a) Slide the coupling sleeve of the coaxial cable backward. See diagram1 of
M6 Shelf Dimensions for an ETSI Rack Configuration, on page 275
b) Connect the cable to the ECU module connector. See diagram2 of
Figure 174: Cisco ONS 15454 M6
Shelf Dimensions for an ETSI Rack Configuration, on page 275
.
c) Slide the coupling sleeve forward to lock the cable connector to the ECU module connector. See diagram3
of
Figure 174: Cisco ONS 15454 M6 Shelf Dimensions for an ETSI Rack Configuration, on page 275
.
To unlock the cable connector from the ECU module connector, hold the connector and slide
the coupling sleeve backward. See diagram4 of
Figure 174: Cisco ONS 15454 M6 Shelf
Dimensions for an ETSI Rack Configuration, on page 275
Note
Figure 276: Sequence to Attach the Connectors
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.
Note
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 405
. Repeat for each cable.
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).
