Perform Steps Below in the Order Listed
Assigning the incorrect embedded DSX-1 from the DS3 to a slot in the Total
Access 3000 could disrupt existing traffic.
4. APS configuration of the DS3 MUX units is NOT required for the HTU-Cs to be
in HLSS configuration. The two APS configurations operate independently of
each other. If APS is desired on the MUX units, please see DLP-725, MUX
Module APS Configuration Procedure, for details.
1. When activated with the Test/Enable switch on the Offline unit, it forces a
switch to protection. (Offline MUX becomes Online MUX).
2. When activated with the Test/Enable switch from the ONLINE unit, it
toggles the APS Lockout Status.
1.5 Install the HTU-C
The Total Access 3000 HTU-C delivers a T1 signal over an HDSL local loop. The
local loop in the HLSS configuration includes two independent 4-wire circuits. The
two HTU-Cs communicate to their respective remote units, the HTU-Rs. When an
HLSS switch occurs, the AUX circuit takes over transmitting the data load from the
MAIN circuit until the MAIN circuit is restored.
1. Install The HTU-Cs into Total Access 3000
Electronic modules can be damaged by static electrical discharge. Before
handling modules, wear an anti-static discharge wrist strap to prevent damage to
electronic components. Place modules in anti-static packing material when
transporting or storing. When working on modules, always place them on an
approved anti-static mat that is electrically grounded.
1.) Gently but firmly push the HTU-C into the appropriate odd-numbered
slot (which will be the MAIN HDSL circuit). Compatible slots can be
any slot pair that starts with an odd number (MAIN) and includes the
adjacent (to the right) even-numbered slot (AUX). Compatible slot pairs
are further designated by the bracket notation around the slot pairs on
the silk screen just below the physical slots on the front of the Total
Access 3000. Simultaneous thumb pressure at the top (above the PWR
LED) and bottom (below the ACT LED) of the unit will ensure a good
seat of the HTU-C pins into the backplane connector. Repeat this step
for the AUX HTU-C to be installed in the adjacent (even, to the right)
slot.
