After you’ve placed new service orders with your CNSP they will deploy them to your sites ahead of your agreed migration date.
The amount of work and time involved in this will vary greatly depending on what services are ordered and site locations. This could be something as simple as delivering a new router, which usually takes around 3 months, up to having to complete civil engineering works to install new network cables, which could take up to 12 months.
If you think you will need major works, we recommend you make your CNSP aware as soon as possible.
You should also:
- identify and assign suitable site contacts, who will be responsible for specific HSCN migration for the site - see the migration checklist for more information on these activities
- communicate plans to all site owners and agree site contacts - the site contacts will be the ones responsible for the migration on the day so it is important to keep them informed
- ensure CNSP site surveys have been undertaken and any civil works and excess costs have been estimated and can covered within the budget
Order new, or update existing, network room equipment before the migration. Check you have enough cabinet and rack space for any new equipment. You’ll need space for both your N3/TN equipment and HSCN equipment if you plan on dual running for a period. If the equipment is not ready on the day, or it is not fit for purpose, this could cause your migration to fail.
Define the specific circuit locations for installation at your sites. Communicate this clearly to your CNSP and the site contact, label these on site and take photographs for the engineers to refer to where possible. There may be multiple different engineers visiting your sites during the migration journey and making sure they can find the circuit locations quickly and accurately will make these visits go smoothly.
Request delivery updates from your CNSP and keep your site(s) informed of progress and planned visits. Cancelling (and rebooking) site visits from your CNSP or Openreach because site staff aren’t aware and prepared for them will cause delays to your migration date.
