INSTALLATION PROCEDURE
I 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.
I 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
I
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.
I 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.

DS3 MUX
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
I
sensitive) and can be changed upon initial login.
I Select Common A or Common B from the Total Access Menu.
Select option 2, Provisioning, and press <enter>.

I Framing - sets the DS3 framing.
I 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.
I 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.
