| announceMIBCompliance | 1.3.6.1.4.1.351.150.25.3.1.1 | | | The compliance statement for the Media Gateway Card
Announcement group which implements cwAnnounceGeneric MIB. |
| ciscoWanAnnouncementMIB | 1.3.6.1.4.1.351.150.25 | | | The MIB module is defined to configure the Announcements
feature on the Media Gateway Card.
The Media Gateway Card will have the capability to
play pre-recorded local announcements in switched
VoIP solutions only. Under the control of a call agent,
announcements can be played in either direction over
existing connections (calls) or towards the Time
Division Multiplexed (TDM) network on a TDM endpoint
that is terminated on the the Media Gateway Card.
A large number of different announcements may be cached
on the Media Gateway Card for immediate play out.
A persistent announcement store, called the Announcement
file server, will exist in the packet network and hold
all the announcements in the network. Announcements will
be downloaded on demand as announcement files from
the configured announcement store. Downloaded announcement
files will be stored on the Media Gateway Card as either
'permanent' or 'dynamic' announcement files. Permanent
files on the Media Gateway Card are exempt from being
refreshed, replaced, or removed without explicit
provisioning actions. Dynamic announcement files will
not persist across resets. Permanent announcement files
will be reloaded, if possible, following a reset. Dynamic
announcement files are automatically 'aged'. 'Aged'
files are re-fetched from the Announcement file server.
Dynamic Announcement files can be replaced on the
Media Gateway Card if the Announcement memory on the
card is full and additional Announcement files are to
be downloaded. The file(s) to be replaced will be
determined according to some Least Recently Used(LRU)
algorithm.
Announcements can be played over established connections
and unconnected TDM endpoints in any encoding supported
by the Media Gateway Card in its current configuration.
Announcement files must be encoded in G.729a to be
played on G.729ab connections or, if G.729ab has been
chosen as the preferred codec, unconnected endpoints.
The Announcement file server will reside on an IP network
reachable from the Media Gateway Card using TFTP.
The user will configure the Announcement file server
node name on the the Media Gateway Card.
The Announcement file server will have a 'main' file
directory for Announcements. If the Announcement prefix
path is configured to begin with a '/' then the
directory is absolute. If the prefix path is configured
to begin without a '/' then it will be relative to the
default TFTP server directory. If no prefix path is
configured then the Announcement 'main' directory and
the TFTP default directory will be the same. The user
must configure subdirectories within the main
Announcement directory for each encoding that
Announcements may be played in. These subdirectories must
be of the following names: 'g711u', 'g711a', 'g726_40k',
'g726_32k', 'g726_24k', 'g726_16k', 'g729_a',
'g7231_high_rate', 'g7231_a_high_rate', 'g7231_low_rate',
'g7231_a_low_rate'.
The Media Gateway Card maintains an Announcement cache in
resident memory. The cache is populated on demand with
dynamic files or provisioned with permanent files. That
is to say that when an Announcement is requested to be
played it will first be retrieved from the Announcement
file server and placed in the on-board Announcement cache.
Subsequent requests for the same Announcement will not
require retrieval of the Announcement file from the
Announcement file server. Note that an Announcement in
one encoding is a different file than the same
Announcement in a different encoding.
The 'Announcement aging' policy is provisionable for
dynamic files. Once a dynamic Announcement has 'aged'
in the on-board cache it will be 'refreshed' by being
retrieved again from the Announcement file server.
The age time determines the maximum time before an updated
Announcement file is automatically propagated to the card.
Shorter age times will result in more frequent file
server access. Changing the 'age' time does not affect
the age times of dynamic Announcement files currently
loaded. However, once these files are refreshed, they
will then use the new 'age' time.
Announcements may also be provisioned as 'permanent'.
A permanent Announcement will be fetched from the
Announcement file server and 'frozen' in the Media
Gateway Card Announcement cache. Permanent
Announcements will be excluded from aging (and being
automatically refreshed) and excluded from being
replaced if the Announcement cache becomes full.
Permanent Announcements can only be removed from the
cache explicitly by user through command line
interface or through a Network Manager. If the Media
Gateway Card is reset, permanent Announcements will be
re-fetched from the Announcement file server as soon
as the card becomes active. The Announcement encoding
must be specified when provisioning permanent
Announcements. |
| I32 cwAnnAgeTime | 1.3.6.1.4.1.351.150.25.1.1.1.3 | Integer32 | read-write | This object records the time in minutes for a dynamic
Announcement file in the cache to age.
The Age time is the configurable number of minutes before a
dynamic Announcement file in the Media Gateway Card
Announcement cache will be invalidated and refreshed
from the Announcement file server.
An Announcement file starts 'aging' as soon as it is
brought into the cache from the file server.
Zero (0) time specifies that the age time is infinite,
so that no aging will occur. But, unlike a permanent file,
a file with aging of 0 may be replaced. |
| ANN cwAnnFileCodec | 1.3.6.1.4.1.351.150.25.1.1.2.1.1.4 | AnnCodecType | read-create | This object records the codec associated with a specific
Announcdement file.
The default will be the value specified in the
cwAnnPreferenceCodec MIB object above. |
| STR cwAnnFileName | 1.3.6.1.4.1.351.150.25.1.1.2.1.1.3 | DisplayString | read-create | This is the name of a valid Announcement file which has
been stored in the Announcement table as a permanent
Announcement File name. This file name may include path
or subdirectory information.
