through every administered DS1 facil ity channel. Two different test patterns are
used, these are hexadecimal valu es 55 and AA.
On a Standard Reliability and Hig h Reliability System (no PNC duplication), th is
test can only be executed at the end-point whic h is closer to the SPE relative to
the neighbor DS1 CONV circuit pac k because of its impac ts on the system
control links, also the comp letion of the test will be delayed in this configuration to
wait for the recovery of the system control links. O n a Critical Reliability System
(PNC Duplication), test can b e executed at any DS1 CONV circuit p ack.
