4.2.7
JVM Interfaces
Figure 8:  Interface Configuration
Java ME, CLDC and MIDP were implemented by SUN. IMP-NG is a stripped down version of 
MIDP 2.0 and does not include the graphical interface LCDUI. There are also additional APIs 
like the File I/O and the AT command API. Documentation for Java ME and CLDC can be found 
at 
. Documentation for the other APIs is found in 
4.2.7.1
IP Networking
IMP-NG provides access to TCP/IP similarly to MIDP 2.0.
Because the used network connection, CSD or GPRS, is fully transparent to the Java interface, 
the CSD and GPRS parameters must be defined separately either by the AT command 
AT^SJNET 
 or by parameters given to the connector open method, see 
.
4.2.7.2
Media
The playTone method and the tone sequence player are supported. For optimum performance 
use notes in the range of 48 to 105. Tones outside this range are affected by audio hardware 
filtering (see 
).
4.2.7.3
Other Interfaces
Neither the PushRegistry interfaces and mechanisms nor any URL schemes for the Platform-
Request method are supported. See
