GENERAL INFORMATION 
SASS is a transmission conditioning unit, a printed wiring card that employs 
a microprocessor control of test functions and provides voice prompting.  The
card is installed in an MFT bay and connected to the switch through an 
outgoing trunk.  A dedicated POTS line is required for the ringback feature.
This Single Serving Access System will allow both outside field technicians 
as well as LFO technicians the ability to perform multiple test functions 
using one access number.  

The Unit Test Features are:
	
- ANI
- Single Tone Generation
- Three Tone slope
- Ten Tone Slope
- Full Tone Sweep
- Caller ID Transmission
- Data Sweep
- Quiet Termination
- Keypad Test
	
CENTRAL OFFICE (CO) 
REQUIREMENTS    
1. An MFT slot
2. An outgoing trunk OR A D4 port equipped with a DPT Channel Unit.
3. A new Trunk Group assignment will be established
4. The SASS Access Number wil need to be route indexed to the trunk or port 
   assigned.
5. Assignment and cross connect to a POTS line for ringback capabilities. 

CENTRAL OFFICE (CO) 
PROCESS (1) Wiring the Circuit
1. You will receive two service orders for your SASS circuit. One for the 
design itself (se word) and one for the POTS line (1ML) associated with it.  
The POTS order will consist of only an OE assignment used for ringback 
capabilities. 

NOTE 1)  The design portion of your order will resemble a DID circuit.
NOTE 2)  Every effort will be made to use a digital trunk assignment, 
	    however, if none are available, an analog trunk will be used in its 
	    place.  
NOTE 3)  Make sure the channel unit used in the circuit is a D4CD200 
	    (terminating).

CENTRAL OFFICE (CO) 
PROCESS (2) Installing and Optioning The Channel Unit 
Install the SASS Unit into the designated MFT slot.  Once the plug-in has 
been installed it should be optioned according to the manufacturers 
instructions on the card.  
	
CENTRAL OFFICE (CO) 
PROCESS (3) Initial Power-Up Verification 
Once the SASS unit is installed and optioned the Initial Power-up 
verification must be performed at the unit itself.  

CENTRAL OFFICE (CO)
PROCESS (4) Procedure for Setting Transmission Levels 
Once the SASS unit has passed the Initial Power-up verification the 
Transmission Levels must be set for the unit.  The following is the procedure 
for setting transmission levels on a newly installed SASS Unit.  This 
function must be performed at the mainframe to any pair assigned to an OE in 
the respective switch in which the SASS unit was installed.  The pair must be 
open and the reading taken toward the line card.   
	
STEP ACTION    
1 At the mainframe, remove the coils from any working pair assigned to an OE
  in the respective switch.     
2 Draw dial tone on the OE side of the open and dial the SASS access number. 
3 Enter the SASS Security Code after the number announcement.  The default
  Security Code is 222-2222.
4 Press 3 to Read or Change Prefixes
5 Press 5 to Generate Test Tone.
6 Enter * to Generate System Tone
7 Measure Tone with a transmission measurement test set.  Should measure a
  level of 0dbBRNC.   
NOTE 1)  Adjustments may be made by; entering a 6 to increase level by 0.1 dB 
each time the 6 is depressed, or entering 7 to decrease the level by 0.1 dB 
each time the 7 is depressed.   
8 When you have completed setting the db levels, hangup to terminate the 
  call. 
9 A test must be performed on least three (3) prefixes to determine whether 
  the db levels were set correctly in all prefixes..  A deviation of + or 
  -1/2 db is acceptable.  If tests reveal any variance greater than + or -1/2 
  db, you must repeat the procedure for Setting Tranmission Levels for every 
  prefix.

PROCESS (5) Testing The Newly Installed SASS Unit 
When the SASS installation is complete, call the Test System Health Group to 
test the newly installed unit.  They will in turn close the order out with 
OCS.

PROCESS (6) Troubleshooting A Newly Installed SASS Unit 
When the SASS installation is complete, the Initial Power-up verification has 
been performed, the transmission levels have been set and your circuit is 
still not turned up, try the following troubleshooting procedures.

Questions?
At what point will I know that translations are typed in.  
At what point does the ntec ask the ess to idle trunk? Before setting levels.
