TN568 DEFINITY AUDIX 4.0 Voice Mail System (part of
ED-1E568)
Note:
Note: This circuit pack is no longer sold.
The TN568 circuit pack is a component of the ED-1E568 t. The TN568 supports an DEFINITY
AUDIX voice mail system using an embedded 386EX processor. The DEFINITY AUDIX
systems can be interconnected. Interconnected systems create large voice mail networks that
support up to 100,000 subscribers and store up to 100 hours of messages. Each circuit pack
has eight ports available for calls when networking is enabled. Without networking, 12 ports are
available.
The TN568 DEFINITY AUDIX voice mail system takes up two adjacent slots.
The TN568 DEFINITY AUDIX circuit pack includes a writable magneto-optical disk drive for
backing up and upgrading system software. The circuit pack also has a hard disk for storing
messages. The TN568 DEFINITY AUDIX circuit pack also includes an:
● RS-232 connection for a maintenance and administration terminal,
● Ethernet port for the Message Manager PC desktop application,
● Amphenol connection to the switch, and
● RS-232 port for an external modem that is used for maintenance.
TN570D Expansion Interface
The TN570 Expansion Interface (EI) is an interface between the TDM bus and the packet bus,
and fiber-optic links that interconnect the cabinets. The TN570D circuit pack is used in a port
network (PN) between a PN and another PN in a direct-connect system. The TN570D is also
used between a PN and a switch node interface (SNI) in a switch node carrier in a
CSS-connected system.
The TN570 circuit pack provides control-channel applications and time-slot interchanging
between the processor port network (PPN) and expanded port networks (EPNs). The TN750 is
used when ISDN-BRI, ASAI, or both are connected in an EPN.
The TN570 circuit pack carries:
● circuit-switched data,
● packet-switched data,
● network control,
