1 Professional Engineer Authenticated TELUS Residential Service Conduit Requirements For Stand-Alone Homes and Duplexes in Fibre Only Communities Beginning in January 2010 TELUS began designing new subdivisions within the Top 48 population centres in Alberta and British Columbia using only fibre optic cable. This document explains the new conduit only servicing model that is used in fibre only communities, and it summarizes what the TELUS and builder responsibilities are within that model. For more information please contact the following TELUS personnel: 780 Area Code / Red Deer North Rick Fedirko rick.fedirko@telus.com 403 Area Code / Red Deer South Tony Walker tony.walker@telus.com General Entrance Requirements TELUS extends the 20mm (3/4 ) HDPE conduit which is stubbed at the property line to the service connection point on the side of the home. TELUS will use this HDPE or PVC conduit and the builder provided PVC conduit and LB to install fibre optic cable when a customer orders service. Note that TELUS no longer pre-installs cables to homes in fibre only communities, and that we are requesting an empty conduit within the house. If a coiled drop of cable is located at the property line then please follow the information included in the P630 located at: Page 1 of 10

2 Fibre Only Conduit Service Diagram: TELUS Responsibility After the builder contacts Ledcor (see Builder Responsibilities below), a continuous section of 20mm (3/4 ) HDPE (high density polyethylene) SDR 13.5 orange or PVC service conduit will be extended from the property line to the side of the house at TELUS expense. At the base of the foundation wall the HDPE or PVC conduit will be fed through a TELUS supplied rigid sweeping 90 degree bend (to prevent HDPE kinking) and extended up the wall through the builder provided PVC conduit and LB. The HDPE conduit will be capped off within the LB. Builder Responsibilities TELUS requests the builder do the following in order to accommodate the HDPE or PVC conduit: 1. TRENCH: Provide a suitable trench from the property line to the service location at the side of the house as follows: Trench must be free of construction materials, rocks or stones. Trench must be sloped for grade changes. Stepped grade changes are not acceptable as this can cause pinching or constriction of the HDPE conduit. Page 2 of 10

3 Where communications services and power services share a common trench, Canadian Electrical Code rule must be followed. 2. PVC CONDUIT & LB: Supply and install a 32mm (1-1/4 ) LB and a 32mm (1-1/4 ) schedule 40 PVC conduit along the outside of the house from the LB to a minimum of 300mm below the finished grade. The TELUS provided HDPE or PVC conduit pathway will be installed inside the PVC conduit and LB, and. *Note that if the HDPE is installed before the builder supplied PVC conduit, then the builder should slide the schedule 40 PVC conduit over the TELUS supplied HDPE leaving the top of the HDPE conduit accessible inside the LB. Provide the following separations between services on the outside of the house: Between Electrical service and TELUS service: 200mm (8 ) minimum separation Between Cable TV service and TELUS service: 250mm (10 ) minimum separation 3. ARRANGE TELUS CONDUIT: After excavation of the trench and installation of the schedule 40 PVC conduit and LB, the builder shall contact the TELUS contractor (Ledcor Technical Services, LTS) to arrange for extension of the HDPE conduit from the property line to the side of the house at TELUS expense. Note that LTS will arrange to install the HDPE or PVC conduit with 72 hours of being contacted, so do not back-fill the trench until the conduit extension has been completed. LTS contact information as follows: Phone (toll free, no area code required) to ltsconduitextension@ledcor.com and provide address and contact information 4. INTERNAL CONDUIT PATHWAY: Supply and install a 25mm (1 ) non-metallic conduit from the LB to the central wiring location inside the home, to provide TELUS with a continuous pathway from our pedestal to the central wiring point within the house. This conduit should have a maximum of four sweeping 90 degree bends, and should have a pull string installed. Providing an internal conduit pathway means that no external splice box is required which makes the external installation more visually appealing and matches the typical installation method of other service providers. *Note that this empty conduit is instead of the previously supplied 4 pair 24 gauge telephone wire and the 6 gauge insulated ground conductor. 5. BACKFILL: Backfill the service trench after the TELUS HDPE or PVC service conduit is installed. Ensure the trench is free of construction material and the service conduit is placed so that kinking or pinching will be avoided. Use only native loose packed fill directly on the service conduit and avoid large rocks or frozen soil which could damage the conduit. Ensure there is 500mm (20 ) of fill coverage on top of the service conduit before tamping. 6. NO INTERNAL CONDUIT PATHWAY: If the builder decides not to provide a non-metallic conduit between the LB and the central wiring point inside the home, then TELUS requires the builder to supply and install a bend insensitive fibre (ITU-T-G657 compliant, indoor or outdoor rated) a 4 pair 24 gauge telephone wire and the 6 gauge insulated ground conductor between the external LB and the internal central wiring point leaving 2m of slack at each end. This will result in an additional splice box installed on the LB on the outside of the house. This wiring is required because TELUS cannot guarantee that fibre could be installed between the LB and the central wiring point through a finished basement at some time in the future. Page 3 of 10

