These patterns can beinitiated from the front panel, through the EIA-232 control port, or remotely via a management softwarelike T-Watch.All OnesThe All Ones pattern sends ones in all the payload bits.All ZeroesThe 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 testequipment to determine whether the T1 line is performing acceptably under a stress condition.APPLICATIONSThree applications are shown in this section.
