4.7. Connecting the Subscriber Cables
The rear leading-out mode is adopted for the ADSL/VDSL subscriber cables of 3P@C 4450E. The special-
purpose 3*8 cable connectors are used to connect with the DIN connectors on the rear panel. The subscriber
cables are divided into two types: LU connection subscriber cables and LC connection telephone switch cables.
The connector of the LU subscriber cable has 3 marks: UP X1, UP X2 and UP X3, which are connected on the
DIN connector on the backplane from the top down in the sequence of UP X1, UP X2 and UP X3. The connector
of the LC telephone switch cable has 3 marks: DOWN X1, DOWN X2 and DOWN X3, which are connected to
the DIN connectors in the lower row on the backplane from the top down in the sequence of DOWN X3, DOWN
X2 and DOWN X1. LU and LC subscriber cables are installed on the DIN connectors on the backplane (as
shown in Figure 4-45). The pinouts of the LU subscriber cable are shown in Figure 4-46 and Table 4-3, while the
pinouts of the LC telephone switch cable are shown in Figure 4-47 and Table 4-4.
