Page 25: Introduction
About the Router The Model RT338 router transports data from one local area network (LAN) to another LAN via a wide area network (WAN) connection. The router compares the network addresses of data packets sent through the LAN to entries in its address tables. If a match is found for a destination network, the router passes the packet to the path indicated by the entry in the routing table.
Page 26: Key Features
Standard basic rate ISDN (BRI) connection – ISDN, 2B+D, providing two 64 Kbps data channels and a 16 Kbps control channel – Two-wire U interface with internal NT-1 adapter on Model RT338-U router – Four-wire S/T interface on Model RT338-S router •...
Page 27: Isdn Support
Free technical support seven days a week, twenty-four hours a day ISDN Support The Model RT338 router is designed to take advantage of the ISDN technology for transmission of data over digital telephone networks. A BRI, which is the usual ISDN implementation, consists of two 64 Kbps B channels for data and one 16 Kbps D channel for control information.
Page 28: Tcp/Ip Support
1-5. IP Address Masquerading by Dynamic NAT+ The Model RT338 router lets several networked PCs share an Internet account using only a single IP address, which may be statically or dynamically assigned by your ISP. This process is also known as IP address masquerading and is an extension of Network Address Translation (NAT).
Page 29: Calling Line Identification
In many areas, you must specifically request that CLID be enabled by the telephone company for your ISDN line. In some regions, CLID may not be available. In the Model RT338 router, the CLID data is transmitted on the analog phone ports. Callback For security and cost accounting, the router uses Callback.
Page 30: What Is A Router
Routing Information Protocol (RIP). Using RIP, routers update one another periodically and check if there are changes to be added to the routing table. The Model RT338 router supports both the older RIP-1 and the newer RIP-2 Protocols. Among other improvements, RIP-2 supports subnet and Multicast Protocols.
Page 31: Table 1-1. Address Classes
Reference Guide for the Model RT338 ISDN Router There are five standard classes of IP addresses. The address classes determine the network and host sections of the address differently. Address classes allow for different numbers of hosts on a network. Each address type begins with a unique bit pattern, which is used by the TCP/IP software to identify the address class.
Page 32: Netmask
Reference Guide for the Model RT338 ISDN Router For each unique value of the network portion of the address, the base address of the range (host address of all zeros) is known as the network address and is not usually assigned to a host. The top address of the range (host address of all ones) is not assigned but is used as the broadcast address for sending a packet simultaneously to all hosts with the same network address.
Page 33: Figure 1-2. Example Of Subnetting A Class B Address
Reference Guide for the Model RT338 ISDN Router Subnet addressing lets you split one IP address into smaller physical networks or subnetworks. Some node numbers are used as subnet numbers. A Class B address provides 16 bits of node numbers, translating to 64,000 nodes. Most organizations do not use 64,000 nodes; free bits can be reassigned.
Page 34: Table 1-2. Netmask Notation Translation Table For One Octet
Reference Guide for the Model RT338 ISDN Router Table 1-2 lists the additional subnet mask bits in dotted-decimal notation. To use the table, write down the original class netmask and replace the 0 value octets with the dotted-decimal value of the additional subnet bits.
Page 35: Private Ip Addresses
IP addresses from the ISP. This approach is more costly than a single-address account, which is typically held by a user with a modem rather than a router. The Model RT338 router uses an address-sharing method called NAT. This method lets several networked PCs share an Internet account using only a single IP address, which may be statically/dynamically assigned by the ISP.
Page 36: Mac Addresses And Address Resolution Protocol
Reference Guide for the Model RT338 ISDN Router Figure 1-3 illustrates a single IP address operation. Private IP addresses assigned by user IP addresses assigned by ISP 192.168.0.2 192.168.0.3 192.168.0.1 172.21.15.105 Internet 192.168.0.4 192.168.0.5 7786EA Figure 1-3. Single IP Address Operation Using NAT This scheme offers the additional benefit of protection similar to that of a firewall.
Page 37: Domain Name System Server
Reference Guide for the Model RT338 ISDN Router If a device sends data to another station on the network and the destination MAC address is not yet recorded, ARP is used. An ARP request is broadcast onto the network. All stations on the network receive and read the request.
