Sim senhor, inclusive tive que modificar o /etc/ppp/pap-secrets, porém
quando utilizo o +pap o provedor recusa "peer refused to authenticate:
terminating link":

Então o lógico e natural seria assumir que a autenticação não é PAP, porém
outro modem conecta sem problemas:


Connect: ppp0 <--> /dev/ttyUSB3
sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xa053d16f> <pcomp> <accomp>]

Infelizmente ainda não consegui um contato direto com a operadora.

Muito obrigado pela ajuda Bruno, se houver outra dica ficarei extramemente
agradecido.

Obrigado.
