The AWAN access server’s dial-out feature enables Macintosh, DOS, and Windows-

based computers on the local network to use an internal or external modem connected to

the AWAN access server. By using the proper software, the workstation can use the

AWAN access server to dial out to a remote system, commercial services, or bulletin

board service (BBS). The dial-out feature can eliminate the cost of equipping each

workstation with a modem and providing access to a second telephone line.

Sample Configuration

Figure 11-1 shows an AWAN access server in a dial-out configuration. In this example,

personal computers (PCs) on the local area network (LAN) can access resources

elsewhere in the network using modems connected to the AWAN access server.

How It Works

Internet Protocol (IP) network users establish a Telnet connection and Novell NetWare

users establish a NetWare Asynchronous Services Interface (NASI) connection with an

internal or external modem on the AWAN access server. IP network users can also use

Telnet to reach a pool of modems for dial-out. After the connection is made to the

modem, a workstation user can use the modem as if it were directly connected to that

user’s computer.

To establish a dial-out connection, a TCP/IP or NASI stack must be installed on the local

computer along with the appropriate terminal emulator or telecommunications software.

Data from the local computer is sent to the Ethernet port on the AWAN access server

and routed to the selected dial-out port.

Note. All AWAN access server ports can be shared between dial-in and dial-out applications.
