The converter voltage and ring test portions of LCM_REX_TEST require

wait states and different test resources. These states and resources cause

delays in SREX main task performance that are not acceptable.

LCMCOV_REX_TEST, running at a lower priority, starts these tests

separate from the LCM_REX_TEST. LCMCOV_REX_TEST requires

logical test unit (LTU) connections in the maintenance line card. An LCM

unit can access the single LTU when the other unit is OOS. This resource

limit precludes concurrent LCMCOV_REX_TEST performance. The entry

of the PARALLEL performance field for LCMCOV_REX_TEST, in Table

REXSCHED, allows a maximum of one.
