1. UNPACK AND INSPECT THE THE TOTAL
ACCESS DS3 MUX MODULES
Each DS3 MUX Module is shipped in its own
cardboard shipping carton. Open the carton carefully
and avoid puncturing the carton with sharp objects.
After removing the unit from the carton, unwrap the
antistatic bubble-wrap and pull the unit from the
protective plastic bag.
After unpacking the unit, inspect it for damage. If
damage is discovered, file a claim with the carrier,
then contact ADTRAN. See Warranty and Customer
Service.
2. INSTALL THE DS3 MUX MODULES
2.1. Install the DS3 MUX Module into Total
Access 3010. 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.
The procedure below assumes that the DS3
MUX is being newly installed into the Total
Access 3010. If the MUX is already up and
running, begin with Step 2.1.2.
2.1.1. Gently but firmly push the DS3 MUX
into the second slot, slot A, at the left
end of the shelf. Simultaneous thumb
pressure at the top (above the POWER
LED) and bottom (below the Test/
Enable button) of the unit will ensure a
good seat of the DS3 pins into the
backplane connector. Push the ejector
tab up and closed against the DS3 `
faceplate.
2.1.2 Ensure that MUX A is in the Out of
Service-Maintenance (OOS-M)
mode. Placing the MUX in OOS-M
will prevent the MUX from
generating alarms back to the
network, and will allow loopbacks to
be initiated and taken down. Data
traffic on other embedded G.703
circuits will not be disturbed. Note
that while the DS3 MUX is in the
OOS-M mode, no alarms will be
passed to the network, including those
of circuits that may already be in
service on the MUX. After the APS
circuit is turned up, be sure to reset the
MUX to the In Service (IS) mode as
indicated in Step 6.0.1 to regain alarm
notification.
NOTE
If a single multiplexer module is used, skip Step
2.1.3. For redundant MUX applications, continue
with 2.1.3 below. When using a single
multiplexer, disregard all references to the
Offline MUX.
2.1.3 Ensure that Linked Provisioning is
“Enabled” on MUX A, and install the
second MUX in Slot B of the Total
Access 3010, using Steps 2.1.1 and
2.1.2 above for the B slot MUX. This
will allow MUX B to be configured as
MUX A when MUX B is installed.
Linked Provisioning is factory
defaulted to Enable, however, Linked
Provisioning does not affect Service
States. The factory default Service
State for MUX B is Out of
Service-Unassigned. Both muxes are
now to be configured identically, and
in the OOS-M service state. At this
point, faceplate LED indicators for
MUX A (Online) and MUX B
(Offline) will be as in Table B-1.
