VoIP Networks with PSTN — Example 17
Mixed Digital and Analog Voice Daughtercards
This dialing scheme illustrates how to connect a digital voice switching daughtercard (VSD) to
an analog voice switching daughtercard (VSA) to send and receive calls. It also depicts a
remote PSTN connection as part of a VoIP network in which a VSA providing analog connec-
tions using Plain Old Telephone Service (POTS) is connected to the PSTN via a remote VSD.

PBX #2 can send four simultaneous PSTN calls (on FXS LS lines) to the VoIP network;
however, it can only receive two simultaneous calls (on FXO LS lines) from the VoIP
network.

On Voice Daughtercard #2, the Foreign Exchange Station (FXS) Loop Start lines are used to
send calls to the VoIP network from the PBX via analog trunks, whereas the Foreign
Exchange Office (FXO) Loop Start lines are used to receive calls from the VoIP network and
send them to the PBX.
