Enumeration
Test pattern used for locally initiated remote loopback.
Valid only if a remote loopback was last performed.
Following patterns valid for T1 or Switched 56k CSU/DSU:
noPattern - no specific pattern is used, data provided by
the DTE. Used to loopback transmit data.
Following patterns only valid for T1 CSU/DSU:
patternQRW - Quasi-Random Word pattern. Specifically used to
measure Bit Error Rates.
pattern0In1 - repeated binary pattern of '0' or all zeros.
Typically used for verification of B8ZS optioning
of the T1 facility.
pattern1In1 - repeated binary pattern of '1' or all ones.
Typically used for signal power measurements.
pattern1In2 - repeated binary pattern of '01'. Typically
used in testing for bridge taps.
pattern1In3 - repeated binary pattern of '001'. Typically
used to terminate a remote loopback.
pattern1In5 - repeated binary pattern of '00001'. Typically
used to put the remote unit in loopback.
pattern1In8 - repeated binary pattern of '00000001'.
Typically used to stress the timing recovery circuits
of repeaters and other intermediate equipment.
pattern3In24 - repeated binary pattern of
'000000000000000000000111' or hex '000007'.
Typically used to test for one's density
(consecutive zeros) tolerance on AMI lines.
patternUser - user defined pattern.
Following patterns only valid for Switched 56k CSU/DSU:
pattern2047 - 2047 bit long pseudorandom pattern containing a
maximum of 10 sequential zeros and 11 sequential ones.
pattern511 - 511 bit long pseudorandom pattern containing a
maximum of 8 sequential zeros and 9 sequential ones.
patternStressDDS1 - DDS Stress test pattern #1.
patternStressDDS2 - DDS Stress test pattern #2.
patternStressDDS3 - DDS Stress test pattern #3.
patternStressDDS4 - DDS Stress test pattern #4.
