> 4.2.8 | JVM Interfaces

> Figure 6: Interface Configuration
> Java ME, CLDC and MIDP were implemented by SUN. IMP-NG is a stripped down version of MIDP 2.0 prepared by Siemens and does not include the graphical interface LCDUI. Siemens developed additional APIs like the File I/O and the AT command API. Documentation for Java ME and CLDC can be found at http://java.sun.com/javame/. Documentation for the other APIs is found in [3].

> 4.2.8.1 | 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 [1] or by parameters given to the connector open method, see [3].

> 4.2.8.2 | 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 [2]).
> Media package is only supported in TC65. See [3].

> 4.2.8.3 | Other Interfaces

> Neither the PushRegistry interfaces and mechanisms nor any URL schemes for the PlatformRequest method are supported. See [3].
