8.3.2 Configuration Implementation
In this example, the subscriber interface board provides the access of 24 VDSL users,
32 ADSL users, and four Ethernet users. The embedded BAS provides the functions of
user authentication & authorization. The embedded BAS implements uplink. Therefore,
this example provides one SCBF, one VDSL subscriber interface board, one ADSL
subscriber interface board, corresponding ADSL/VDSL splitter board, one LTC, one
Layer 2 Ethernet uplink subboard, one embedded BAS, one backplane, 24 VDSL
subscriber premises devices, 32 ADSL subscriber premises, and other devices.
Hardware configuration is shown in Table B.1-1.
