  • Page 21: Pre-Provisioning-Hdsl Lines

    Revision 01 May 30, 1997 Section 363-718-104 6. Pre-Provisioning—HDSL Lines The HDSL transmission scheme uses two pairs between the COT and the Remote Terminal (RT). The wire pairs should have identical electrical make-ups. Keep exposure to crosstalk and the differences in total wire length, wire gauge, bridge taps to a minimum. Pair isolation (Tip-Ring, Tip-Ground, and Ring-Ground) must be ≥...

  • Page 22: Mounting

    Section 363-718-104 Mya 30, 1997 Revision 01 7. Mounting The COT shelf mounts in a standard 19- or 23-inch CO equipment bay. Use rack adapters when installing onto a 23-inch frame or reverse the mounting bracket (short flange against the shelf) to fit into the 23 inch frame.
  • Page 23 Revision 01 May 30, 1997 Section 363-718-104 Figure 4. Connecting the Frame Ground Use 12 AWG or larger wire (or multiple wires of a smaller gauge) to ensure good power connections to PG-Flex. Connect the CO battery (Figure 5): Connect wires used for the CO battery and the CO battery return to TB1 (-48 Vdc) and TB2 (BATT RTN) screw terminals.
  • Page 24 Section 363-718-104 Mya 30, 1997 Revision 01 HDSL Lines. Connect the HDSL lines (Figure 6): For System 1 installation: Connect the HDSL Pair #1 on System 1 onto wire-wrap pins HDSL_1_T1 (Tip) and HDSL_1_R1 (Ring) on the COT shelf. Connect the HDSL Pair #2 on System 1 onto wire-wrap pins HDSL_1_T2 (Tip) and HDSL_1_R2 (Ring) on the COT shelf.
  • Page 25 Revision 01 May 30, 1997 Section 363-718-104 Bypass Pairs. If subscriber drop testing is required, connect the metallic bypass pairs (Figure 7): Metallic bypass pairs can not be shared between PG-Flex systems or to other digital loop carrier (DLC) systems. For System 1 installation, connect the metallic bypass pair from the main distribution frame (MDF) to wire wrap posts BYPASS_T and BYPASS_R on the COT shelf.
  • Page 26 Section 363-718-104 Mya 30, 1997 Revision 01 Composite Clock. When required, connect the composite clock (Figure 8). You can cascade the composite clock to other PG-Flex shelves. When cascading the composite clock to other PG-Flex shelves, terminate only on the last shelf in the cascade. Connect the primary composite clock leads from the master clock source in the CO to CC1_TIP and CC1_RING termination pins on the backplane.

  • Page 27: Turn-Up And Testing

    Revision 01 May 30, 1997 Section 363-718-104 Subscriber Lines. Connect the subscriber lines: You must use the cable adapter (PN 120-1111-01) to ensure the subscriber terminations follow the information shown in Tables 14 and 15. For PG-Flex system 1, use Table 14 to connect the CO switch cables to the cable adapters for P1 and P3 terminations.
