BASE DATA RATE
Only used for outbound calls. This value represents the data rate of one channel. The data rate can
be specified as either 56,000 or 64,000 bps. A data rate must be defined for each remote device that
will be dialed. The initial data rate and the maximum data rate configuration elements must also
be configured for the Callable feature, and are used in combination with the base data rate. The
default configuration for the base data rate is 64,000 bps.
I
NITIAL BANDWIDTH
Only used for outbound calls. The initial bandwidth determines the number of calls that will be
attempted when opening the first wide area connection. This provides you with a mechanism to
request that a group of parallel connections be made to a remote device rather than a single
connection. This will allow data to begin to flow at greater rates without waiting for the
Throughput Monitor to detect an overload condition. Calls will be made until an additional call
would exceed the configured value. The value is configured as a number from 0 bps to 999,999,999
bps. You may configure any value in this range. For example, if you have configured the base data
rate at 64 Kbps, and the initial bandwidth at 256,000, the system would attempt to initially use four
calls (connections) running in parallel (256,000 / 64,000 = 4). The value need not be a multiple of
the base data rate. The default configuration for the initial bandwidth is 64,000 bps.
M
AXIMUM BANDWIDTH
The maximum data rate is used to limit the total number of channels that can be committed to a
single logical connection. This sets an upper boundary for line and capacity utilization. This upper
boundary allows you to keep one remote device from crowding out other users and using an unfair
share of available resources. This parameter is enforced on inbound and outbound calls. The
system will not accept or make a call when the added bandwidth will exceed the configured
maximum. The value is configured as a number from 0 bps to 999,999,999 bps. You may configure
