It is assumed that the user is familiar with the concepts outlined in [3GPP_TS27], and has a working
knowledge of the Hayes AT command set.
There is a one-to-one mapping between each PPPoE connection and each primary PDP context activated by
the SATCOM system. A maximum of 11 PDP contexts is supported, comprising of both primary and secondary
contexts.
9.2.2 Connection Authentication
User Authentication may be required for some connections. In such cases, a user name and password may be
supplied in the PPPoE connection instance. Before attempting such connections, the user should verify with
their Communication Service Provider (CSP) whether authentication is required for a particular service or type
of IP address.
The AVIATOR S system supports the exchange of a username and password during the PPPoE/PPP negotiation
(IPCP Phase) using PAP/CHAP authentication.
9.2.3 PPPoE Service Name
A PPPoE service name may be used to customize the connection type, properties and quality-of-service (QoS)
by specifying a series of AT strings or parameters in the Service Name field of by the PPPoE client connection
properties (the connecting device).
When the service name is left blank/empty, User ORT configured defaults are used in order to create the PDP
context with known properties.
Refer to Table 9-1 for the list of supported service name options.
As an alternative to a predefined service name option, the PPPoE client may define the full AT string. The
letters “AT” must be present and the command string needs to specify both the CGEQREQ and CGEQMIN to
ensure the desired QoS is provided. See [A781] section 3.3.11.3.1.
Example:
SBB:AT+CGDCONT=1,“bgan.inmarsat.com”;+CGEQREQ=1,1,64,64,64,64;+CGEQMIN=1,1,64,64,64,64
