Chapter1 Hardware Installation
Alarm, Timing, LAN, and Craft Pin Connections
Note Refer to Telcordia SR-NWT-002224 for rules about provisioning timing references

Procedure: Install Timing Wires on the Backplane

Step 1 Use #22 or #24 AWG wire.
Step 2 Wrap the clock wires on the appropriate wire-wrap pins according to local site practice.
Step 3 The BITS pin field (FG1) has a frame ground pin beneath it. Wrap the groun d shield of the alarm cable
to the frame ground pin.
Note For more detailed information about timing, see the “Setting Up ONS 15454 Timing” section
on page 3-12.
1.9.3 LAN Installation
Use the LAN pins on the ONS 15454 backplane to connect the ONS 15454 to a workstation or Ethernet
LAN, or to a LAN modem for remote access to the node. You can also use the LAN port on the TCC+
faceplate to connect a workstation or to connect the ONS 15454 to the network. Table 1 -3 shows the
LAN pin assignments.
Before you can connect an ONS 15454 to other ONS 15454s or to a LAN, you must change the default
IP address that is shipped with each ONS 15454 (192.1.0.2) . See t he “Change IP Address, Default
Router, and Network Mask Using the LCD” procedure on page 3-4.
