Audio Information Exchange (AUDIX)
Interface Option Settings for G3i
Systems
AUDIX is sometimes connected to the switch through the processor interface
circuit pack. The first circuit on the processor interface can be connected directly
to the AUDIX through the PROCESSOR INTERFACE connector on the rear of
the control carrier. Any of the remaining three circuits on the processor interface
to be used to support AUDIX must be connected through a modular processor
data module (MPDM) serving as the interface link for AUDIX. The option settings
recommended for the modular processor data module (MPDM) in this
application are shown in Table H-26.
TN760 Tie Trunk Circuit Pack Option
Settings
The TN760 circuit pack interfaces between four 6-wire tie trunks and the time
division multiplex (TDM) bus. Two tip and ring pairs form a 4-wire analog
transmission line. An E and M pair is used for signaling. The E and M pair are
direct current signaling leads used for call setup. The E lead receives signals
from the tie trunk and the M lead transmits signals to the tie trunk.
To choose the preferred signaling format (Table H-30 and Table H-31), set
switches on the TN760 circuit pack and administer the port per Figure H-2 and
Table H-29.
