You can network the Phone Line Managers together to provide additional IST
device ports, telephone line ports, or both. The method you choose to
network the units together depends on the quantity of IST devices, the
telephone line use, and the application.
NOTE
The following diagrams use 4 x 12 Phone Line Manager units. The same
connections apply to 4 x 12 or 8 x 24 units. If you have questions about
your network application, please call Black Box Technical Support.
Example 1: Providing Additional IST Device Ports
When an application requires more IST ports than one Phone Line Manager
can provide, you can network two or more Phone Line Managers together.
Simply connect IST ports on the first Phone Line Manager to the line ports
on the second Phone Line Manager. Providing more than one network
connection between the two Phone Line Managers will permit more than one
IST device on the second Phone Line Manager to simultaneously access the
telephone lines on the first Phone Line Manager. A 3 to 1 ratio of devices to
lines is typical, although your particular application may be different. The
goal is to be able to provide dial tone and outbound call capability to all
outbound IST devices, while maintaining inbound call availability for those
applications and IST devices that require it. Networking two 4 x 12 Phone
Line Manager units together in this manner will create a 4 x 20 Phone Line
Manager. Networking two 8 x 24 Phone Line Managers together creates an 8
x 40 Phone Line Manager, while networking three 8 x 24s will create an 8 x 56
Phone Line Manager.
