Description

 

 

 

 

Dynamic Jitter (cont’d)

 

 

 

 

 

Minimum

 

60 to 400 ms

The minimum dynamic jitter buffer of 60 milliseconds is

Jitter Value

 

 

the minimum delay that would be acceptable over a low

 

 

 

jitter network.

 

 

 

Default = 150 msec

 

 

 

 

Maximum

 

60 to 400 ms

The maximum dynamic jitter buffer of 400 milliseconds is

Jitter Value

 

 

the maximum delay tolerable over a high jitter network.

 

 

 

Default = 300 msec

 

 

 

 

Optimization

 

0 to 12

The Optimization Factor determines how quickly the

Factor

 

 

length of the Dynamic Jitter Buffer is changed based on

 

 

 

actural jitter encountered on the network. Selecting the

 

 

 

minimum value of 0 means low voice delay is desired,

 

 

 

but increases the possibility of jitter induced voice quality

 

 

 

problems. Selecting the maximum value of 12 means

 

 

 

highest voice qauality under jitter conditions is desired at

 

 

 

the cost of increased voice delay.

 

 

 

Default = 7.

Automatic

The Automatic Disconnection group provides four

Disconnect-

 

 

options which can be used singly or in any combination.

ion

 

 

 

 

 

 

 

Jitter Value

 

1-65535

The Jitter Value defines the average inter-arrival packet

 

 

milli-seconds

deviation (in milliseconds) before the call is automatically

 

 

 

disconnected. The default is 300 milliseconds. A higher

 

 

 

value means voice transmission will be more accepting of

 

 

 

jitter. A lower value is less tolerant of jitter.

 

 

 

Inactive by default. When active, default = 300 ms.

 

 

 

However, value must equal or exceed Dynamic

 

 

 

Minimum Jitter Value.

 

 

 

 

Call Duration

 

1-65535 seconds

Call Duration defines the maximum length of time (in

 

 

 

seconds) that a call remains connected before the call is

 

 

 

automatically disconnected.

 

 

 

Inactive by default.

 

 

 

When active, default = 180 sec.

 

 

 

This may be too short for most configurations, requiring

 

 

 

upward adjustment.

 

 

 

 

Consecutive

 

1-65535

Consecutive Packets Lost defines the number of

Packets Lost

 

 

consecutive packets that are lost after which the call is

 

 

 

automatically disconnected.

 

 

 

Inactive by default.

 

 

 

When active, default = 30

 

 

 

 

Network

 

1 to 65535 seconds;

Specifies how long to wait before disconnecting the call

Discon-

 

Default = 30 sec.

when IP network connectivity with the remote site has

nection

 

 

been lost.
