PQS1 - Supply Time for Initial Network Connection
1. Definition:
1.1 The PQS1 is intended to measure the time duration, in calendar days, from the instant a valid service request is made by a client regarding the supply of a connection by the providing undertaking for access to the public telephone network at a fixed location, to the instant that undertaking actually provides a publicly available telephone service at a fixed location, regardless of the supporting technology.
1.2. To calculate the present parameter, a valid connection request means any solicitation made to the providing undertaking and accepted by it, concerning:
- a new connection to the service of access to the public telephone network at a fixed location provided by the undertaking (first connection of a specific client or a new connection as result of a change of the respective address); or
- an additional connection of a client of the undertaking (for the same address or a different one); or
- migration from the analogue line of a client of the undertaking to RDIS.
1.3. The cases where a new connection for the access to the FTS is installed at the same time the ADSL technology is made available shall not be excluded from the measurement of the present parameter.
1.4. The connection for access to the public telephone network at a fixed location means installing and making effectively available to the client, for the use thereof, a connection between the local switching central or concentrator and the first terminal device for exclusive use of the client, or in alternative, to the client?s network, pursuant to legislation in force regarding telecommunications infrastructure in buildings.
1.5 The measurement of this parameter shall be carried out only as regards the requests for connection which comprise also a network connection and service activation.
1.6. In those cases where a request for installation involves more than one connection for access to the public telephone network at a fixed location, the installation of each one of these connections shall be accounted in separate for the calculation of the parameter
1.7 The measurement of the PQS1 shall not consider:
? The temporary installations, which refer to those the duration of which is of one month at the most;
? The cases where the providing undertaking resorts to third parties? infrastructures (local loop, leased lines) for the supply of the service connection.
2. To measure the quality of service according to the present parameter, providing undertakings shall gather
a) Delay values in the supply of connections corresponding to 95% and 99% percentile values of the swifter installations;
b) Rate of supply requests fulfilled up to the date agreed with the client.
3. Calculation method regarding the information provided for in point a) of the preceding paragraph:
3.1 The calculation of values provided for in point a) of paragraph 2 shall be based on the method comprised in Annex B of the document ETSI EG 201 769-1 v1.1.1 (2000-04).
3.2. The calculation of values provided for in point a) of the paragraph 2 shall disregard the cases where the client defines an aim date, nevertheless, the providing undertaking shall supply, in addition to the present parameter, information on the ratio between the number of initial connections supplied, the client having established an aim date, and the total number of initial connections supplied.
3.3. For the purpose of the preceding paragraph, an aim date is deemed to exist where the established installation date has been requested by the client and is subsequent to the date which results from the application of the value disclosed for the present parameter of quality in the scope of point b) of paragraph 2 of article 7 of the present Regulation.
3.4. The supply time limit shall be considered:
- From the date of reception of the request by the providing undertaking; or
- From the date of amendments/additions to agreements already concluded
3.5. The parameter calculation shall disregard:
- Time imputable to the client that elapses from the moment the providing undertaking is informed or is aware that the premises of the client do not offer conditions for the supply of the connection, up to the moment the referred situation is cleared;
- The delays associated to the installation of the client?s network or to the first terminal device for the client?s exclusive use, pursuant to legislation in force regarding telecommunications infrastructure in buildings, where such installation is not under the responsibility of the providing undertaking.
3.6 The periods between delays imputable to the client, where they exist, are deemed as being under the responsibility of the providing undertaking, and as such, shall be added up for parameter calculation purposes.
3.7. The present parameter concerns all requests for connection fulfilled within the reference period and shall be unbundled, where applicable, by the different types of access:
- Analogue;
- Basic RDIS;
- Primary RDIS;
- Others.
4. Calculation method regarding the information provided for in point b) of paragraph 2:
4.1. The date agreed with the client shall mean
- Any date requested by the client and accepted by the providing undertaking
- Any date set by the providing undertaking and not refused by the client
4.2. In case of postponement of a first date agreed with the client and later setting of a new date for reasons imputable to the providing undertaking, the first date shall be considered for parameter calculation purposes.
4.3. The cases where the client defines an aim date shall be considered for the purpose of calculation of the present parameter.
PQS2 - Fault Rate Per Access Line
1. Definition:
1.1. The QSP2 measures the number of valid fault reports made by users to the services of the providing undertaking, for reasons of disrupted or degraded service attributable to the network of the providing undertaking or any interconnected public network involved in eligible communications2https://www.anacom.pt/render.jsp?contentId=55130 for calculation purposes.
1.2. A valid fault report shall mean:
a) The fault the existence of which is confirmed after a test is made;
b) A fault which disappears when the test is carried out, there being means to prove that it actually took place.
1.3. The measurement of the QSP2 shall not consider fault reports concerning the physical state of public pay phones for the access to the telephone service at a fixed location, but the reports on faults concerning communications made from public pay phones where the disrupted or degraded service is attributable to the network of the providing undertaking of the telephone service at a fixed location shall be considered.
1.4. The services of the providing undertaking shall mean the services intended for the report of faults on the part of clients.
1.5. For each valid report regarding a basic or primary access, only one fault shall be accounted for, regardless of the number of activated channels that have been affected by the fault.
1.6. Until the fault has been repaired by the providing undertaking, the reports on the same access shall be accounted for as a single report.
