Introduction
If full fibre is available to you on our website, fibre network has been constructed to be within close range of your property. All that remains for your installation is a 'final drop' for the full fibre optic cable from the nearby CBT connection point (which could be overhead on a pole or underground in a chamber) to your property.
Fibre cable deliver to your property
The new full fibre cable can either be installed:
- Overhead (from a nearby telegraph pole)
- Underground (through existing/new ducts)
Install Category Stage
Openreach classify their orders into either 1 Stage or 2 Stage. CityFibre orders will be completed in 1 stage.
1 Stage Install Category
A 1 stage order is the most straight forward install.
A single engineering visit is required, and you will be required to be at home for this visit.
The engineer will firstly install the external fibre cable overhead or underground (as determined by your order) to your property. They will then install a CSP (customer splice point) box at the point where the cable is to be brought inside. An internal fibre cable is then routed inside.
2 Stage Install Category
A 2 stage install is more complex and means that 2 or more visits will be required to complete the install. Third party permissions may need to be obtained, or more extensive works carried out. However you will only need to be at the property for the final commissioning appointment. All other works take place outside and do not require you to be in attendance.
Openreach Service Network Notes (SSN) Table
| Fibre cable delivery | Openreach Service Network Notes (SNN) | Openreach Install Category | Approximate lead time impact | Openreach Scenario |
Setting customer expectations |
|---|---|---|---|---|---|
| Overhead | OH Feed with no anticipated issues | 1 Stage | Standard |
Overhead feed – no issues anticipated. |
Anticipated to be a straightforward install conducted in 1 visit with an overhead fibre optic feed from the nearby serving telegraph pole to your property. |
| OH Potential Wayleave issues | 1 Stage | Standard +1 plus weeks |
Potential 3rd party wayleaves required |
Anticipated to require a wayleave (legal permission) for the overhead fibre optic feed from the nearby serving telegraph pole to your property. Potentially this cable will route over private property? Depending on the 3rd party, the permissions could take some time to organise. Until these permissions are granted, the install works cannot commence. |
|
| OH Feed with Line of sight problems Trees | 1 Stage | Standard +2 weeks or more |
Light tree cutting or minor pruning may be required which is achievable on the day. | The overhead fibre optic cable from the nearby telegraph pole to your property is likely to get caught in nearby trees/foliage, and therefore this needs pruning to prevent damage to the cable. | |
| OH Feed hoist required | 1 Stage | Standard +1 weeks |
Wherever hoist is required – pole or customer end | The telegraph pole or your property cannot be safely climbed with a ladder, so a vehicle hoist/cherry picker is required. | |
| OH Feed traffic management required | 2 stage | Standard +3 weeks |
Bus route, national speed limit roads, dual carriageway |
Permission will be required from the local authority for traffic lights/management to allow the safe installation of the overhead fibre optic cable to your property. |
|
| OH Feed potential Line of sight problems | 2 stage | Standard +2 weeks |
Obstructions / specialist tree cutting / Installation issues / excessive distances / Pole replacement |
Third parties will be required to investigate the potential obstructions and challenging overhead cable route, and deal with any issues (pruning trees) before the install can complete. |
|
| OH Property fed from the rear | 1 Stage | Standard | Property fed exclusively from the rear – longer L2C task |
The fibre optic cable will come in overhead from a pole at the rear of your property. The installation task may take longer than usual, but it should be completed within one appointment. If you have a PM appointment slot or there is poor light/weather, then there is a chance that this appointment may be delayed/extended into another day. |
|
| OH Feed joint user pole | 1 Stage | Standard | Blue ladder & two engineers required |
The fibre optic cable is coming in overhead, but requires multiple engineers to safely install due to the telegraph pole set up. If you have a PM appointment slot or there is poor light/weather, then there is a chance that this appointment may be delayed/extended into another day. |
|
| OH Feed alternate L2C solution required | 2 stage | Standard +2 weeks |
Tetra can’t be used. Rendered or Listed buildings, shop fronts |
The fibre optic cable is coming in overhead, but the engineers cannot safely use the Tetra ladder system (where it's anchored into a wall to provide safety). Therefore another option needs to be devised. |
|
| OH External CBT Complex L2C | 2 stage | Standard +2 weeks |
Externally fed wall premises driving complex L2C install |
The fibre cable is routing overhead to your property, but it may take a complex route to get to your property, for instance, it may route along the eaves/wall of your neighbours properties. |
|
| OH Access to CBT restricted | 1 Stage | Standard | Access required e.g. pole in third party garden or behind locked gate |
The fibre connection point (CBT) is located on a pole which is located on 3rd party land (e.g. your neighbours property). Access needs to be arranges with this 3rd party so that the engineer can safely climb and fit your fibre cable from this pole (CBT) to your property. |
|
| OH prebuilt to the CSP | 1 Stage | Standard | OH Network – build to the wall |
A fibre cable has already been pre-installed to your property. All that remains is for an engineer to visit to do the final install installation works and commission the service. |
|
| Underground | UG Duct rod and roped | 1 Stage | Standard | DUCT successfully rodded with a rope left in |
The fibre cable is routing underground to your property in a duct. There's a rope available within this duct to help pull the new fibre cable in. This should be a straight forward 1 visit install. |
| UG congested duct | 2 stage | Standard +3 plus weeks |
Existing duct is blocked or where both ends of the duct are not visible |
The fibre cable is routing underground to your property, but the duct is congested/blocked/damaged and needs repairing/replacing. This will usually require a civil engineering contractor to visit to fix, and this will take time to plan and organise. If the duct routes over third party land, or in the public highway, then 3rd party permissions may be required causing additional delays. |
|
| UG Potential Wayleave Issues | 2 stage | Standard +3 plus weeks |
Potential wayleaves required |
The fibre cable is routing underground to your property, but the route takes it over 3rd party land which requires permissions to be arranged before installation works can commence. Depending on the 3rd party, the permissions could take some time to organise. Until these permissions are granted, the install works cannot commence. |
|
| UG premises served by 2.5 Inch plastic duct 56 | 1 Stage | Standard | Standard UG duct e.g. duct 56/54 | The fibre cable is routing underground in a 2.5 inch diameter duct, and it should be straight forward to install the new fibre cable within this to your property within 1 visit. | |
| UG premises served by 1 Inch duct 100 | 2 stage | Standard but could be +2 plus weeks |
High risk of civils due to duct type (other than 56/4) e.g. 1-inch duct 100 |
The fibre cable is routing underground in a very small diameter duct, and potentially this is too small to pass the new fibre cable within it. Therefore if the fibre cable cannot be pulled into the duct, then civil engineering will be required to replace the duct for a larger one. Depending on the location of the duct, this will take some time to organise. |
|
| UG Feed traffic management required | 2 stage | Standard +3 weeks |
Bus route, national speed limit roads, dual carriageway |
The fibre cable is routing underground in ducts, however some of the ducts and manholes need to be accessed in locations that require additional safety measure to be in place (traffic lights). These require permits to be issued to the local authorities, and they can take a number of days to issue. |
|
| UG pre built fibre to the CSP | 1 Stage | Standard | Build to the wall |
A fibre cable has already been pre-installed to your property. All that remains is for an engineer to visit to do the final install installation works and commission the service. |
|
| Direct in ground | UG partial Direct In Ground | 2 stage | Standard +4 weeks **Could be months.** |
Historic DiG – premised fed via armoured cabling |
The fibre cable is routing underground, however there is no duct in place, and the existing copper cables are directly buried in the ground. Therefore civil works are required to install a new duct so that the fibre cable can be installed. Depending on the location of the works, this may require 3rd party permissions, local authority permits, and there are lead times with the planners and civil engineering teams. The installation could take a long time. |
| UG Pre built to curtilage Hard | 2 stage | Standard +2 weeks **Could be weeks.** |
Tarmac / Slabs / Concrete |
The fibre cable is routing underground, however there is no duct in place to your property, and the existing copper cables are directly buried in the ground. There may be some works required to install a duct or the cable underneath tarmac/ paving slabs/ concrete. Depending on the location of the works, this may require 3rd party permissions, local authority permits, and there are lead times with the planners and civil engineering teams. The installation could take a long time depending on the complexity. |
|
| UG Pre built to curtilage Soft | 2 stage | Standard +2 weeks **Could be weeks.** |
Dig in the Grass |
The fibre cable is routing underground, however there is no duct in place to your property, and the existing copper cables are directly buried in the ground. There may be some works required to install a duct or the cable underneath grass (soft dig). Depending on the location of the works, this may require 3rd party permissions, local authority permits, and there are lead times with the planners and civil engineering teams. The installation could take a long time depending on the complexity. |
|
| UG Pre built to curtilage No Dig | 1 Stage | Standard | Terraced / Semi small frontage with easy route to the wall |
A fibre cable has already been pre-installed to your property. All that remains is for an engineer to visit to do the final install installation works and commission the service. |
|
| To be phased out | UG Proven Clear | 1 Stage | Standard | DUCT rodded and potentially roped |
This is a generic wide-ranging description, therefore Openreach are slowly withdrawing these SSN options, and replacing with one of the existing Underground SSN options. However, this option is likely to be straight forward as a duct exists which potentially may be roped and can be used to pull in the fibre cable. However the duct may be too small, or there may be wayleave issues. Therefore there's a small risk of challenges. |
| UG Pre built to curtilage | 2 stage | Standard +2 plus weeks |
To be phased out replaced by granular built to curtilage SNNs |
This is a generic wide-ranging description, therefore Openreach are slowly withdrawing these SSN options, and replacing with one of the existing Underground SSN options. However, this option is likely to be complex. It could either refer to a ducted option, or direct in ground option. |
|
| UG Feed Not Evaluated | 2 stage | Standard +2 plus weeks |
To be phased out replaced with other UG SNNs |
This is a generic wide-ranging description, therefore Openreach are slowly withdrawing these SSN options, and replacing with one of the existing Underground SSN options. However, this option is likely to be complex. Openreach's planners have identified that the fibre route would be underground, but they have not identified the classification - whether this is ducted or direct in ground. However, this option is likely to be complex. |
