"This object is used to provision the jitter buffer mode

The possible values are:

'fixed' : means use a constant jitter buffer size, which

|
is defined by the vismJitterInitialDelay
|
|
(specify in CISCO-VISM-MODULE-MIB MIB) variable.
|
|
The DSP will be instructed to use fixed
|
|
with no time-stamps mode.
|
|
'adaptive': means let the DSP pick the optimal value for
|
|
the call connection.
|
|
|
|
'fixedWithTimeStamp': means use a constant jitter
|
|
buffer size, which is defined by the
|
|
vismJitterInitialDelay variable. The DSP
|
|
will be instructed to use fixed with
|
|
time-stamps mode.
|
|
|
|
For 'g711u', 'g711a', 'clearChannel', and 'lossless'
|

the default value is fixed.

DESCRIPTION
|
|
"This object defines the jitter buffer size in milliseconds.
|
|
If the vismCodecJitterDelayMode is set to be 'fixed',
|
|
the jitter buffer is fixed at this value for the duration
|
|
of the call, if it is set to 'adaptive', the value of
|
|
this object is the initial jitter buffer size, and the
|
|
DSP will adapt to an optimal size dynamically.
|
|
|
|
For G.711u, G.711a, Clear Channel, the default value is
|
|
100 ms.
|
|
|
|
For lossless the default value is 16ms.
|
|
|
|
For 'g726r32000', 'g729a', 'g729ab', 'g726r16000',
|
|
'g726r24000','g726r40000', 'g723h','g723l',
|
|
'g723ah' and 'g723al' the default value is 60 ms.
|
|
|
|
The jitter buffer size of this object differs for each set of
|
|
codecs supported on VISM card. A set of codecs supported
|
|
is identified by vismCodecTemplateNum object(defined in
|
|
CISCO-VISM-CODEC-MIB MIB).
|
|
|
|
For codecs in template number 1, 3, 4, and 5:
|
|
the jitter buffer size is as follow: 'zero', 'five', 'ten'
|
|
'fifteen', 'twenty', 'thirty', 'fourty', 'fifty', 'sixty',
|
|
'seventy', 'eighty', 'ninty', 'hundred'.
|
|
|
|
For codecs in template 2, the jitter buffer size
|
|
is as follow: 'zero', 'five', 'ten', 'fifteen', 'twenty',
|
|
'twentyfive', 'thirty', 'thirtyfive', 'fourty', 'fortyfive',
|
|
'fifty', 'fiftyfive', 'sixty', 'sixtyfive', 'seventy',
|
|
'seventyfive', 'eighty', 'eightyfive', 'ninty', 'ninetyfive',
|
|
'hundred'.
|
|
|
|
When the codec template changes, the value of this
|
|
object will be implicitly set to the default value.
