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 ground 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 the

“Change IP Address, Default

Router, and Network Mask Using the LCD” procedure on page 3-4
