Chapter 1. Introduction

Pattern Generation

The TSU ACE offers five available test patterns: QRSS, 511, 1:8, All
Ones, and All Zeros.

QRSS

The TSU ACE has an internal QRSS pattern generator and detector.
The pattern only appears in the DS0s assigned to the Nx56K/64K port.
The QRSS test pattern can be used in conjunction with network loop-
backs to perform end-to-end tests.
511
The TSU ACE has an internal 511 pattern generator and detector. The
pattern only appears in the DS0s assigned to the Nx56K/64K port.
The 511 test pattern can be used in conjunction with network loop-
backs to perform end-to-end tests.
1:8
The 1:8 is a stress pattern which places the maximum number of 0s in
the transmitted data. This is always done over all DS0s. This pattern
is used in conjunction with external test equipment to determine if the
T1 line is performing acceptably under a stress condition. Each chan-
nel of the T1 has only one bit set.

All Zeros

Generates an all zeros pattern in every channel.

All Ones

Generates an all ones pattern in every channel.
