Page 2: Reason For Reissue
This practice has been reissued to revise Section 1C, Features. B. Description The O3-12D1D converts 12 DS1 signals into an OC3 optical signal. By using standard, non-proprietary, virtual tributary (VT1.5) and synchronous transport signal (STS-1) mapping, the O3-12D1D provides fiber- to-fiber compatibility with synchronous optical network (SONET) multiplexers as well as far-end O3-12D1D units. - Page 3 O3-12D1D 1665, Issue 6, April 2013 Table 1 — O3-12D1D Board and OC3 Transceiver Ordering Codes Link Maximum Maximum CLEI™ Wave- Loss Output Input Number Type Ordering Code Code length Budget Level Level of Fibers of Fiber A.

0 to 655 feet as well as 0, 7.5, or 15 dB. The O3-12D1D detects loss of signal, AIS, RAI, and line code violations for each DS1 on the drop side. High levels of bipolar violations (BPVs) are tracked in the craft port as code violations – line level (CV-L). - Page 8 O3-12D1D 1665, Issue 6, April 2013 Table 3 — O3-12D1D Alarm Behavior Alarm Messages Alarm Unit Craft Sent Dropped Stimulus Port Alarm Alarm Toward Applied State Message State Contacts State Contacts OC3 (FE) DS1 (NE) Loss of Power CLOSED CLOSED –...

AIS toward the OC3 or to implement a terminal loopback in which the received DS1 data is looped back toward the OC3. If the AIS option is selected, AIS-CI will be sent only when the O3-12D1D is provisioned as a Remote unit and the AIS-CI option is enabled from the DS1 configuration menu. -
Page 10: Tower Recommendations
1665, Issue 6, April 2013 For Type 5 (EIPP) applications, the O3-12D1D is to be installed in an electronic equipment cabinet (EEC) and have its DS1 ports connected with cabling that does not exceed 1 meter (3.3 feet) in length to Bourns 303M-09H3GH 5-pin or equivalent protectors inserted in an approved 5-pin protector block. -
Page 11: Controls And Indicators
B. Controls and Indicators Front Panel The front panel of the O3-12D1D provides connection to the OC3 and DS1 signals as well as the craft port. LEDs show OC3, DS1, and UNIT status. Front-panel connectors and indicators are shown in... - Page 12 DS1s. Turns OFF to show all DS1 ports are set to disabled. NOTE 1: Use Pulsecom bail-lock to unterminated cable (AMP-MBL/U50Sxxx, where xxx = cable length in feet) OR use Pulsecom bulkhead cable kit (CPM-12DS1X) in 3O3D3-CPL2C installations, or in 2O3D3-19A installations with BP-19/BP-23 rack-mounted bulkhead plates.
- Page 13 Unplugging the card, changing the position of switch S2-1, and plugging the card back in return all parameters to their default values. Note that the initial position of S2-1 is not important; the O3-12D1D detects a change in the position of S2-1 during power-up as an instruction to restore parameters to their default values.

Page 14: Select And Install Mounting
C. Select and Install Mounting Table 7 provides a list of the mountings that should be used with the O3-12D1D. For applications requiring loss-of-power immunity, use redundant power such as that available with the 2O3D3-19A REVB. Use standard hardware to securely attach the mounting to the rack, door, wall, or backboard. See the... - Page 15 NCM1FEEC – Provision for one O3-12D1D; subscriber 24 VDC, local 1649, −48 VDC, Pulsecom 120 VAC to −48 VDC Power Node with Enclosure 1680 battery backup, or Pulsecom Span Power units. A Pulsecom CSSI broadband upgrade kit must be installed in the CP528.

0.75A fuse is properly installed for the mounting slot in use. • If the UNIT indicator is red, verify that the laser transceiver is properly latched into its socket. If the LED remains red, the O3-12D1D module is defective and should be replaced. -
Page 17: Make Oc3 Connections
Procedure 3. Making OC3 Connections STEP ACTION Before plugging in the OC3 fiber, verify that the O3-12D1D front-panel OC3 indicator is red. If the OC3 indicator is off or green, the unit is defective and should be replaced. Remove the protective dust cover from the front-panel OC3 LC jack. -

Page 19: Craft Port
1665, Issue 6, April 2013 5. CRAFT PORT The unit’s craft port provides local and remote access to O3-12D1D operation and provisioning. The craft port can be connected to a terminal emulator to permit network operations center (NOC) access to O3-12D1D provisioning and performance data via TL1 commands (see Pulsecom Practice Section 1639). - Page 20 HyperTerminal as your default telnet program. At the ‘Name:’ prompt in the Connection Description dialog box, type O3-12D1D. Then select an icon that you wish to represent the O3-12D1D to simplify future access.

Although the O3-12D1D (when provisioned for Remote operation) has a default TID of PULSECOM2, a unique TID should be assigned to each O3-12D1D when these units are used in the integrated mode as part of a larger network. - Page 23 DS1 Loopback Timeout 1, 2, 4, 8, 60 minutes, or No TimeOut 60 minutes* Response to DS1 Loss of Send AIS to OC3 (i.e., toward the CO when the O3-12D1D is at the subscriber Send AIS (or Signal site) or initiate loopback...
- Page 24 DCC TL1 commands.) To respond to DS1 loopbacks, the O3-12D1D must be provisioned as a Remote (CPE-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 O3-12D1D will respond to either in-band or ESF data link (out-of-band) loopback codes;...
