ADTRAN 3060 Reset ALL Equipment to Operating Condition, Disabling Protection Switching

4.1.4Upon provisioning of the NTUs, the faceplate LEDs should read as shown in Table 1.

NOTE

The condition of the ALM, G.703 and G.703 LEDs depends upon the status of the equipment on the ends of the installed circuit. If both terminations of the circuit are appropriately configured and prepared to pass data, the LTU ALM LEDs will be out, the LTU G.703 LEDs will be green (MAIN) and Off (AUX), the MAIN NTU G.703 LED will be green and ALM off, while the AUX NTU G.703 will be off, and ALM red.

5.RESET ALL EQUIPMENT TO OPERATING CONDITION

When the customers at both ends of the circuit have turned up their equipment and are running data (or test patterns, or are in loopbacks, or some other condition that will preclude the generation of alarms), the LTUs can be placed In Service to restore the alarm generating functions of the equipment to the network.

5.1From the Total Access 3010 LTU Provisioning Screen for both the MAIN and AUX LTUs, select the Service State option, and place both LTUs In Service.

NOTE

Placing the LTUs In Service will change the PWR LED from slow flashing green to steady green.

6. DISABLING PROTECTION SWITCHING

Disabling the protection switching mode from the circuit converts both the MAIN and AUX circuits into independent standalone HDSL circuits.

CAUTION

Ensure that data has been removed from the AUX circuit before proceeding with the next step. Disabling PROTECTION SWITCHING before removing data from the AUX Loop will cause a loss of signal condition on that loop. Under normal circumstances, the data on the HLSS circuit will be running on the MAIN HDSL circuit, and this precaution is unnecessary.

6.1Disabling Protection Switching

a.Access the AUX LTU and select Option 2, Provisioning, from the HDSL Main Menu.

b.From the Provisioning menu, choose the Service State option.

c.Select Option 3, Out Of Service-Unassigned.

d.Escape out of the AUX LTU menus and proceed to the MAIN LTU menu.

e.From the Main Menu, select Option 7, Protection Configuration.

f.From the Protection Configuration menu, select Option 1, Protection Mode.

g.Choose Option 2, Disable.

NOTE

There is no provisioning required at the NTUs to remove protection-switching capability. Upon completion of the above procedure, the MAIN circuit is an independent, non-protected HDSL circuit. The AUX circuit is also now independent, with protection switching disabled, and currently OOS-U.

6.2Adjust Wiring at Dual Remote Housing

Once protection switching has been disabled in the LTUs, the housing is internally wired to provide a G.703 signal to both the MAIN G.703 and AUXILIARY/TEST G.703 RJ-48 jacks. Connect the customer’s equipment to the AUX RJ-48 jack or the AUX G.703 terminal strip in the housing to complete a second independent HDSL circuit.
