•
Conferencing resources for connecting up to 12 parties in multiple conferences. There
can be up to three simultaneous four-party conferences or up to four simultaneous
three-party conferences. Conferencing is not amplified.
•
DTMF receiver circuits provide circuits (two for non-ATM cards; six for ATM cards)
that are used when single-line sets connected to MDPMs are dialing and when features
such as DISA and analog voice mail are used. These receivers convert DTMF signals to
the digital codes used by the system. They are in use only while the dialed number is
being processed, not for the duration of the call. If all DTMF receivers are busy, the
user may try again (DISA users are redirected to the primary attendant).
•
DTMF transmitter circuits (two) generate DTMF tones whenever needed by the sys-
tem. For example, when a Basic, Standard, or Associate Phone user manually dials a
number while on a call or when a station user uses one of the system auto-dial features
(ARS, call forward to the public network, station or system speed dial, etc.). Executive
Display and Professional Display Phones can generate their own DTMF tones.
•
Tone generating circuit produces all of the system tones (busy, reorder, do-not-disturb,
etc.) heard by phone, single-line set, DISA, and automated attendant users.
B. INSTALLATION
3.8
Install the CPU64 as follows:
Check the part number and socket number printed on the feature-unit PAL. They must
1.
match the software configuration purchased by the customer, their labels should have
the correct part number, and they should be installed in socket number U4. (The boot
ROM and memory map PAL are already installed on the card.)
Place the CPU64 Card on a clean, flat, anti-static, non-conductive surface.
2.
Carefully install the feature unit PAL in the socket marked "Feature Unit PAL" on the
3.
card. (See
pin 1 must match the notch of the outline silk-screened on the card.
NOTE:
Check that all components on the card are seated securely in their sockets and that no
4.
pins are bent.
Install the CPU64 Card in the equipment chassis as follows. See

for an illustration of the card.
Ensure that all integrated circuits and components on the card are seated securely
in their sockets and that no pins are bent.
Ensure that the mu-law/a-law jumper (J14) is in the correct position for your
installation (U.S. installations use mu-law).
Place the battery back-up (BATTERY - J2) jumper strap in the ON position to
enable database battery back-up. If the jumper strap is placed in the OFF position,
the BATTERY OFF LED lights when the card is installed and AC power is on.
NOTE:
The BATTERY OFF LED will not light if the jumper strap is missing.
