DTE Interface Loopbacks

Loops all data from the terminal interface (T1) back towards the T1.
This loopback may be initiated using front panel, EIA-232 control
port, or T-Watch commands. The DTE (or external test equipment)
must provide any test pattern in order to check the DTE interface.
See Figure 1-5.

Figure 1-5. DTE Interface Loopback

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.
