VoIP Networks with Interoperability — Example 26
Mixed European Digital and Analog Voice Daughtercards
This dialing scheme is used for European countries using E1 ISDN PRI (ETSI) with analog and
digital VoIP gateways together on the same VoIP network. A-Law companding on the VSA is
generally used in Europe (instead of the North American Mu-Law companding).
On the VSA, the Foreign Exchange Station (FXS) Loop Start lines are used to send calls to the
VoIP network from the telephones via analog trunks; all digits are automatically stripped on
incoming FXS calls.
Installation of an analog voice switching daughtercard (VSA with FXS module) is also required
in addition to the standard VSD. See Chapter 2, “VoIP Daughtercards” for a description of the
various daughtercards, and Chapter 4, “Setup and Installation” for details on installation.
