Mediant 500 E-SBC
Parameter Description
Rate
CLI: rate
[SBCAdmissionControl_Rate]
Defines the rate (in seconds) at which tokens are added to the
token bucket per second (i.e., token rate).
The default is 0 (i.e., unlimited rate).
Notes:

You must first configure the Maximum Burst parameter
(see below) before configuring the Rate parameter.

The token bucket feature is per IP Group, SRD, SIP
request type, and SIP request direction.
Maximum Burst
CLI: max-burst
[SBCAdmissionControl_MaxBurst
]
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 480 “Temporarily
Unavailable” 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.
Reservation
CLI: reservation
[SBCAdmissionControl_Reservati
on]
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.
