1.1.1.7 Structure of the ADUB

The ADUB is used to provide ADSL data access services. Each ADUB provides 32 ADSL subscriber

interfaces. The subscriber interface is connected to the DIN connector on the backplane, thus

implementing data transmission via the existing data switching line (such as telephone line) and

separation of data transmission from voice transmission.

The ADUB features high security and supports IEEE 802.1Q VLAN to provide secure isolation for

each subscriber. In addition, it supports the port locking function to prevent illegal subscribers from

accessing the network.

ADUB adopts the -48 V DC power supply with an allowable voltage ranging from -44 V DC to -60 V

DC. It supports hot plugging, and can identify the rack slots, thus facilitating the management and

maintenance.

When used in 3P@C 4450E, the ADUBs can be inserted in slots 2 ~ 15 of the 10U chassis, as shown

in Figure 2-15:
