POWER	● OFF	No power is present on the unit
	● YELLOW	Unit is Out-of-Service
	● GREEN	Unit is In-Service
STATUS	● OFF	Unit is Out-of-Service, Unassigned
	● GREEN	DS3 signal is present and synchronized
	● RED	Local alarm or local and remote alarm condition detected
	● YELLOW	Remote alarm condition detected
TEST	● OFF	Unit is not in loopback
	● YELLOW	Loopback active
LOCKOUT	● OFF	APS enabled
	● YELLOW	APS disabled due to INHIBIT
	● RED	APS is locked out due to three non-forced APS events within a
		24-hour period
ONLINE	● OFF	Unit is stand-by unit (unit receives from network but does not
		transmit to network)
	● GREEN	Unit is on-line unit (unit receives from and transmits to network)

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
Line Build Out	Short, Long	Short
Clock Source	Local, Loop	Loop
Service State	In Service, OOS-Unassigned, OOS-Maint	OOS-Unassigned
Linked Provisioning	Enabled, Disabled	Enabled
Line Code	B3ZS (cannot be changed)	B3ZS

■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.

Service	Report	Report	Switch to	Allow	Trib	Ntwrk	Allow	Allow	Allow
State	Alarms	TL1 PM	Provide	Forced	Data	Data	Dwnld	Prov	Maint
		Data	Service	Switch
			on Fault	into Unit
OOS, Un	N	Y	N	N	AIS	IDLE	Y	Y	Y
OOS, Ma	N	Y	Y	Y	Norm	Norm	Y	Y	Y
In Service	Y	Y	Y	Y	Norm	Norm	N	N	N

■Linked Provisioning - when enabled, automatically transfers provisioning changes made to the enabled unit to the other unit.

■Line Code - this value is hardcoded to B3ZS and cannot be changed.
