the Expanded (G.729 only) mode there are more voice channels available per
node than in hybrid mode. However the quality of the audio data is somewhat
poorer as a result of the compression. The configured mode is always valid for
the entire node.
• GSM
Enhanced functionality is achieved for integrated GSM terminals by providing
special DTMF receivers during the call connection. Suffix dialling procedures
such as enquiry calls or setting up a conference can be carried out as a result.
The number of GSM channels – and therefore the number of DTMF receivers –
depends on the number of users with integrated GSM terminals who want to
use this functionality simultaneously. One
GSM Terminals licence is required for
each integrated GSM terminal.
The allocatable functions are determined using AIMS under CM_1_1_7. The DSP
cards provide additional functions as indicated in the following table. All the possi-
ble combinations are listed, with the maximum number of voice channels.

G.711 or to VoIP . The setting is valid for all the DSP chips of a node. For
VoIP mode = Only VoIP G.711 the following applies:
