This table monitors and controls the T1-617 Annex-D
parameters used by the channel units. There is one
table row for every channel unit in every bank. The
table is indexed first using the Cisco 90 Series channel
bank digroup number, then the channel unit number (1 to 24).
For best performance, all of the channel units in a
given bank should be set to identical values. These
values are typically set using global parameters in the
frxDefaultTable instead of directly via this table.
