# What Is a Fibre Line Release and Why Does It Matter?

Source: https://urbanx.co.za/knowledge-hub/switching-moving-managing-fibre-service/fibre-line-release-explained

**Answer:** A fibre line release is the administrative step that ends the old ISP’s assignment to an existing FNO line so another ISP can request service on it. It does not remove the cable or normally require moving the ONT. Cancellation notice, service termination, release and new activation can occur on different dates.

### What is being released?

The physical fibre remains connected to the property. What changes is the service association in the FNO’s operational system.

Before release, the record can be understood as:

`Premises → FNO line → Current ISP service`

After the old service ends and the line is available:

`Premises → FNO line → Available for supported activation`

After migration:

`Premises → FNO line → New ISP service`

Operator portals use different labels, and not every FNO exposes a customer-facing release state. The concept is more important than the wording.

### Who requests the release?

The customer normally cancels with the ISP that holds the service agreement. That ISP is then responsible for cancelling the corresponding access service with the FNO.

ISPA’s best-practice recommendations say ISPs should take responsibility for cancelling client services with the relevant FNO and should respect a customer’s wish to move by notifying the FNO of the correct date in good time.

The new ISP may submit or prepare a migration request, but the customer should not assume that this automatically cancels the old contract.

### Why a release is not immediate by default

The old ISP may still have:

- a contractual notice period;
- a future scheduled service-end date;
- an unpaid or disputed final balance;
- equipment-return conditions;
- an FNO cancellation cut-off;
- an open request to withdraw or amend cancellation;
- evidence that the transfer request is for the wrong premises.

The FNO also needs to avoid an unauthorised disconnection. ISPA recommends notifying the current ISP before a migration and giving it a chance to dispute the request.

These protections must not become an unreasonable indefinite block. If the effective date has passed and no clear reason is given, request a formal status and complaint reference.

### Cancellation date vs release date

| Event | Meaning |
| --- | --- |
| Notice received | The old ISP has accepted the cancellation request |
| Contract/service end | The customer’s service is due to terminate |
| FNO cancellation submitted | The ISP has told the network operator to end its access service |
| Line released | The FNO no longer assigns the line to the old ISP service |
| New activation | The gaining ISP is provisioned on the line |

One email saying “your cancellation is processed” may not confirm every row. Ask for the exact state that the new ISP needs.

### Information to include in a release query

- account holder and account reference;
- exact service address and unit;
- FNO name;
- ONT, circuit or line identifier;
- cancellation submission date;
- requested service-end date;
- cancellation acknowledgement;
- new ISP or migration reference if already placed;
- proof of occupation if the old service belongs to someone else.

Avoid sending only “please release my line urgently.” A useful request lets the ISP identify the correct access service without guessing.

### When the line belongs to a previous occupant

The new occupant is not the old ISP’s customer and may not know who that ISP is. The gaining ISP should use the FNO’s change-of-customer or disputed-transfer process.

ISPA recommends a mechanism that can require proof that the new applicant is the most recent resident or property owner, notify the current ISP and allow at least a short response opportunity. The applicant should provide legitimate occupancy evidence rather than trying to obtain or cancel the previous customer’s account.

### What a release does not do

A line release does not by itself:

- cancel every payment obligation under the old agreement;
- refund overlapping charges;
- transfer an ISP-owned router;
- move the line to a new address;
- migrate between two different FNO networks;
- repair damaged fibre;
- guarantee the new ISP’s activation time;
- erase account arrears or a contract dispute.

Each of those has a separate owner and process.

### If a promised release is missed

1. Confirm the effective service-end date in writing.
2. Ask the old ISP whether the FNO cancellation was submitted.
3. Give the new ISP the cancellation reference and line identifier.
4. Ask the new ISP for the exact FNO state it can see.
5. Correct any address mismatch.
6. Request a complaint reference from the party responsible for the missed action.
7. Escalate through the documented complaints process if it remains unresolved.

Do not repeatedly reboot or reset the ONT. A line-assignment problem cannot be fixed by local troubleshooting.

## Frequently Asked Questions

**Is a line release the same as cancellation?**

No. Customer cancellation should trigger the process, but release is the FNO-side availability state needed for another supported service.

**Can the FNO release the line directly for me?**

Some FNOs publish migration or reconnect channels, but the customer’s agreement is with the ISP. Start with the relevant ISP unless the operator directs otherwise.

**Must the ONT be removed for release?**

Normally no. The release is administrative, and the fixed FNO equipment should remain at the premises.

**Can a line be released while I still owe the old ISP?**

Process and contract terms vary. Outstanding amounts remain a separate obligation even if service ends. Ask the ISP for the contractual and FNO status separately.

**How long does release take?**

There is no responsible universal time. It depends on the effective cancellation date, FNO workflow, dispute checks and whether the records are correct.
