Mike,


I'm afraid I didn't make myself clear.  I KNOW there are a lot of 

threshold registers.  I'm trying to figure out how many DEFAULT

threshold registers there needs to be.  My question was in the

context to the particular sentance I quoted.


So, let me ask it another way.  If I have a box with a DS1 port, a DS2

port, an OC3 port and two (2) OC12 ports, I'll have five (5) separate 

threshold registers for the current SES errors (one for each port).

How many default threshold registers do I need for SES 15 minute interval

errors to satisfy ANS1 T1.231-1997 claues 9.1.5.2, paragragh 2?


a) two (one for DS1/DS2 and one of SONET)

b) four (one for DS1, one for DS2, one for OC3 and one for OC12)

c) some other set.
