SASS Test Number Access

SASS Test Number Access
by Lineside

	SASS test numbers can be interesting to find and play with. If you've 
ever heard of DATU's (Direct Access Test Unit) or have played with one, you'd
find that SASS numbers are very similar to them. (If you want to know more 
about DATU's, read MMX's article in this issue.)

	For comparison, here are the test functions of a DATU:

-Audio Monitor (busy, idle line, intercept)
-Short ring to ground (tip open)
-Ring Ground
-Short tip to ground (ring open)
-High level tone on tip and ring
-High level tone on ring (tip grounded)
-High level tone on tip (ring grounded)
-Low level tone
-Open line
-Short line
-Permanent signal release
(taken from NPA DATU text)

	When calling a SASS number, instead of having to directly enter a security 
code it will first of all respond with an ANAC (meaning it gives you the number you 
are calling from.) It will do so twice. The time during the second ANAC is when you 
enter your 4-digit security code (BellSouth seems to love using 1111 and 1122 for a 
lot of their stuff, including their SASS and DATU). After doing so, you get to the menu. 
	The menu consists of the following functions and tests which you 
select using different DTMF keys:

	4- Busy line verification (for deluxe call waiting/ memory call)
	5- A DTMF keypad test
	6- Number identification
	7- Ringback test
	8- Transmission measurement tests:

			1- Single tone: choose between 03(304Hz) and 
                           32 (3204Hz)
			3- Three tone slope (400Hz,1004Hz, 2804Hz)
			5- Quiet termination
			6- Milliwatt tone
			7- Tone sweep: choose start and end tone between
                           03(304Hz) to 32 (3204Hz). For a full tone 
                           sweep you enter *
			8- Number identification sweep: 1200HZ- 2200HZ 
                           (for caller id)
			9- Data sweep (900Hz- 2800Hz)
			0- 10 tone slope (304Hz- 3204Hz)
			*- return to main menu

Instead of forcing a disconnect with ## as you would with a DATU, after using the 
SASS you can just hangup. 

	SASS functions such as the ANAC, ringback and DTMF test (for finding out 
those stored #'s in butt-sets???) can be pretty useful. As for finding SASS numbers 
in your area, the telco may or may not have a designated or often used prefix.

	In my area the DATU and SASS numbers seem to be pretty mixed up and spread out 
while regular test numbers such as ANAC usually share their prefix with lots of other
interesting telco numbers. Again, this could be different in your area.

If you have any questions, especially if you are in the south-east area, 
please contact me with any questions or comments.
