An analog-line interface card is
required in all system configurations. The analog-line
interface card supported for use with INTUITY AUDIX LX is a four-port
card that supports both voice and fax.
For information on removing and installing analog-line
interface cards, see Replacing an Analog-line
Interface Card.
Standard Configuration
The standard configuration includes
one analog-interface card with four ports enabled. The maximum supported
configuration is three analog-line interface cards with 12 ports enabled.
The analog-line interface cards are placed in the slots numbered PCI
5 through PCI 3, from the bottom to the top (see Back
View of Platform, and Internal Layout of Platform.
Hardware Switches
The switches that must be set on the interface cards for
the INTUITY AUDIX LX system are the ID, the hook-switch state, and the
Computer Telephony (CT) Bus jumpers. These switches are preconfigured
on new INTUITY AUDIX LX systems:
- The ID is a sequential
number that specifies the device and channel names to use for each
card. The ID is assigned using the SW30 rotary switch located at the
top of the card.
- The hook-switch state
determines how the card responds to an incoming call when the card
is not initialized. The hook-switch state is set using the SW4
switch located near the top of the card. You should always set
the hook-switch to On (off-hook) so that callers hear a busy signal
when the card is not initialized.
- If more than one analog-line interface card is installed in a system,
you must set the CT Bus jumpers. The CT Bus provides communication
and resource sharing among the installed cards. Terminate the JP2
jumper on both cards in a two-card configuration or on cards one and
two in a three-card configuration. See Installing
an Analog-line Interface Card for detailed information on setting
the J2 jumper correctly.
Cabling Multiple Analog-line Interface Cards
If multiple cards are installed in a system, use a CT
Bus cable to connect the cards. See Installing
an Analog-line Interface Card for detailed information on cabling
multiple cards.
On INTUITY AUDIX LX systems ordered with multiple cards,
the cards are already cabled.
Connecting Phone Cables
Each analog-line interface card has four
RJ-11 jacks on the rear bracket, numbered J1 through J4. Use the
RJ-11 jacks to connect each channel to a PBX.
