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 de.ne 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 speci.c 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 con.gure this subscriber information. Configuring the Subscriber Table Accessing the Subscriber Table To launch the Subscriber Table: 1. In the Hub View, click on the button to display the Device menu. 2. Drag down to Subscriber Table, and release. The Subscriber Table window, Figure 4-1, will appear. Figure 4-1. The Subscriber Table Window 4-2 Accessing the Subscriber Table Configuring the Subscriber Table The Subscriber Table window contains three main areas: the Subscriber Table itself (in the top half of the window), which allows you to add, modify, or delete subscriber entries; the Routing Table (on the lower left), which allows you to assign one or more routing paths to a subscriber entry by associating that entry with one or more physical or logical ports on your device; and the Address Table (on the lower right), which allows you to assign the addresses that will be used for call redirection (if those options are speci.ed in the table entry). Each of these tables is described below. TIP If no Close button appears in your window, use the scroll bar to the right of the display to access the button, which is at the bottom of the window. Configuring the Subscriber Table The Subscriber Table displayed at the top of the window is the main table that allows you to de.ne the subscribers who will be communicating across your FRX or SmartSwitch 1800 device. To con.gure a Subscriber Table entry, you must set the following parameters: Subscriber ID Each subscriber is identi.ed by an ID, or address, of up to 15 digits. When assigning or editing a Subscriber ID, keep the following in mind: • Subscribers using a public data network (PDN) must conform to the format used by the PDN. (A PDN is a network operated by common carriers or telecommunications administrations for the purpose of providing data transmission capabilities to the public.) For example, CCITT recommendation X.121 speci.es a format which includes a one-digit international code, followed by a four-digit Data Network Identi.cation Code (DNIC), followed by up to 10 digits of Network Terminal Number (NTN). • A private network N one that will not communicate with other networks N can create its own format, using any or all of the available digits as desired. Since each FRX or SmartSwitch 1800 port can support multiple subscribers, Subscriber IDs can also use wildcard characters so that all subscribers on a port can be referenced with a single entry. Two wildcard characters are available: • A question mark (?) in a subscriber ID matches any single digit. For example, 3110?????????? matches any 14-digit address that begins with 3110. • An asterisk, or star (*), matches any combination of digits, including none at all. For example, 3110*00 is any address that starts with 3110 and ends with 00, including 311000 but excluding 31100 (overlapping is not allowed). An asterisk by itself matches any address. Wildcard characters can also be combined: the address 3110??* matches any address that begins with 3110 and contains at least two more digits. Configuring the Subscriber Table Configuring the Subscriber Table Algorithm The algorithm .eld allows you to select the means by which call requests are forwarded to one of several routing paths assigned to the named subscriber. You can select from among four options: Round Robin As its name implies, this algorithm selects ports cyclically in numeric order (as con.gured in the Routing Table). If a selected port is unreachable or congested, call requests are forwarded on to the next port in sequence. Line Failed The Alternate Route on Line Failure algorithm selects the .rst listed port that is not in a failed state. If the selected port does not make the connection, the call request will be cleared, even if other ports are available. Line Busy The Alternate Route on Line Busy algorithm selects the .rst port that is not busy. If that port has failed, the next available port will be selected. Least LCN The Least LCN with Throughput algorithm selects the line with the smallest load, calculated using the weight (speed) and number of virtual circuits in use on that line. ...
