• how do i find the specifications for "where to install the Qwest telephone Service Network Interface (SNI) box" for new residential telephone service in Tucson, Az?

• Answer:

  Dear tucson-ga, It is not the customer's responsibility to install a Service Network Interface. The service provider, in your case Qwest, must install the SNI at the demarcation point of the residence. "Qwest will provide a Standard Network Interface (SNI) or a registration jack at the demarcation point - the authorized access point for connection to the Qwest network. The SNI is mounted in a visible and accessible location. "The demarcation point will be placed within 12 inches (or a similarly reasonable distance) of the protector or regulated facility in accordance with Qwest policy and FCC docket 88-57." Qwest: Wholesale: Public Access Lines: Provisioning and Installation http://www.qwest.com/wholesale/pcat/resalepal.html#pro As for the demarcation point, the Federal Communications Commission (FCC) mandates that it be located within 30 cm of the protector owned by the service provider or at the minimum point of entry (MPOE), depending on circumstances. Note especially that your service provider, Qwest, must "make available information on the location of the demarcation point within ten business days of a request from the premises owner." If Qwest fails to do so, then "the premises owner may presume the demarcation point to be at the MPOE," which is defined as "the closest practicable point to where the wiring crosses a property line or the closest practicable point to where the wiring enters a multiunit building or buildings." " (a) Facilities at the demarcation point. Carrier-installed facilities at, or constituting, the demarcation point shall consist of wire or a jack conforming to the technical criteria published by the Administrative Council for Terminal Attachments. (b) Minimum point of entry. The ``minimum point of entry'' (MPOE) as used herein shall be either the closest practicable point to where the wiring crosses a property line or the closest practicable point to where the wiring enters a multiunit building or buildings. The reasonable and nondiscriminatory standard operating practices of the provider of wireline telecommunications services shall determine which shall apply. The provider of wireline telecommunications services is not precluded from establishing reasonable classifications of multiunit premises for purposes of determining which shall apply. Multiunit premises include, but are not limited to, residential, commercial, shopping center and campus situations. (c) Single unit installations. For single unit installations existing as of August 13, 1990, and installations installed after that date the demarcation point shall be a point within 30 cm (12 in) of the protector or, where there is no protector, within 30 cm (12 in) of where the telephone wire enters the customer's premises, or as close thereto as practicable. (d) Multiunit installations. (1) In multiunit premises existing as of August 13, 1990, the demarcation point shall be determined in accordance with the local carrier's reasonable and non-discriminatory standard operating practices. Provided, however, that where there are multiple demarcation points within the multiunit premises, a demarcation point for a customer shall not be further inside the customer's premises than a point twelve inches from where the wiring enters the customer's premises, or as close thereto as practicable. (2) In multiunit premises in which wiring is installed, including major additions or rearrangements of wiring existing prior to that date, the provider of wireline telecommunications may place the demarcation point at the minimum point of entry (MPOE). If the provider of wireline telecommunications services does not elect to establish a practice of placing the demarcation point at the minimum point of entry, the multiunit premises owner shall determine the location of the demarcation point or points. The multiunit premises owner shall determine whether there shall be a single demarcation point location for all customers or separate such locations for each customer. Provided, however, that where there are multiple demarcation points within the multiunit premises, a demarcation point for a customer shall not be further inside the customer's premises than a point 30 cm (12 in) from where the wiring enters the customer's premises, or as close thereto as practicable. At the time of installation, the provider of wireline telecommunications services shall fully inform the premises owner of its options and rights regarding the placement of the demarcation point or points and shall not attempt to unduly influence that decision for the purpose of obstructing competitive entry. (3) In any multiunit premises where the demarcation point is not already at the MPOE, the provider of wireline telecommunications services must comply with a request from the premises owner to relocate the demarcation point to the MPOE. The provider of wireline telecommunications services must negotiate terms in good faith and complete the negotiations within forty-five days from said request. Premises owners may file complaints with the Commission for resolution of allegations of bad faith bargaining by provider of wireline telecommunications services. See 47 U.S.C. 208; 47 CFR 1.720 through 1.736 (1999). (4) The provider of wireline telecommunications services shall make available information on the location of the demarcation point within ten business days of a request from the premises owner. If the provider of wireline telecommunications services does not provide the information within that time, the premises owner may presume the demarcation point to be at the MPOE. Notwithstanding the provisions of Sec. 68.110(c) of this part, provider of wireline telecommunications services must make this information freely available to the requesting premises owner. (5) In multiunit premises with more than one customer, the premises owner may adopt a policy restricting a customer's access to wiring on the premises to only that wiring located in the customer's individual unit that serves only that particular customer." Hallikainen: FCC Rules: FCC 68.105 http://kauko.hallikainen.org/FCC/FccRules/2003/68/105/ Furthermore, note that the customer's responsibility extends only to the wiring that leads from the demarcation point to the premises. The SNI and all equipment beyond it, including the protector, belongs to Qwest. "The subscriber and/or premises owner may install wiring on the subscriber's side of the demarcation point, and may remove, reconfigure, and rearrange wiring on that side of the demarcation point including wiring and wiring that may have been installed by the carrier. The customer or premises owner may not access carrier wiring and facilities on the carrier's side of the demarcation point. Customers may not access the protector installed by the provider of wireline telecommunications. All plugs and jacks used in connection with inside wiring shall conform to the published technical criteria of the Administrative Council for Terminal Attachments. In multiunit premises with more than one customer, the premises owner may adopt a policy restricting a customer's access to wiring on the premises to only that wiring located in the customer's individual unit wiring that serves only that particular customer." Hallikainen: FCC Rules: FCC 68.213 http://kauko.hallikainen.org/FCC/FccRules/2003/68/213/ To recapitulate, the SNI is not the customer's responsibility. The service provider, Qwest, must install the SNI at the demarcation point for the residence. As per federal regulations, the demarcation point must be located within 30 cm of the Qwest protector or of the point where the telephone wire crosses the property line. The customer may not tamper with the SNI or with any other equipment on the service provider's side of the demarcation point. For further details, consult the documents containing the above excerpts.
