Netvoip/Nexphone Reseller guidance for Operator Number Portability in the Swiss telephony network.

Content

1  Introduction

As required by ComCom Regulations, telecommunications service providers (TSPs) in Switzerland must offer their subscribers the option of retaining the same telephone number should they wish to change telecommunications service provider (Operator Number Portability).
This netvoip/Nexphone Reseller guidance explains the process of Number Portability for telephone services, based on the fixed network (ISDN/PSTN/VoIP/DDI) within the Swiss telecommunications network as regulated in Teldas Operator Number Portability (ONP) Document for Implementation.

1.1  General requirements and specifications

NPRN
NPRN 98019 - Nexphone AG
PoA Email address: onp.poa98019@nexphone.ch
Reseller Portal Email Notification sender: noreply@nexphone.ch

Number format
The valid phone number format is 0XX1234567 (National).

Working Days / Hours
Working Days are Monday to Friday less Swiss National Holidays. Official working hours are 08:00 to 17:00. The ONP process is based on working days (wd) calculation.

Synchronisation between Reseller Portal and Teldas INet-Server
The data synchronisation between Reseller Portal and Teldas INet-Server runs once at every full hour (xx:00). 

General steps Number Portability
1 - Subscriber request for Number Portability 
2 - Recipient service provider issues a Workorder for ONP
3 - Donor sends an acknowledgement within 2 working days (accept or reject)
4 - Recipient sends Synchronisation 1 - 3 workingdays before Porting date/time (automated process)
5 - Recipient and Donor make the Activation / Deactivation / Routing at Porting date/time (automated process)
6 - Recipient sends the Handover after Porting date/time (automated process)

1.2  Definition of Terms

Donor service provider
The Donor service provider is the service provider to which the subscriber was connected before the change of telecommunications service provider. The term DONOR as used in this guidance means the Donor Service Provider.

Number Range Holder
The Number Range Holder (NRH) is the service provider to which the subscriber was connected to before the first number portability to another telecommunications service provider. Therefore the subscriber phone number will always belong to the number range of the Number Range Holder.

Number Portability Routing Numbers NPRN (Verbindungsteuerungsadresse)
An address, which is allocated to a portable number by a TSP in order that calls can be routed correctly to a RECIPIENT service provider. The network routing address cannot be dialled by the subscriber and clearly identifies a telecommunications service provider nation-wide. The NPRN is allocated by OFCOM and has the format 98xxx for Switzerland.

Public Holidays
Public holidays are usually the Swiss national holidays. Local holidays are not taken into account and should therefore be taken into consideration by the Operators additionally when a porting request is linked to a line transfer.

Recipient service provider
The Recipient service provider is the service provider to which the subscriber will be connected after the 
number portability. The term RECIPIENT as used in this guidance means the Recipient Service Provider. 

Subscriber
Legal entity having signed the service agreement with the TSP for the usage of the telephone number to be ported (customer of the TSP). 

TSP INet-Server
The Teldas TSP Inet-Server contains the centralised offline database for ONP which records all ported Swiss numbers data. It manages all concerning aspects of the number portability process between the TSPs. 

Workorder
TSP Inet-Server Order-ID of number port request. Unique for each number port request.

1.3  General Rules for Contract Cancellation and Timing of the Process

1.3.1  Power of Attorney (PoA) 

The Recipient must possess a Power of Attorney with valid signature(s) from the relevant Subscriber. Signature verification for companies as per Zefix source (https://www.zefix.ch).

The PoA is required for a new number port request always.

The valid date for the given notice on the subscriber's contract is the date of signature on the PoA. Note that in case the subscriber has given notice by written form directly to his current operator prior to signing the PoA, the notice period as per first acknowledgment by the Donor should be retained to define the end of contract porting date.

The PoA remains valid for a maximum period of 1 month following the subscriber’s next contract expiring date at his existing operator. Example: PoA signed on 5.02.2021, subscriber under contract until 30.06.2021, PoA valid until 31.07.2021.
If not stated else way in a mutual agreement between Recipient and Donor: The Recipient must send a copy of the PoA to the Donor electronically within 4 working hours after the Workorder has been initiated in Teldas INet.

