Using the DS1 CPE Loopback Jack (apparatus code 700A, comcode 
107988867), a technician can test the DS1 span between the system and the 
network interface point. The loopback jack is required when DC power appears 
at the interface to the ICSU. 
The loopback jack isolates...

9. Repeat Steps 5 through 8 as desired to observe bit error rate 
characteristics. Also, wait 1 to 10 minutes between Steps 5 through 7. One 
minute without errors translates to better than a 1 in 10 to the eighth error 
rate. Ten minutes without errors translates to better than a 1 in 10 to the 
ninth...
