Installation and Reference for the BayStack 820 ISDN Router BayStack 820 ISDN Router Overview The BayStack 820 ISDN Router is a small-sized desktop multi-purpose router for branch-to-branch Intranet access, dial-in local area network (LAN) access, and Internet access. The router has an ISDN interface, a four-port 10BASE-T repeater hub, and two voice adapter ports for connection to analog telephone or facsimile devices.

Page 34: Isdn Support
Installation and Reference for the BayStack 820 ISDN Router ISDN Support The BayStack 820 ISDN Router is specifically designed to take advantage of ISDN for transmission of data over digital telephone networks. A basic rate interface (BRI), which is the usual ISDN implementation, consists of two 64 kilobits per second (Kb/s) B channels for data and one 16 Kb/s D channel for control information.
Page 35: Branch-To-Branch Access
You can create a private wide area network (WAN) using two or more BayStack 820 ISDN Routers and enable two or more remote networks to connect to one another to share resources. Figure 1-1 illustrates how two BayStack 820 ISDN Routers support a WAN connection for branch-to-branch access. Your LAN #1 Figure 1-1.
Page 36: Remote Dial-In Access
Figure 1-2. Remote Dial-In Access You can configure the BayStack 820 ISDN Router to allow remote users to connect to your LAN and share resources when they are away from the office and stay productive they are at home or on the road.
Page 37: Internet Access
Internet Access The BayStack 820 ISDN Router provides Internet access so that everyone on your LAN can access the Internet and send and receive e-mail messages and files. The router uses single IP address technology that greatly simplifies configuration. When you establish a connection to the Internet, the router automatically acquires the necessary IP address.

VPN connection profile, the information in the Profile is used to authenticate the incoming call, and then data transfer begins. Figure 1-5 illustrates how the BayStack 820 ISDN Router supports a VPN tunnel through the Internet over an ISDN network. Router #1 Figure 1-5.
Page 39: Figure 1-6. Two Private Networks With Internet Access
In this illustration, all devices on both LANs (except for the Web server) are configured to obtain their IP addresses automatically from the built-in DHCP server in the BayStack 820 ISDN Router. Because these IP addresses are used only in the local LAN environment, these devices naturally form a private network with default network IP addresses of 192.168.168.xxx, and cannot be...

Page 42: Understanding Static Ip Addresses
The IP address server that manages the IP addresses is called a Dynamic Host Configuration Protocol (DHCP) server. By default, the BayStack 820 ISDN Router is set up to be your network’s DHCP server and it assigns IP addresses to the devices on your network as they need them.
Page 43: Understanding Gateways And Dns Servers
You can have only one IP address server on the network—either an existing DHCP server or the BayStack 820 ISDN Router. If you already have a DHCP server or do not want to use the router as a DHCP server, you must assign a static IP address to the router and then let all of your workstations know that the router is the gateway to remote networks.
Page 45: Installing The Router
This chapter describes the ports and LEDs on the BayStack 820 ISDN Router and provides instructions for connecting the router to your LAN or WAN. Before you install the router, make sure that you are familiar with the physical and environmental specifications of the BayStack 820 ISDN Router.

IP addresses. When you use the router’s built-in DHCP feature, the router automatically assigns IP addresses to the network workstations. You can change the private IP address of the router and, consequently, the pool of addresses from which the DHCP server assigns addresses.
Page 52: Connecting The Baystack 820 Isdn Router To The Network
Installation and Reference for the BayStack 820 ISDN Router Connecting the BayStack 820 ISDN Router to the Network Because the BayStack 820 ISDN Router is a DHCP server with its own private IP addressing scheme, you must use a standalone workstation to configure the BayStack 820 ISDN Router for the first time.

Restart the workstation. Restarting the workstation enables the router (as a DHCP server) to give the workstation an IP address from its private network, forming a mini-network between the router and the workstation.

Depending on how you configured the router’s voice ports, an inbound call can ring one or both voice ports. If you configured the router to ring both voice ports, the first extension to answer the phone receives the call. You can also connect answering machine or fax machine to the voice port and they operate in a similar manner.

Page 199: Connection Profile Commands
Connection Profile Commands Connection profile commands allow you to create and manipulate static profiles. Static profiles are created for connections communicating with a remote router, for example, Internet connections and remote LAN connections. Unlike user profiles (refer to dynamically, static profiles are maintained permanently and created at system initialization time from configuration information stored in flash memory.

Unsupported protocols: Bad addresses: Bad FCSs: Security Commands Security considerations in the BayStack 820 ISDN Router include several areas such as private IP addressing, callback for switched connectionconnection profile profiles, caller ID authentication for ISDN, and encryption. Security commands configure encryption.

Page 204: Disable Encryption
Installation and Reference for the BayStack 820 ISDN Router The encryption feature encrypts data before it is sent out to the WAN, and decrypts data when it is received from over the WAN. You can enable or disable encryption per connection profile. The encryption key is entered as hexadecimal digits (a hex digit is one of the following: fedcba0987654321).