In case you require to receive the PoA from the Recipient provider, you can reject the Workorder with reject reason 14. The Recipient is then obliged to send the PoA.

1.3.2  Period of Notice and any minimum subscription time period / early termination fee

Case 1 - Subscriber wants to respect contract end date to avoid paying any penalties at the Donor:
Workorder must be initiated with the field PoA Type = Respect contract end date. In case the Recipient enters a wish date and it is before the end of the notice period, the Donor must reject it if a penalty would be applied to the subscriber. The rejection reason code 7 is to be used.

Case 2 - Subscriber wants to port as soon as possible, even if penalties are to be paid at the Donor:
Workorder must be initiated with the field PoA Type = Early termination penalty. The Donor can’t reject the Workorder for the reason that the wish date is before the end of the notice period.

Workorders with a desired porting date more than 280 working days after the issuance date of the Workorder will not be accepted by the INet-Server.

The valid date for the given notice on the subscriber's contract is the date of signature on the PoA. When a valid PoA has been received, the termination of the contract remains valid even in the case of a rejection of the porting request. In the case of a re-issued PoA, the date of the first PoA remains valid except in the case of a wrong telephone number.

The number shall be reserved for 30 calendar days after the end of the notice period. During this period the number can be reactivated if required by the former owner of the number. Porting requests initiated during this period have to be accepted as if the number was still active.

1.3.3  Timing of the processes

The minimal time to be expected for PSTN/ISDN, DDI porting is 7 working days.

Acknowledgement Accept / Reject: The Donor must accept or reject the Workorder within 2 working days. When it proves necessary to reject a Workorder, the Donor must give the reason(s) for rejection of a workorder and when required additional details in the free text description field. If no acknowledgement has been made within the defined time, the Workorder will be considered as having timeout status.

When the Recipient has not filled in the Porting date field, the Donor has the possibility to accept the workorder filling in the Porting date with the contract end date. This is to be used when the field “PoA Type” is set to “Respect contract end date”. Note that the Donor is allowed (but not obliged!) to reject the workorder in case the Porting date would be too far in the future (>280 wd). 

1.3.4  Authorised Reason for rejection from the Donor

Hereafter the list of reject reasons which can be used and the type of information the Donor needs to provide within the free text description field. Note that the Donor is not allowed to reject a request on the grounds that the subscriber has unpaid outstanding bills. Even if the Donor has deactivated or suspended the number or even cancelled the subscriber contract, the porting must be granted within 30 calendar days after contract end date.

2  Number portability - Port in

2.1  Submit New Number Port request (Port in)

A request for number portability (Workorder) to the Donor service provider of the number can be started by creating a New Subscription. 

2.2  Number Port request failed (Port in)

Whenever a number port request cannot reach Teldas INet-Server due to an invalid request, no Workorder-ID is handed out. The port request will fall in status failed.

2.3  Workorder Accepted (Port in) 

2.4  Workorder Rejected (Port in) 

2.5  Represent Workorder (Port in) 

2.6  Cancel Workorder (Port in) 

3  Number portability - Port out

A number port out request in status NEW or REPRESENT must be acknowledged within 2 working days (accept or reject).
In case you require to receive the PoA from the Recipient provider, you can reject the Workorder with reject reason 14. The Recipient is then obliged to send the PoA.

3.1  Accept Workorder (Port out)

3.2  Reject Workorder (Port out)

4  Timeout Fault Management (for late validation by the Donor)

When the Donor does not react within the specified or agreed time to accept/reject a Workorder, the process falls into a timeout status called ‘Timeout A’ for 4 working hours.
If the time limit of ‘Timeout A’ expires without sending the required message, the timeout status will change to ‘Timeout B’ for 1 working day. 
If ‘Timeout B’ expires, the timeout status will change to ‘Timeout H’.
If  ‘Timeout H’ expires, the Workorder will be canceled (Cancel H).

Note that SLA penalties occur for a Timeout.
