NOTE
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 H-LSS
circuit will be running on the MAIN HDSL
circuit, and this precaution is unnecessary.
7.0.1 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.
7.0.2 Adjust wiring at Dual remote housing.
Once protection switching has been
disabled in the LTUs, the housing is
internally wired to provide an E1signal
to both the MAIN E1 and
AUXILIARY/TEST E1 RJ-48 jacks.
Connect the customer’s equipment to
the AUX RJ-48 jack or the AUX E1
terminal strip in the housing to
complete a second independent HDSL
circuit.
NOTE
G.703 DS3 multiplexer channel mapping to the
even-numbered (formerly AUX) slot in the Total
Access 3010 chassis will not automatically be
restored. Assignment of an embedded G.703 in
the DS3 data stream to the even slot will have to
be made prior to using the slot as a DS3-fed
HDSL circuit.
