3.1 The CSL Wires-Only Broadband Service provides Broadband services using ADSL and FTTC access technologies carried over the CSL Network and any third party network that CSL uses to offer the Service. The Service offers the Customer the choice to purchase FTTC/ADSL only Services or both FTTC/ADSL and PSTN Service, (without voice calls).

3.2 The Service will consist of the following Wired Path components:

(a) PSTN installation to the remote Customer site with Standard Care levels, unless the Customer has chosen to use their own BT supplied PSTN line; and

(b) ADSL or VDSL installation to the remote Customer site with Standard Care levels

3.3 The Service is available from within the UK only and only on Wholesale Line Rental (“WLR”) lines with BT number ranges. It is not available in (i) the City of Hull; (ii) the Isle of Man; (iii) the Channel islands; or (iv) the Republic of Ireland (Eire).

3.4 For supply of Wired Path components to site, the following clauses shall apply:

(a) All Wired Path components are subject to availability at the site and may require site surveys

(b) Service availability checks are not an absolute guarantee that the Wired Path access method or specific variant can be provided.

(c) The provision of the Wired Path component is conditional upon confirmation from CSL that it is able, and agrees to provide the access method and, if relevant, installation and/or survey services, at the relevant Customer site.

(d) Where delivery of Wired Path components to a site is subject to excess construction charges (such as laying extra cabling or trenches), CSL will pass on details of such charges to the Customer for approval before proceeding any further with the order

(e) Where an ordered Wired Path access circuit or service, cannot be provided, the Customer may order an alternative or cancel such Wired Path service or access circuit, without incurring an applicable recovery charge (i.e. charges for recovering CPE from Customer premises). In these circumstances, the Customer shall not be entitled to any compensation in respect of such cancellation.

(f) For each planned installation, the Customer will provide a site contact name/number who will grant access to the site for subsequent installation activities and confirm the exact location for the installation of the Wired Path component.

(g) CSL shall notify the customer of the Agreed Delivery Date for new installations. Each Wired Path component and each Connection at any Customer Site may have different Agreed Delivery Dates. CSL will use reasonable endeavours to complete installations by the Agreed Delivery Dates but does not guarantee those dates.

(h) The Customer will be deemed to have accepted the Service on the Agreed Delivery Date unless it cancels the Service before the Cancellation Deadline or notifies CSL within five Working Days that the Service was not available on that date, in which case it will be deemed to have accepted the Service on the first date on which the Service is available

(i) If the delivery of the Service is delayed beyond the Agreed Delivery Date due to an act or omission of the Customer (including failing to provide complete information, accurate information and/or failure to procure any applicable consent, approval or access from any third party) or if the Order is modified after the Cancellation Deadline, CSL may start charging the customer from the Agreed Delivery Date and/or claim reasonable costs (including third party provider costs) that result from the delay, modification or cancellation.

(j) CSL shall inform the Customer of the date for any required site visit but may not confirm an exact time. It is the Customer’s responsibility to ensure site access is granted and available on the agreed date or missed appointment charges will become payable. Flexible appointments may be available at extra cost.

(k) In its use of the Service, the Customer shall only use Equipment which has been approved by CSL as compatible with its Network.

(l) The customer may cancel the Service or any part of it (subject to the payment of CSL’s reasonable costs and expenses including of any third party provider charges incurred by CSL as a result of such cancellation) at any time before the Cancellation Deadline by providing written notice to CSL.

3.5 Termination of previous service providers:

(a) It is a condition of this Agreement that where the fulfilment of a Customer Order requires CSL to terminate and migrate any existing FTTC/ADSL or fixed line agreements (whether such agreement is in the name of the Customer or any other third party, the Customer: authorises CSL to terminate the Customer’s and/or any relevant third party’s existing agreements; shall be solely responsible for providing all telephone numbers, addresses and other information which CSL requests in connection with any such termination and migration; and shall, before the Agreed Delivery Date, procure that all Users and any third party whose existing FTTC/ADSL or fixed line agreements are to be terminated and migrated in connection with any Order authorise CSL to terminate their agreements with previous FTTC/ADSL service providers and previous fixed line service providers in respect of all relevant Connections and comply with all reasonable requirements in connection with such termination and migration (including providing access to any relevant Site on the Agreed Delivery Date).

The Service is provided using, at CSL’s option, ADSL and FTTC access technologies carried over CSL’s Network and any third party network that CSL uses to offer the Service.

4.1 Baseline Service

The Service offers the Customer the option to purchase either FTTC/ADSL only services or both FTTC/ADSL and fixed line phone services in accordance with the table below (“Baseline Service”).

Baseline Service



CSL provides only the FTTC/ADSL Connection, with no fixed line service. The Customer uses its existing provider for fixed line and voice calls, which must be a PSTN line provided over the BT cabling network.

FTTC/ADSL plus fixed line services (without voice services) CSL provides FTTC/ADSL Connection and fixed line services. The Customer pays monthly line rental for the fixed line. A bar will be placed on the line to prevent voice calls from being made.

4.2 Fixed Lines

Fixed line services will use a connection to the CSL network via BT Openreach exchange lines that are installed or taken over by CSL and supplied to the Customer as requested on the order form or which already exist when the line is taken over. All lines will have outbound calling barred.


5.1 When installation and/or resolution activities require engineering attendance at Customer Premises, the Customer will be responsible for providing access to the site, as requested and coordinated by CSL.

5.2 Target Resolution Times for all Wired Path components are subject to site access being granted by the Customer if and when required.

5.3 Target Resolution Times for Wired Path Components

FTTC/ADSL Components

1.1 Where troubleshooting concludes that a fault exists with the underlying ADSL/FTTC components to a site, target resolution times will subject to the associated Care Level that has been subscribed to for that component. The Service includes Standard Care levels on these components as defined in the table below. Enhanced Care levels are available at additional cost.

ADSL/FTTC Care Level

Period of Cover

Target Resolution Time

Standard Care 08:00 to 18:00 Working Days 48 Hours

1.2 Where an ADSL/FTTC fault is reported outside of the period of cover applicable to the relevant Care Level which the Customer has subscribed to, the fault will be treated as if it had not been reported until the beginning of the next period of cover and this will be the start time for the Target Resolution Times above.

PSTN Components

1.3 Where troubleshooting as part of an Incident concludes that a fault exists with the underlying PSTN component to a site, Target Incident Resolution Times will be further subject to the associated Care Level that has been subscribed to for that component. Where CSL have provided the PSTN component as part of the Service, the CSL Wires-Only Broadband Service includes Standard Care levels on the PSTN component as defined in the table below. Enhanced Care levels are available at additional cost that offer quicker target Resolution Times and flexible engineering appointments.
