DLP-G298 Install LAN Wires in ONS 15454 M6
a) Slide the coupling sleeve of the coaxial cable backward. See diagram1 of
M6 Shelf Dimensions for an ETSI Rack Configuration, on page
b) Connect the cable to the ECU module connector. See diagram2 of
Shelf Dimensions for an ETSI Rack Configuration, on page
c) Slide the coupling sleeve forward to lock the cable connector to the ECU module connector. See diagram3

Step 3
Connect the other end of the cable to the external source of the timing signal according to
module Pin Assignments - ETSI, on page
Step 4
Change the timing input to high-impedance (lesser or greater than 3 ohms) using a jumper on the ECU module.
Remove the P1 jumper of the BITS-1 to change the top timing input, and the P2 Jumper of the BITS-2 to
change the bottom timing input. Refer to ITU-T G.813 for rules about provisioning timing references.
Step 5 Return to your originating procedure (NTP).

To unlock the cable connector from the ECU module connector, hold the connector and slide
the coupling sleeve backward. See diagram4 of
Dimensions for an ETSI Rack Configuration, on page
The ECU modules provides 1.0/2.3 miniature coaxial connectors used for timing input and
output. The top connectors are for "A" (BITS-1) timing, and the bottom connectors are for "B"
(BITS-2) timing. In each case, the left connector is the input and the right connector is the
output. The input connectors for timing provide a 75-ohm termination.
This task installs LAN wires on the ECU module of the ONS 15454 M6.
