If this is an initial installation, the units will require
provisioning to appropriately configure them out of
the factory default states.
2.1 Logon to Total Access system.
2.2 Check to ensure the LTU line cards are
correctly provisioned according to circuit
parameters. Under the Provisioning menu, set
numbered option, Network Source, to G.703.
This option causes the LTU to look to the
individual G.703 backplane connector for its
data feed.
2.3 Ensure the provisioning of both the
MAIN and AUX LTUs is identical,
except for the following options:
a. Provision the MAIN unit to OUT OF
SERVICE-MAINTENANCE (OOS-M)
mode.
b. Provision the AUX unit to the OUT OF
SERVICE-UNASSIGNED (OOS-U) mode.
2.4 Enable protection switching
a. Access the MAIN Menu of the LTU in the
odd-numbered (MAIN) slot.
b. Select Option 7, Protection
Configuration.
c. Select Option 1, Protection Mode.
d. To enable protection switching, select
Option 1, ENABLE.
NOTE
Unless the AUX circuit is in the OOS-U mode,
the operator will not be able to change the
Protection mode of the MAIN LTU.
e. Set Options 2 and 3, BER Threshold and
BER Interval (see Table 3 in the
Installation and Maintenance practice for
definitions).
f. Back out of the menu for the MAIN slot
and access the LTU in the even-numbered
(AUX) slot.
g. Select Option 7, Protection Configuration.
h. Option 1, Protection Mode, will have been
set to AUTO. If you desire to provision a
different H-LSS mode, select Option 1,
and choose between Auto, Manual AUX,
Manual Main, and Auto Hold.
i. Set Options 2-7 as desired on the AUX
unit.
2.5 From the provisioning menu of the AUX
circuit, reset the AUX unit to OOS-M.
2.6 Logoff the system
a. From the Total Access Menu, select
Option 7, Logoff, and press .
b. From the Exit and Logoff screen, select
“Y” and press .
3. INSTALL THE DUAL-SLOT STANDALONE
HOUSING
See the associated Installation and Maintenance
practice, P/N 61245034L2-5, for mounting and wiring
instructions.
4. INSTALL THE NTU
The NTU terminates local loop HDSL signals
originating from the Central Office (CO) unit and
transforms the HDSL signal into traditional G.703
signals to be delivered to the customer.
4.1 Install the NTU into the Dual-Slot
Remote Housing
Electronic modules can be damaged by static
electrical discharge. Before handling modules,
wear an antistatic discharge wrist strap to
prevent damage to electronic components.
Place modules in antistatic packing material
when transporting or storing. When working
on modules, always place them on an
approved antistatic mat that is electrically
grounded.
4.1.1 Connect the individual 4-wire HDSL
circuits to the HDSL terminal block
inside the Dual slot remote housing.
The 4-wire MAIN circuit will connect
to the Loop 1 and Loop 2 terminals
labeled “MAIN” and the 4-wire AUX
circuit will connect to the Loop 1 and
Loop 2 terminals labeled “AUX.”
4.1.2 Gently but firmly push the NTU
into the lower dual slot remote
housing slot. Repeat this step for the
second NTU in the upper slot.
4.1.3 The LTUs will transfer provisioning
data to the NTUs upon power up.
Some provisioning of the NTU,
however, may be necessary due to
hardware DIP switches and jumpers.
See the Installation and Maintenance
practice for the specific NTU utilized
by your company.
