User's Manual
Description
Defines the rate at which tokens are added to
the token bucket per second (i.e., token rate).
One token is added to the bucket every 1000
divided by the value of this parameter (in
milliseconds).
The default is 0 (i.e., unlimited rate).
Note: The token bucket feature is per IP
Group, SRD, SIP request type, and SIP
request direction.
Defines the maximum number of tokens (SIP
dialogs) that the bucket can hold. The device
only accepts a SIP dialog if a token exists in
the bucket. Once the SIP dialog is accepted, a
token is removed from the bucket. If a SIP
dialog is received by the device and the token
bucket is empty, then the device rejects the
SIP dialog. Alternatively, if the bucket is full,
for example, 100 tokens, and 101 SIP dialogs
arrive (before another token is added to the
bucket, i.e., faster than that defined in the Rate
field), then the device accepts the first 100 SIP
dialogs and rejects the last one.
Dropped requests are replied with the SIP 486
"Busy Here" response. Dropped requests are
not counted in the bucket.
The default is 0 (i.e., unlimited SIP dialogs).
Note: The token bucket feature is per IP
Group, SRD, SIP request type, and SIP
request direction.
Defines the guaranteed (minimum) call
capacity.
Notes:

An IP Group ID or SRD ID must be
specified when this parameter is configured
and the IP Group or SRD cannot be set to
all (-1).

Reserved call capacity is applicable only to
INVITE and SUBSCRIBE messages.

Reserved call capacity must be less than
the maximum capacity (limit) configured for
the CAC rule.

The total reserved call capacity configured
for all the CAC rules must be within the
device's total call capacity support.
