If thevalue is null or omitted, then the subscription value will be requested.An optional special code placed at the beginning of indicatesthe kind of the authentification handling MS/network and may be:- CHAP: challenge handshake authentification protocol- PAP: personal authentification protocol- NONE: authentification protocol not used- code omitted: authentification protocol not usedAn exemple for the usage of is: +CGDCONT=1,"IP","CHAP:internet.t-d1.de",0,0PDP context identifier meaning a numeric parameter, which specifies aparticular PDP context definition. This parameter is valid only locally onthe interface TE-MT.is a numeric parameter that controls PDP data compression and canhave the values:- 0: off- 1: on (manufacturer preferred compression)- 2 : V.42bis data compressionis a numeric parameter which specifies the delay class:erroneous shall be delivered or not.
