Соединение PPPD в Linux разорвано -> LCP прерван узлом (запрос пользователя)

Я пытаюсь установить соединение GPRS PPP (с сетью передачи данных Rogers Wireless в Канаде) с помощью модема Telit HE910, но кажется, что что-то идет не так во время согласования DNS:

Serial connection established. using channel 16 Using interface ppp0 Connect: ppp0 <--> /dev/ttyACM3 rcvd [LCP ConfReq id=0x1 <asyncmap 0x0> <auth pap> <magic 0x218a9f69> <pcomp> <accomp>] sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0x10535642>] sent [LCP ConfRej id=0x1 <pcomp> <accomp>] rcvd [LCP ConfAck id=0x1 <asyncmap 0x0> <magic 0x10535642>] rcvd [LCP ConfReq id=0x2 <asyncmap 0x0> <auth pap> <magic 0x218a9f69>] sent [LCP ConfAck id=0x2 <asyncmap 0x0> <auth pap> <magic 0x218a9f69>] sent [LCP EchoReq id=0x0 magic=0x10535642] sent [PAP AuthReq id=0x1 user="cm-debian" password=""] rcvd [LCP EchoRep id=0x0 magic=0x218a9f69] rcvd [PAP AuthAck id=0x1 ""] PAP authentication succeeded kernel does not support PPP filtering sent [IPCP ConfReq id=0x1 <addr 0.0.0.0> <ms-dns1 0.0.0.0> <ms-dns2 0.0.0.0>] rcvd [IPCP ConfNak id=0x1 <ms-dns1 10.11.12.13> <ms-dns2 10.11.12.14>] sent [IPCP ConfReq id=0x2 <addr 0.0.0.0> <ms-dns1 10.11.12.13> <ms-dns2 10.11.12.14>] rcvd [IPCP ConfNak id=0x2 <ms-dns1 10.11.12.13> <ms-dns2 10.11.12.14>] sent [IPCP ConfReq id=0x3 <addr 0.0.0.0> <ms-dns1 10.11.12.13> <ms-dns2 10.11.12.14>] rcvd [LCP TermReq id=0x3 "User request"] LCP terminated by peer (User request) sent [LCP TermAck id=0x3] rcvd [IPCP ConfNak id=0x3 <ms-dns1 10.11.12.13> <ms-dns2 10.11.12.14>] Discarded non-LCP packet when LCP not open Connection terminated. Modem hangup 

Вот действующие параметры PPP:

И вот мой чат-файл:

Может ли кто-нибудь помочь мне понять, почему коллега отправил мне LCP TermReq?
