    “Introduction” section of this manual. Description This section should be performed on all rear access DDM-2000 OC-12 Multiplexer shelf installations. For front access Multiplexer shelf installations, refer to the “Equipment and Front Access Installation for DDM-2000 OC-12 Multiplexer” section of this manual.

  • Page 66: Tools, Test Sets, And Accessories

    All of the cables, except power and the optical fibers, are connected to the DDM-2000 OC-12 backplane. It is a requirement that the DDM-2000 OC-12 Multiplexer be equipped with a pro- tective backplane cover at the completion of the installation.

  • Page 67: Planning

    DDM-2000 OC-12 Fan Shelf 4.0 inches Each DDM-2000 OC-12 shelf installed must have an air gap of at least 3.0 inches between the bottom of the DDM-2000 OC-12 shelf and the equipment (or bay frame if the shelf is installed at the bottom of the bay).

  • Page 68: Inspection

    Perform the following procedure before the DDM-2000 OC-12 Multiplexer installation or cable installation. Procedure (1) Verify that the frame or structure into which the DDM-2000 OC-12 Multiplexer will be installed is properly grounded. NOTE: Each DDM-2000 OC-12 shelf, heat baffle, and fan shelf comes equipped with a pouch, attached to the shelf (or baffle), containing the hardware required for mounting and grounding and an installation kit.

  • Page 69: Equipment Installation

    (3) Inspect the DDM-2000 OC-12 shelf for visible damage including bent or touch- ing backplane pins. (4) Determine the type of bay frame the DDM-2000 OC-12 shelf will mount in. Reposition the DDM-2000 OC-12 shelf side mounting brackets, if necessary.

  • Page 70: Procedure

    Equipment and Rear Access Cabling for the DDM-2000 OC-12 Multiplexer Procedure (1) Mount the DDM-2000 OC-12 shelves, fan shelves, and heat baffles in a network bay frame with the wide flange of the bay frame to the front as shown in Figure 2-5 on page 2-52.

  • Page 71: Ds3 Cabling - Rear Access

    (5) Locate the filter provided with the fan shelf. Install the filter up against the bot- tom of the DDM-2000 OC-12 shelf located directly below this fan shelf per Fig- ure 2-9 on page 2-56.

  • Page 72: Procedure

    Figure 2-10 on page 2-57. (2) Route the cables out of the DDM-2000 OC-12 bay per Figure 2-10 on page 2- 57, stacking the cables as shown in Figure 2-2 on page 2-49 or Figure 2-3 on page 2-50.

    363-206-208 Equipment and Rear Access Cabling for the DDM-2000 OC-12 Multiplexer (3) Dress and tie the cables as close to the DDM-2000 OC-12 backplane as possi- ble without touching any backplane pins. (4) Unless the cables are Group 126 (D.A.) or 136 (D.A.), route and connect the cables along the cable rack and into the terminating equipment bay.

  • Page 74: Procedure

    PVC tubing, when running the cable from the DDM-2000 OC-12 to the cable rack. The fibers should be placed in the cable rack in a protective channel with nothing on top of them. DO NOT use cable ties with the optical fiber cables.

  • Page 75: Oc-3/Oc-12 Bay Fiber Connections

    (4) Label the optical fiber cables, indicating bay, shelf, pack, and direction (IN or OUT). (5) Remove the fiber tray cover from the bottom front of the DDM-2000 OC-12 shelf. This cover is attached to the fiber tray with three screws.

  • Page 76: Power Cabling - Rear Access

    (1) Obtain either a single shelf power cable or a bay power cable. The bay power cable is configured to power up to three DDM-2000 OC-12 shelves and up to three fan shelves. Refer to Table 2-7 on page 2-40.
  • Page 77 WARNING: Verify that the breakers are off or that the BDFB fuses are not installed. (5) Splice feeders from the BDFB to the DDM-2000 OC-12 Multiplexer power cable. NOTE: Four cables are spliced to each power cable: BAT A, BAT A RTN, BAT B, and BAT B RTN.

In performance monitoring, the count of seconds (1) in which a signal is declared failed or, (2) in which, 10 consecutively severely errored seconds (SES) occurred, until the time when 10 consecutive non-SES occur. Unidirectional A protection switching mode in which the system at each end of an optical span moni- tors both service and protection lines and independently chooses the best signal...

Seven VT groups (756 bytes) are byte-inter- leaved within the VT-organized STS-1 synchronous payload envelope. Zero Code Suppression A technique used to reduce the number of consecutive zeros in a line codes signal (B3ZS for DS3 signals and B8ZS for DS1 signals).