The individual characters in this name may be alphanumeric
characters, forward slashes, backward slashes, periods,
dashes, and underscores, but no embedded spaces. Also,
the last character of the name must not be a dash or a
forward slash.
However, single underscore character ('_') is considered
a NULL string and should not consist cwAnnFileName name. |
| STR cwAnnFileServerName | 1.3.6.1.4.1.351.150.25.1.1.1.2 | DisplayString | read-write | This object records the name of the Announcement file
server.
The individual characters in this name may be alphanumeric
characters, forward slashes, backward slashes, periods,
dashes, and underscores, but no embedded spaces.
Also, the last character of the name must not be a
dash or a forward slash.
The default value for this MIB object is a 'null'.
If the Announcement file server name is not configured,
Announcements cannot be downloaded.
The 'null' value of this field is a single space character,
which may be set to this value by setting this MIB object to
the single character space string (' ').
Alternatively, for computing systems that cannot handle
single character space strings, the single character
('_') underscore string may be used as an alternative
'null' value, which would then be converted internally to
the single character space string.
Before the Announcement file server name may be successfully
configured, the name must first be added to the list of
domain names (mgDomainName) contained in the
mgDomainNameTable(defined in CISCO-WAN-MG-MIB MIB).
If the domain is configured for internal resolution, then
the file server name must be asssigned an IP address
to be put in the mgcResolutionTable(defined in
CISCO-WAN-MG-MIB MIB). |
| INT cwAnnFileStatus | 1.3.6.1.4.1.351.150.25.1.1.2.1.1.2 | INTEGER | read-only | This attribute specifies the status of this entry
regarding to the permanent Announcement file name
in cwAnnFileName MIB object:
'loaded(1)': successfully downloaded permanent file.
'loading(2)': in process of downloading a permanent file.
'invalidFile(3)': file on File server is too large or
corrupted.
'loadFailed(4)': timeout when trying to download a
permanent file.
When this entry is created with a valid permanent
Announcement file name in the cwAnnFileName MIB object,
this permanent status is set to 'loading(3)' while
background activities attempt to download the permanent
file from the Announcement FTP server. If this attempt is
successful, the permanent status is set to 'loaded(3)', but
if this process fails the permanent status is set to one
either 'invalidFile(3)', or 'loadFailed(4)'.
Once an entry is loaded, if a subsequent card reset
occurs the Media Gateway Card will attempt to restore all
of the configuration information by doing its normal
download of the latest MIB data base from the PXM
(Processor Switch Module) hard disk, set all
'loaded (2)' MIB objects to 'loading (3)', and then do
an background process to retrieve all of the Announcement
files from the Announcement file server, since this
information is not contained in the PXM. If this retrieval
of the Announcement files succeeds then this MIB object
will be set back to 'loaded (2)'. If this file retrieval
does not succeed, then this MIB object will be set to
one of: 'invalidFile(3)', or 'loadFailed(4)'. |
| I32 cwAnnMaximumSize | 1.3.6.1.4.1.351.150.25.1.1.1.1 | Integer32 | read-only | This object records the maximum size of the Announcement

| ANN cwAnnPreferenceCodec | 1.3.6.1.4.1.351.150.25.1.1.1.4 | AnnCodecType | read-write | This object records the codec to be used for playing
Announcements on an unconnected TDM endpoint.
The default will be 'g711u' for a T1 Media
Gateway Card, or will be 'g711a' for an E1
Media Gateway Card. |
| STR cwAnnPrefixPath | 1.3.6.1.4.1.351.150.25.1.1.1.5 | DisplayString | read-write | This object records the directory path under the default
TFTP directory in the Announcement File server for
announcement files.
The purpose of this MIB object is to specify the 'main'
directory for Announcements if it is to be different than
the default TFTP directory.
The individual characters in this name may be alphanumeric
characters, forward slashes, backward slashes, periods,
dashes, and underscores, but no embedded spaces. Also,
the last character of the name must not be a dash or a
forward slash.
If this MIB object is a 'null' value it will not cause any
directory path string to be inserted with the
cwAnnFileName MIB object.
The 'null' value of this field is a single space character,
which may be set to this value by setting this MIB object to
the single character space string (' '), or alternatively,
for computing systems that cannot handle single
character space strings, to the single character
('_') underscore string, which will then be converted
internally to the single character space string. |
| I32 cwAnnReqTimeout | 1.3.6.1.4.1.351.150.25.1.1.1.6 | Integer32 | read-write | This object records the time for a dynamic play Announcement
request to be serviced.
If the Announcement subsystem cannot start playing the
Announcement within cwAnnReqTimeout seconds since the
request was received, the play request will be aborted.
Zero (0) time specifies that the timeout time is infinite,
so that no timeout will occur. |
| ROW cwAnnRowStatus | 1.3.6.1.4.1.351.150.25.1.1.2.1.1.5 | RowStatus | read-create | Once a row is created, modification is not allowed on
the row.
cwAnnFileName MIB object is the mandatory parameter
for creating an entry in this table.
To delete an Announcement file entry, the RowStaus
will be set to 'destroy'. |
