2.3.3.ADSL Unit Board (ADUB)
1.1.1.7Structure 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
When used in 3P@C 4450E, the ADUBs can be inserted in slots 2 ~ 15 of the 10U chassis, as shown in Figure
