About the Subscriber Table and Subscriber IDs; accessing the Subscriber Table window; adding or 
modifying a subscriber table entry; editing the Routing and Address tables

The Subscriber Table allows you to add or modify the entries your FRX or 
SmartSwitch 1800 will use to establish virtual connections to end-user devices in 
the network. These entries contain the assigned subscriber addresses, as well as 
information that links those addresses to a speciÞc FRX or SmartSwitch 1800 
physical or logical port (or ports). Entries also contain additional information 
related to preferred delivery algorithms, alternate routing paths, and transmission 
priority.

Your FRX and SmartSwitch 1800 devices are designed to provide point-to-point 
dedicated connections among the devices communicating through their serial

ports. There are two types of connections used to accomplish this: Permanent 
Virtual Circuits, or PVCs, which deÞne permanent point-to-point connections 
which are always available, even when they are not being used; and Switched 
Virtual Circuits, or SVCs, which are established and broken in response to speciÞc 
call requests.

Subscriber IDs are used to establish virtual connections between the FRX and 
end-user devices (or subscribers) in the network. A Subscriber ID is associated 
with at least one physical or logical port on your FRX or SmartSwitch 1800 device, 
and includes a number of parameters related to how call requests are routed to 
that subscriber. The Subscriber Table allows you to conÞgure this subscriber 
information.
