Announcement Boards

announcement board capacities in cm
Posted: 2 Jun 09 (Edited 26 Jun 09)

tn750, tn750b, tn750c are limited to total seconds on each board of 255.
tn750, tn750b must be saved to individual tape, flashcard, removable media, disk
if you unplug tn750, tn750b all announcements are lost but can be restored to if
the correct media is available to restore from.
tn750c has memory on the board and does not lose announcements when unplugged.
The board can be saved for maintenance backup and restore, the same as the other
tn750 boards. The tn750c must be erased to clean off the board.
--------------------------------------------------------------------------------
example of finding time on each type val when a new board is inserted it shows
the max time under Time Remaining.

Max times below are estimates:

sec     min         type        min
---  ------         -----       ----
255  Max  4 minutes tn750  with 0.25 minutes for overhead
4032 Max 60 minutes tn2501 with 7.25 minutes for overhead
1376 Max 20 minutes g700   with 3.00 minutes for overhead
2848 Max 40 minutes g450   with 7.28 minutes for overhead
373  Max 15 minutes g350   with 1.50 minutes for overhead
913  Max 15 minutes g250   with 0.25 minutes for overhead

Overhead is space on the board to support the filesystem commands like
"list directory /annc board 1c17" and the "ftp" commands to view data.

The G250/G350 stores announcement files in an internal announcement directory.
The G250/G350 supports up to 256 announcement files, totalling up to 15 minutes
of audio for announcements and music on hold. Recording, storing, and playing
announcement files is controlled by Avaya CM.

The G250/G350 supports:
Secure transfer of announcement files to and from VAM using SCP
Simple management operations for the announcement files stored in the
announcement
--------------------------------------------------------------------------------
Announcement capacities and load balancing
Understanding how Communication Manager handles annoucements helps with
questions of capacity the load-balancing of announcement traffic. The Avaya
S8700 Series and S8300 media servers support up to 3,000 announcements across
the Communication Manager system. Each of as many as 10 integrated announcement
boards (and each G700 virtual VAL source) is limited to 256 announcements.

If you are running Communication Manager 4.0 or later, and have a S8720 system
with increased capacities configuration, you can have up to 128 VAL boards
(TN2501) and 250 VAL sources per system for a total of 378 announcement sources.
VAL boards are a RTU (right to use) feature. New limit is 1024 per valboard.
If you have a system that does not support increased capacities, the limit
remains at 10 TN2501 VAL boards.

Maximum Announcements per TN2501 Board (Firmware
17 or later otherwise limited to 256)

cm4 and higher is up to 1024 per board

http://support.avaya.com/elmodocs2/comm_mgr/r5_1/03-300511_5.1.pdf

All G700 Media Gateways in the system can be assigned as VAL sources, for a
maximum of 250 G700 VAL sources in a large S8700 Series media server
configuration also with up to 10 TN2501 VAL boards, providing an ultimate
capacity of 260 sources for the Avaya S8700 Series servers. TN2501 has 31
playback ports (with 60 minutes of storage capacity) and each G700 VAL
source has 15 playback ports (with 20 minutes storage capacity). Initially each
caller that is to hear a non-barge-in announcement on that source is connected
to an available port until each port has one caller connected. Initially 31
callers can be hearing an announcement from a single
TN2501 board (15 with a G700 VAL source). The same announcement can be playing
from multiple ports, each starting at a different time. Once all ports are busy
playing announcements, subsequent callers that are to hear an announcement
residing on that board/source are queued for that source.
Communication Manager queue size over all integrated announcement
sources is 4,000 callers (S8700 Series/S8300 media servers). When a port becomes
available, all callers (up to 1,000) waiting in the queue for a specific
announcement on that source are connected to the available port to hear the
announcement play from the beginning on a first-in, first-out basis.
At any given time you can have as many as 1,000 callers hearing the same
announcement on a given port of a board/source, yielding a (theoretical,
system-wide) capacity of 31,000 callers connected to a VAL board (or 15,000callers connected to a G700 Media Gateway virtual VAL source).
Factor in barge-in announcements which continuously play from a single port
(that can have as many as 1,000 callers connected at the same), and this
provides a very, very large capacity for playing announcements.
The measurements announcements commands can be used to monitor the system and
help determine burst conditions, allowing for better load balancing of the
traffic.
--------------------------------------------------------------------------------
Non-Volatile Storage of Announcements on VAL
The VAL board has a RAM based file system on which the announcements are stored.
This is where a newly recorded or FTP'd announcement resides. The VAL constantly
checks to determine whether changes have been made to the file system (file
added or deleted or renamed). Once a change has been detected, the VAL waits for
5 minutes of stability. After such a stable period, the VAL backs up the RAM
based file system to its FLASH. The FLASH version of the file system is
non-volatile and is what is restored upon reset/reseat. If you record a new
announcement and immediately reset the board, the announcement will be
lost. The yellow LED blinks while a backup from RAM to FLASH occurs. All of the
above is true regardless which (if any) of the .wav files on the board are
administered announcements. It is just the way the board (firmware) operates.
Note that only files with a .wav extension in the /annc directly are backed up
to FLASH.
