кто-нибудь в PPP/LCP шарит?

такая трабла, pppd не выдаёт адреса. на мой запрос выдаёт 0.0.0.0, потом рубит. 
модем teltonika pci g10 (он же PM1000). 
на билайновскую симку врубает с первого раза. 
эта симка в сименсе тоже работает на ура.

вот здесь идёт запрос адреса, в ответ -- нули. отключать компрессию пробовал.
