Figure 18-10. Send DS1 Payload Pattern
Security: Level 2 (operator)
Syntax: send ds1 <n> payload
<allones|allzeros|f1in8|p2e11|p2e15|p2e23|qrss>
Field Description
n DS1 number, 1 to 32, or a range of numbers such as 2-8.
allones Send framed all-ones pattern. This can be used as a “keep alive”
signal, idle code, and in measuring the T1 power level.
allzeros Send framed all-zeros pattern. This can be used to test T1 circuits
for B8ZS clear channel capability and to find equipment
incorrectly set to AMI line code.
Note: When using an all-zeros pattern, a T1 test set (such as a
T-Berd 224 or Sunset T3) must be used to monitor for errors in
the all-zeros pattern from the Access Navigator or looped back
from a far-end network element.
f1in8 Send framed 1-in-8 pattern (also called a 1-and-7 pattern) in
which each payload byte contains the bit pattern 01000000.
(Minimal ones density test for T1 circuits with AMI coding.)
p2e11 Send 2
11
–1 pattern with a maximum of 10 consecutive zeros and
11 consecutive ones. (Minimum stress testing.)
p2e15 Send 2
15
–1 pattern with a maximum of 14 consecutive zeros and
15 consecutive ones. (Provides maximum number of consecutive
zeros permissible in framed, non-B8ZS testing.)
p2e23 Send 2
23
–1 pattern with a maximum of 22 consecutive zeros and
23 consecutive ones. (Maximum stress testing.)
