ANALOG VOICE I/O CARD
The Analog Voice I/O Cards, which mount on the motherboard in any of slots 1-8,
enable the CX950 to transmit and receive voice and fax data. Each card supplies a
single analog voice/fax port controlled by a Line Interface Driver (LID).
WARNING:
The Analog Voice I/O card
cannot coexist
with the following cards in
the same CX950 chassis:
- Dual Analog Voice I/O Card (DAV I/O)
- BRI Digital Voice I/O Card (BRI-DV I/O)
- Digital Interface Module (DIM) I/O Card (when used for voice)
The Analog Voice I/O Card requires a -48V/Ring Generator card to be mounted
on the motherboard.
NOTE:
To Our Users in Australia
According to the certification requirements of the Australian TeleCommuni-
cations Authority, we advise you that:
When connecting the Analog Voice I/O card via FXO, FXS, E&M 2-wire, or
E&M 4-wire LIDs, you should only use CCL listed interconnection cables as
they adhere to technical standard TS 008.
When using E&M 2-wire LIDs, you should only use drivers with 600 Ohms
complex impedance (Australian Complex).
