4.2. Features in Release Version 1.6.xx
Numerous changes have occurred in release 1.6.xx. Most of these relate to IP
and 3G IP connections. As a result, these sections have been extracted from all
codec reference manuals and have been amalgamated into a manual titled the
“IP & 3GIP Streaming Reference Manual”.
This manual contains all the latest connection information relating to IP and
3GIP in general. It also contains information about SIP connectivity and updated
quick start guides for studio and field unit codecs, as well as for wireless 3G
networks.
Following is a summary of the new and updated features that are contained in
the “IP & 3GIP Streaming Reference Manual”.
Updates to how to connect a codec for IP in a studio using a static IP
address;
Updates to how to connect a codec for IP in the field using DHCP
addresses;
Updates to how to connect a codec over 3GIP using new codec menus;
3G Modules available for GSM, GSM Voice, UMTS, EVDO and HSDPA
connections;
Codec interoperability using SIP;
