TN568 Circuit Pack

The TN568 circuit pack holds the systems main circuitry and performs system’s main processing functions, including message routing, self-diagnosis, and Alarm Origination.

Port Board Emulation

The TN568 holds the system’s voice ports. These voice ports correspond to the voice ports on a TN754 or TN2181 circuit pack. DEFINITY switch releases 7.1 and later recognize the TN568 circuit pack. However, the system’s voice ports interact with the switch like the voice ports on a TN754 or TN2181 circuit pack regardless of whether the system is operating in native or non-native mode. For more information about digital port emulation, see Chapter 1.

Flashware

The TN568 circuit pack uses flashware to store the sequences it uses to boot the system and programs specific to the TN568. Flashware are programs that reside on flash programmable read-only memory (FPROMs). FPROMs are hardware that reside on the TN568 and are protected from accidental erases or rewrites. Copies of all the active flashware programs are also stored on the hard disk.

If the customer installs software upgrades or fixes, the new program is transferred from a MO disk to the hard disk. When the system reboots, the new program automatically transfers from the hard disk to the FPROMs and replaces the existing flashware.

Hard Disk Drive

The hard disk drive stores the system’s AUDIX software, subscriber information and voice messages.

Voice messages that customers may store on the system include voice mail, personal greetings, automated attendants, and announcement sets—the sets of automated, verbal instructions that compose the system’s user interface.

The hard disk drive provides up to 100 hours of voice storage. The system comes with a minimum of 10 hours of voice storage. Customers can purchase additional voice storage in five-hour blocks.
