  • Page 8: Installation

    4. INSTALLATION DANGER The O3-4D1B employs Class 1 laser products. To avoid injury, do not look directly into the optical transceiver or into the fiber cable. Note that the light is invisible; the optical signal cannot be detected by the eye.
  • Page 9: Controls And Indicators

    A. Controls and Indicators Front Panel The front panel of the O3-4D1B provides connection to the OC3 and DS1 signals as well as the craft port. LEDs show OC3, DS1, and UNIT status. A 4-position DIP switch enables or disables each DS1. Front-panel controls and indicators are shown in Figure 1 and described in Table 4.
  • Page 10 Bulkhead Cable Kit - If desired, order CPM-4DS1X for use in the 3O3D3-CPL2C locking wall-mounted enclosure. Each kit provides four bulkhead-mounted RJ48C DS1 jacks and a cable that connects these jacks to the O3-4D1B front-panel connector. See Practice Section 1633 for wiring information.

  • Page 23: Performance Monitoring

    O3-4D1B 1659, Issue 3, January 2011 To respond to DS1 loopbacks, the O3-4D1B must be provisioned as an RT (subscriber- side) unit (default), have its loopbacks enabled (also default), and be provisioned for either ESF (default) or SF operation. When provisioned for ESF operation, the O3-4D1B will respond to either in-band or ESF data link (out-of-band) loopback codes;...

  • Page 29: Maintenance

    In case of equipment malfunction, check the front-panel indicators. Reference Table 4. Since O3-4D1B and O3-4D1L3B units are used to extend DS1 circuits, they pass on network timing. As a result, standard T1 test sets might need to be provisioned for INTERNAL timing rather than Loop timing, as shown in Figure 8.

    1659, Issue 3, January 2011 9. CUSTOMER SERVICE Direct questions concerning the operation of the unit to Pulsecom Technical Support. If the unit is defective, limit field repair to replacement of the plug-in module or SFP transceiver. Obtain repair services by returning the defective unit to the Pulsecom Repair Department, 400 E.
