Is GPON a contended service?
Entanet manages the access technology by splitting and continuing the pure fibre connection to no more than 8 business customer premises. As a result, your available download speed will not fall below 300Mbps. Our pledge to customers is that if we see evidence that their experience is significantly compromised by GPON delivery, we’ll add capacity to fix it.
Is it a full-fibre solution?
Yes, delivered across CityFibre’s full-fibre revolutionary network.
Is it a fully managed solution?
GPON is available wires only, or with managed hardware subject to network availability.
What service level agreements are available?
We provide an improved service level agreement over standard ISDN with a 6 hour fix.
Is any hardware provided with the service?
Yes, if a managed service is ordered a router is provided. For a wires-only service a network termination device is provided.
How do I order a Full Fibre VoIP service?
It’s easy. Order your 500Mbps GPON circuit via the EQT in synergi then order and configure a new Hosted Voice service or SIP Trunk via synergi. Email with the circuit and VoIP references within the same month; we’ll combine the services and you’ll receive your discounted VoIP price.
How long will it take to install the solution?
Installation of the GPON service is typically 45 working days, subject to site survey and cooperation with the process by other agencies such as local councils and landlords. The good news is that as we manage the provisioning process ourselves, your dedicated provisioning agent will be able to keep you and your customer updated on progress as the order makes its way through the process to activation. Activation of your SIP trunks or Hosted Voice solution is immediate, if you choose new telephone numbers. If you are porting your existing numbers, there is no guaranteed lead time across industry.
Can I retain my customers existing IP PBX equipment?
Yes and you can choose the free SIP Trunk option to utilise with the existing equipment.
What’s the difference between SIP Trunks and Hosted Voice seats?
SIP Trunks provide straightforward gateway access to a network for call termination where as a Hosted Voice solution is a complete telephony system with extensions, incoming numbers, voicemail etc.
Can I add or remove hosted voice seats or SIP trunks?
Yes. The solution includes 20 free Hosted Voice seats or 30 free SIP Trunks as standard but you can add more easily via synergi for an additional cost.
Can I add auto attendants and call queues/hunt groups to a Hosted Voice instance?
When you order a hosted voice instance two queues/hunt groups and a single-level auto-attendant are included.
Can I port existing numbers?
Is this service available nationally?
GPON is currently available via our CityFibre full-fibre network in towns and cities across the UK and we are expanding coverage over time. You can check availability via the Ethernet Quoting Tool in our partner portal, synergi.