4 Normal Conduit Routing to Central Wiring Location: TELUS' primary requirement is to have a clear and unobstructed raceway from the outside wall to the panel location. TELUS' conduit must come above grade at the side of the house and cannot be placed as a continuous underground run with direct entry into the basement for two specific reasons: In the event that the street or pedestal location was too flooded the conduit could act as a direct route for the water to enter into the house. In the event the duct is damaged on private property TELUS would have no direct access into the house to provide temporary services. Internal Conduit Routing Options for a Centralized Panel Extend conduit through the basement floor: Alternative Routing for Centralized Panel Builder Supplied: 1 ¼ Schedule 40 Rigid Conduit to 300mm below grade 6 x 6 or Approximate Transition Box with Cover in place of STB 1 Schedule 40 Rigid duct to sweeping 90 extended through footing to Centralized Panel Location Minimum 900mm Coverage To Property Line Line of Grade 1 ¼ Sched 40 Rigid Conduit Min 300mm Below grade Extend Pull rope 1 Sched 40 Rigid Conduit To Centralized Panel Foundation Wall TELUS Supplied: Continuous 20mm HDPE SDR 13.5 Conduit 2 Sweeping 90 PVC Schedule 40 *Note all bends must be Sweeping* Page 4 of 10

6 Outside To Inside Transition Pre-Wire and Panel/Backboard Area Central Wiring Requirements The inside wiring should be done in a star configuration where the individual set runs from each telephone jack and TV location collect at a common location within the home (see Figure 2). The centre of the star is to be in a heated environment where there is no risk of the ambient air temperature falling below 0º (zero) Celsius. A garage is NOT a suitable location Builder/Owner will provide One (1) duplex 15A non-switched power receptacle dedicated to home networking, communication and entertainment equipment, installed in a multi media enclosure at this location (the use of a Multi Media enclosure or Smart Panel is not mandatory although it is recommended). Total space required for the mounting of the Fibre Equipment and Multi Media enclosure will be a minimum of 600mm (24 ) x 900mm (36 ). Owner/Builder will provide patch panels for Voice / DATA / Coax. Refer to Figure 2 and Figure 3 for more information Page 6 of 10

8 Inside Wiring and Equipment Layout (Figure 3) 24 X 36 area of wall space required to accommodate all equipment. If a Multimedia enclosure is not used the same layout will apply on a securely fastened ¾ plywood backboard. Page 8 of 10

9 Inside Wiring Instructions The builder/owner shall supply telephone cabling and terminate as follows: Voice, Data and Coax Patch Panel Style Termination strips at the backboard location. All CAT5e inside wire to each location where the Home Builder/Owner would like Voice, DATA and TV (i.e.: if all 3 services are required in one location, then 3 CAT5e would be required at this location). Voice set runs to have W/BL, W/O AND W/GR terminated on RJ11 wall outlets and all 4 pairs terminated at the backboard location on the voice module. Data & TV runs to be terminated on RJ45 wall outlets and all 4 pairs terminated at the backboard location on the Data module according to the TIA-568A standard and labeled at both ends. Verification testing to be completed on all set runs. TELUS prefers using CAT5e cable for TV but can use coax cables.
