The DIN connectors are used for the subscriber line interfaces in two rows (upper and lower). Each DSL service board needs 2 groups of subscriber lines. One group is the LU line that corresponds to the connector in the upper row and is connected to the subscriber line, and the other group is the LC line that corresponds to the connector in the lower row and is connected to the PSTN switch. The slots correspond to the types of the service boards inserted in the chassis front to support subscribers of different quantities. For the definition and connection method of subscriber lines, refer to the contents in Section 4.7.
For ADUB/ADUC, each slot supports 32 subscribers.
For VDUB, each slot supports 24 subscribers.
