APS PUSHBUTTON
When depressed simultaneously with the Test/Enable switch on the Off-line unit, a
protection switch is forced.
When depressed with the Test/Enable switch on the On-line unit, it toggles APS status.
TEST/ENABLE BUTTON
When depressed alone, tests all unit LEDs (multicolor LEDs appear YELLOW).
When depressed simultaneously with the APS switch on the Off-line unit, a protection switch
is forced.
INSTALLATION PROCEDURE
Ensure the TA 3000 system chassis is properly mounted and wired for power. BNC Adapter
Module, P/N 1181004L1, is required for DS3 operation. The adapter is mounted to connector
J34 (J20 on 19” shelf ), located in the lower right corner of the backplane.
Ensure SCU is seated and receiving power.
Plug DS3 module into slot A or B of system chassis. Gently but firmly push the DS3 Mux into
one of the Mux slots, A or B, 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.
Allow the self-test LED sequence to complete. The self- test should take about 40 seconds.
Upon completion, the POWER LED will be YELLOW, indicating the unit is Out-of-Service
and the STATUS LED will be OFF indicating the unit is in the Unassigned (OOS-UA) state.
PROVISIONING THE DS3 MULTIPLEXER
To provision the DS3 Mux, connect a terminal emulator via the RS-232 (DB-9) connector on the faceplate
of the SCU. The terminal must be VT-100 or compatible and set for 9600 bps, 8 data bits, no parity and 1
stop bit.
At the LOGON screen, enter the system password. Note the default password is “PASSWORD” (case
sensitive) and can be changed upon initial login.
Select Common A or Common B from the Total Access Menu.
Select option 2, Provisioning, and press <enter>.
The following table lists the provisioning settings and their default values.
Options Settings Default
Framing M13, C-Bit, Auto detect Auto detect

Framing - sets the DS3 framing.
Line Build Out - set LBO to either Short or Long.
Short - cable length is less than 225 feet of 734A or equivalent coaxial cable or less than
100 feet of Lucent 735 or equivalent coaxial cable.
Long - cable length is greater than 225 feet of 734A or equivalent coaxial cable or
greater than 100 feet of Lucent 735 or equivalent coaxial cable.
Clock Source - selects where the transmit clock derives its timing.
Local - derives its clock from an on-board oscillator.
Loop - derives its clock from the incoming DS3 data stream.
Service States - the following table lists the operations allowed in each state.
