SCP-PCU796-010-04H Theory of Operation RODUCT VERVIEW This practice describes the PCU-796 List 1, a pair gain test controller (PGTC) Conditioner Unit (PCU), that provides control signals from the PGTC to I-MLT-2 during Mechanized Loop Testing (Integrated MLT) (see Figure 1). HEORY OF PERATION To complete MLT testing on a PG-Plus... - Page 12 Theory of Operation SCP-PCU796-010-04H The PCU-796 is not required in Central Offices (CO) that use Nonintegrated MLT-2 systems. Figure 2 shows the typical connections of Nonintegrated MLT-2. In this case, the Sleeve lead passes through the PGTC to the No Test Trunk in the switch.

SCP-PCU796-010-04H Description and Features The differences in the Integrated MLT-2 case are shown in Figure 3. Here the PCU-796 is necessary because a No Test Trunk is not present in this set-up. The PCU-796 monitors the unconnected Sleeve lead and responds with -48 V battery coupled through a resistor to the Trunk Ring lead when the MLT opens its Sleeve lead at the end of testing. -
