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.

2.1.2Ensure 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.

2.1.3Ensure 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

2.1.2above 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.
