Converting RT Channel Bank Feature Package
Introduction
This Tab provides procedures to convert a remote terminal (RT) system (blue or
white) from one feature package to another. Procedures for adding or removing

Feature Packages

choice of supporting common units [transmit/receive unit (TRU), line interface unit
(LIU), channel test unit (CTU), digital test unit (DTU), line switch unit (LSU), and
