61182007L1-5A Section 61182007L1-5, Issue 1 A-3
4.1.4 Upon 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.
5.1 From 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.
6.1 Disabling 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.
6.2 Adjust 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.
