Description
The SET command selects the bearer service <name> with data rate <speed>, and
the connection element <ce> to be used when data calls are originated (refer 3GPP
TS 22.002). Values may also be used during mobile terminated data call setup,
especially in case of single numbering scheme calls (refer +CSNS).
The TEST command returns values supported as compound values.
