T1 ESF CSU ACE User Manual

 

 

Pattern Generation

The T1 ESF CSU ACE offers three test patterns: All Ones, All Zeros, and 1:8. These patterns can be initiated from the front panel, through the EIA-232 control port, or remotely via a management software like T-Watch.

All Ones

The All Ones pattern sends ones in all the payload bits.

All Zeroes

The All Zeros pattern sends zeros in all the payload bits and is useful for testing line code configuration (AMI/B8ZS mismatches).

1 in 8 (1:8)

Each channel of the T1 has only one bit set. This pattern is used in conjunction with external test equipment to determine whether the T1 line is performing acceptably under a stress condition.

APPLICATIONS

Three applications are shown in this section. Figure 1-7 on page 27 shows a general data application; Figure 1-8 on page 28 shows a general voice application; and Figure 1-9 on page 28 shows a channel bank application.
