customer Service Centre and speaking to a representative in their local language.
When a service is provisioned, customers are issued with a unique service reference for each circuit that they should always use when reporting faults. The contact number for fault reporting is specified in the handover pack.

8.2 Colt Online

Colt Online is an intuitive, user-friendly application enabling new and existing Colt customers to interact with Colt via a secure Internet connection without the need to speak to a Customer Service Agent or Account Executive.
Every Colt Online customer is provided with an administrator account for a defined user within their organisation. This administrator has full access to the available features for all their customer accounts and sub-accounts, including:

• Search and view any bill from the previous six months in .pdf format (not available in Switzerland due to data protection legislation)
• View the status of any order in the delivery process
• View the status of any ticket (covering faults, enquiries, service requests) in real-time
• Search and view all live services
• View an account dashboard, summarising the four features above

8.3 Service Monitoring

The Colt network is proactively monitored and maintained by Colt.

8.4 Automated Monitoring and Notification

Colt Wave services include an optional proactive notification service, which means that Colt proactively monitors the service and can notify customers of any service-affecting faults via e-mail or SMS. Proactive Fault Notification is a customer selectable service feature.
Please refer to the section 3.13 for specific details on where this feature is available.

8.5 Planned Maintenance

In order to ensure performance and security for all customers, Colt occasionally performs maintenance works that may cause customer’s service being unavailable. Please refer to the SLA documents for more details on the maintenance works. Unless a critical intervention is required, Colt will endeavour to have the maintenance works occur during non-working hours as follows

Please note

• Colt will endeavour to accommodate the Maintenance Window as per the above table. However, Colt cannot guarantee it as some works will require longer windows or due to exceptions such as Government or local regulations and other reasons beyond Colt’s Control.
• The above table does not cover Planned maintenance of network components owned by 3rd party and Colt will inform the Customer such maintenance windows as and when Colt is made aware of such works.
• The above maintenance window is applicable for both Service Affecting and non- service affecting works

9. Commercials

9.1 Billing

The customer bill is available on paper or CD-ROM and details:

• Service installation charges
• Service rental charges
• Discounts, where applicable
• Other charges and credits

Customers are provided with a single freephone point of contact for all service enquiries including billing enquiries. For detailed billing enquiries, customers can be transferred to a specialised billing department.
Charges will be applied per site based on the bandwidth selected and the location of the site.

9.2 Installation charges

One-off installation charges will be billed in full in the first invoice issued after installation. This will usually be within 30 days of service delivery. In addition, any moves, changes or modifications will incur one-off charges.

9.3 Rental charges

Customers can opt to pay monthly, quarterly or annually. Where no option is indicated, monthly billing will be set as default. All rental owed under the service will be payable in advance.

9.4 Additional features

The charges for enhanced resilience options are built into the service charges.

10. Performance Objectives

The performance objectives of the service are included in the Service Level Agreement (SLA).

10.1 Service Availability

Service availability is defined in full in the SLA, which is a separate document and includes details of the rebates if the targets are not met.

10.2 Fault Handling

Faults can be reported via the local telephone numbers as described in the handover pack, 24 hours a day, 7 days a week. The period when the service was not available will be measured from the time such condition is reported by the customer and a trouble ticket is opened by Colt to the point when Colt resolves the trouble ticket and informs the customer that the service is available. The customer shall be deemed to have been informed of service availability if Colt has unsuccessfully tried to contact the customer. Fault handling is defined in full in the Service Level Agreement (SLA).

10.3 Round Trip Delay

Round Trip Delay (RTD) is the time taken for layer1 traffic to traverse from a source site to a destination site and back again.
The RTD for Colt Wave Services are calculated on an individual circuit basis. Upon customer request, Colt will provide an estimate of the expected RTD for a given service as part of the solution design during the Pre-Sales process. At customer request this can be attached to the service order. An RTD estimate attached to a service order constitutes the RTD target for that individual service.
The RTD handling is defined in full in the Service Level Agreement (SLA).
