Augments the dsx1SendCode object from the DS1 MIB of RFC 1406. This object defines other codes that are not defined by dsx1SendCode. The value of other(1) can never be set by management operation. This object and the dsx1SendCode object interoperate. When the value of dsx1SendCode is set to something other than dsx1SendOtherTestPattern(8), then the value of this object is set to other(1). When the value of this object is set to something other than other(1), the the value of dsx1SendCode is set to dsx1SendOtherTestPattern(8). This object and the gdcDsx1ProgPattern object interrelate. When this object is set to the value sendProgPattern(4), the value of the gdcDsx1ProgPattern object is used as the 16 bit user programmable pattern. The values send511PatternWithLT(11), send511PatternWithRT(12), send2047PatternWithLT(13), send2047PatternWithRT(14), sendQRSPatternWithLT(15), sendQRSPatternWithRT(16), sendProgPatternWithLT(17), sendProgPatternWithRT(18), send3in24PatternWithRT(19) indicate that the given pattern test is running in conjunction with a local test (LT) or remote test (RT). gdcDsx1LoopbackConfig is updated to indicate this as well. When one of these tests are running, and dsx1SendCode is set to dsx1SendNoCode(1), both the pattern and the loopback are terminated. However, if dsx1LoopbackConfig is set to dsx1NoLoop(1), and a pattern with LT is in progres, only the loopback portion is terminated.
