Add Multiple Announcement
Return to Task List
TN750C and TN2501AP circuit packs are required if the system has more than one announcement circuit pack. No more than 1 TN750 or TN750B can reside in the system. The TN750C or TN2501AP can install in any port or service (TDM) slot, and need not reside in a control carrier for extra power holdovers.
This section provides information on
TN750C Announcement Circuit Pack
The TN750C circuit pack contains on-board flash memory which provides internal backup of announcements on the circuit packs. Thus, the TN750C circuit pack does not need the save and restore processes. However, you can use the save and restore processes to copy announcements from the TN750 or TN750B to a TN750C circuit pack.
The TN750C circuit pack can replace a TN750 or TN750B circuit pack. The difference in operation is that the TN750C circuit pack automatically restores and reports the availability of announcements from its own internal flash memory in 5 minutes, rather than the approximately 40 minutes for the TN750 or TN750B circuit pack reporting from the mass-storage system.
If a circuit pack already has announcements in its flash memory, the yellow LED flashes as the announcements copy to the Voice RAM.
TN2501AP Announcement Circuit Pack
The TN2501AP integrated announcement circuit pack
- offers up to 1 hour of announcement storage capacity.
- requires shorter backup and restore times.
- is firmware downloadable.
- plays announcements over the TDM bus, similar to the TN750C.
- has 33 ports, including
- 1 dedicated telephone port for recording and playing back announcements (port number 1).
- 1 ethernet port (port number 33).
- 31 playback ports (ports 2-32).
- 10/100 Mb ethernet interface, allowing announcement and firmware file portability over your LAN (FTP server functions).
- supports .wav announcement files (see Important File Specifications).
- works in r, si, csi, DEFINITY ONE, and Avaya IP600 models.
Important File Specifications
Voice Announcement over LAN (VAL) requires that announcement files are in the following .wav formats:
- CCITT A-Law or CCITT
µ-Law companding format (do not use PCM)
- 8KHz sample rate
- 8-bit resolution (bits per sample)
- Mono (channels = 1)
You must convert other wave ( .wav) file formats to those listed above. Telephone access creates the correct file formats.
Save and Restore Recorded Announcements
The syntax for saving from any TN750 circuit pack is
save announcements [from PCSS] and press
Enter. Where P is the port network number (1 for PPN, and 2-4 for EPN), C is the carrier designation (A, B, C, D, or E), and SS is the number of the slot in which the circuit pack resides (01 to 21).
The syntax for restoring to a TN750C circuit pack is
restore announcements [disk | removable media [to PCSS]] and press
Enter. Where P is the port network number (1 for PPN, and 2-4 for EPN), C is the carrier designation (A, B, C, D, or E), and SS is the number of the slot in which the circuit pack resides (01 to 21). When executing a restore command and there are existing announcements on the circuit pack, the following warning message appears:
After 5 minutes (with no alterations to the announcements), the TN750C automatically copies the announcements from the Voice RAM to the internal flash memory. The yellow LED on the front of the TN750C flashes.
You can only save the announcement contents of 1 circuit pack to mass storage at a time. For the contents of every circuit pack, save to separate translation cards. Label each card to match the circuit pack saved to it.
TN750 and TN750B Announcement Circuit Packs
The recorded announcements in the system can be saved on the mass-storage system by typing
save announcements spe-active/spe-standby and pressing
Enter. These commands should only be used after business hours or when the system is operating during a low-usage period. The system takes about 40 minutes to transfer the recorded announcements from the announcement circuit pack to the mass-storage system. During this time period, the management terminal cannot be used to administer the system until the transfer finishes; however, all other administration terminals, if provided, are allowed to perform administration procedures.
The recorded announcements in the system can be restored to system memory from the translation card by entering the
restore announcements command.
