Medium Access Control (MAC) and Physical Layer (PHY) - CISE

• TD Repeaters
The Radius server checks:
• The MAC address of the slave applying for authentication
• The MAC address of the master placing the request
The Radius server replies:
• Accept / Reject
• Profile number
The profile number relates to the QoS and VLAN settings for the given slave (Radius user).
If Access Protocol authentication is disabled, all slaves get access to the network with the default settings (profile
1).
A third type of authentication is possible: Authlist. In this mode, the autoconfiguration file of the master contains all
the slaves that are allowed to connect and their associated profile.
12.2.4 Auto-configuration at Modem Boot
autoconfiguration parameters on booting. When any node boots, there may be a parameter stored in the non-volatile
memory called GENERAL_USE_AUTOCONF. When this value is YES, the node boots in auto-configuration
mode. When this value is NO, the node boots from local settings.
Inside the autoconfiguration boot mode there are two possibilities depending on whether or not PTTP is performed.
12.2.4.1 Autoconfiguration PTTP Boot
send PTTP requests. When this protocol ends, the modem has the minimum information to successfully connect to
the backbone and execute DHCP and TFTP.
The node then performs a DHCP request to get an IP configuration, the phone number (if required) and the name of
the auto-configuration file, as well as the TFTP server where the file is located. Then it downloads the file and
configures the node accordingly.
12.2.4.2 Autoconfiguration no PTTP Boot
In this autoconfiguration boot modality, the modem has been already configured somehow (see section 12.2.5 for
more information) to successfully execute DHCP and TFTP so it skips PTTP.
