Additional Remote Networking Reducing Cost
5-11
5.5.3 Reducing the Number of Ports Used
When additional links are brought up to increase bandwidth, phone charges will increase. Reducing the
number of ports or reducing the site’s maximum bandwidth can reduce total cost; see Purge Site on page
12-150 and Define Site Bandwidth on page 12-136 for details.
5.5.4 Using Higher Speed Modems
The time used to transfer data can be reduced by using the highest speed modems available. To ensure that
high speed modems are used before low speed modems, priority numbers may be assigned to each site’s
ports. If high speed modems are attached to ports with high priority numbers, they will be dialed before
other modems.
5.5.5 Restricting Connections to Particular Times
Sites can be configured to permit outgoing connections only within particular time ranges on particular
days. For example, outgoing connections can be restricted to Monday through Friday, between 9 a.m. and
5 p.m.
5.5.5.1 Determining if Site Restrictions are Appropriate
Sites don’t need to be configured to restrict connections; applications can be restricted to run only at
particular times. Before configuring a site, it is important to consider whether it’s appropriate for a remote
application or an SCS site to control the access restriction.
5.5.5.2 Setting Up Site Restrictions
To configure a time range, use the Define Site Time Add command. The time range may be within one day,
or may span from one day to another day. (If a second day isn’t specified, the time period is assumed to take
place entirely on the first day specified.) The beginning and end times of the range must be specified in 24-
hour format. Some examples are displayed below.
Figure 5-18: Adding Time Ranges
Note: Up to ten time ranges may be specified.
Next, specify whether connections will be permitted or prevented during these times using the Define Site
Time Default command. Enabled permits outgoing connections, except during the time ranges stated.
Disabled prevents outgoing connections, except during the time ranges stated.
Figure 5-19: Enabling Connections During Time Ranges
Configurable time ranges are based on a Sunday-to-Saturday week. To configure access that spans weekend
hours, see Controlling Access During Weekend Hours on page 5-16.
