Configuring the Subscriber Table
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.
About Subscriber IDs
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.
TIP
The Subscriber Table applies to all serial ports, regardless of protocol; however, it is only
available on devices running Þrmware version 3.3.0 or later.
