In place of the Minister of Economics, Minister of health of the Ministry of economy Guntis Belēvič submitted version of annex 3 to the Latvian et seq LBN 262-15 "electronic communications networks" (approved by Cabinet of Ministers of 30 June 2015 regulations No 328) for electronic communications networks and electronic communications services at 1. this annex provides for electronic communications networks and electronic communications services in the management of construction. 1. the first sample 2. First sample provides a variety of management options, on the basis of the private apartment house, which also contains office space. 3. the owner of the House is built by your electronic communication network, which is possible in the management of property in one of the following: 3.1 cable sewers (12); 3.2. coupling or cable loop, which is sufficiently long to be assembled into the sleeve (13), if necessary. 4. service frontier post between electronic communications services or of public electronic communication (PES) operator (or the providers of electronic communications services) according to the specific situation can be point 1, 2, 3, 4, 5, 6, 10, 13.

2. the second sample second sample 5 different reference points provided in the variations, where land ownership has built more buildings. 6. property management is possible in one of the following: 6.1 cable sewers (5); 6.2. the sleeve or cable loop, which is sufficiently long to allow the assembled CAP, if it is required (6). 7. service frontier post between users of electronic communications services and pest operator (or the providers of electronic communications services) according to the specific situation can be point 1, 2, 3, 5, 6.

3. the third model of the third model provides 8 different variants of the frontier, if more land is built on shipbuilding, which access is provided to the public electronic communications network, using pest operator ducts. 9. property management is possible in one of the following: 9.1 cable sewers (4); 9.2. the sleeve or cable loop, which is sufficiently long to allow the assembled CAP, if it is necessary. 10. service frontier post between users of electronic communications services and pest operator (or the providers of electronic communications services) according to the specific situation in point can be 2, 3, 4, 7.

4. the fourth sample 11. Fourth, various reference points provided in the sample choices, if more land is built on shipbuilding, which access is provided to the public electronic communications network, using pest operator hanging cable line. 12. property management is external distribution box (1) or an external installation cable closet (4). 13. service frontier post between users of electronic communications services and pest operator (or the providers of electronic communications services) according to the specific situation can be point 1, 2, 3, 4.

5. The fifth sample 14. Fifth sample provides various exit options, unless the land is built more buildings, which access is provided to the public electronic communications network, using wireless transmission system of subscribers. 15. property management is an external or an indoor distribution box (3). 16. service frontier post between users of electronic communications services and pest operator (or the providers of electronic communications services) according to the specific situation in paragraph 2 may be, 3. The Minister of economy in place, Minister of health of the Ministry of economy Guntis Belēvič submitted version of annex 4 to the Latvian et seq LBN 262-15 "electronic communication networks (approved by Cabinet of Ministers of 30 June 2015 regulations No 328) cable sewer available capacity determination methodology set out in this annex 1. How to calculate the available capacity of the ducts.
2. the available capacity of the ducts of the dp is calculated by the following formulas1: where D is the cable drain pipes internal diameter, someone needs to pull the cable with diameter dp, if there are n cables with diameters from d1 to DNA; K is a coefficient that is chosen according to table 1 of this annex the conditions shown. Mathematically transforming the cable drain available capacity the dp calculation formula gives a formula for the calculation of cable sewer pipe inner diameter (D), someone needs to pull the cable with diameter dp, if there are n cables with diameters of up to dn: where D is the cable drain pipes internal diameter, someone needs to pull the cable with diameter dp, if there are n cables with diameters from d1 to DNA; K is a coefficient that is chosen according to table 1 of this annex the conditions shown. 3. in paragraph 2 of this annex that calculations do not apply as criteria for cables of cable electrification sewerage stage with the bend, the branches and the pipe where the cables put with iepūšan technology. Note the. 1Vis diameter of the formulas in mm with an accuracy of one decimal decimal place; n is a natural number. table 1.
