2.3.3 Analog Card – 4 Port (FXS)
Four analog ports are contained on a separate low-profile PCI-Express Card connected to the main gateway
board using a flat ribbon cable.

The cable transports audio signals through a TDM bus as well as separate control information. High quality
faxing is possible since no VoIP technology is involved between PSTN and FXS ports.
2.3.4 ISDN and Analog Interfaces
Positions of analog and digital interface connectors are shown in this picture (rear view):

For BRI ports a separate Y-cable must be used if more than two BRI lines are needed.
Notee!
▼
Never use PRI 2 without PRI 1 – if only one PRI interface is connected always use PRI
1, otherwise clock synchronization will not worke!
