Figure 1. Cisco router with serial interface, configured as PPP Half Bridge.

For example, the customer site is assigned the addresses 192.168.1.0/ 24 through 192.168.1.1/24. The address 192.168.1.1/24 is also the default gateway for the remote network. The above settings remove any routing/forwarding intelligence from the CPE. The associated Cisco con- figuration will set serial interface (s0) to accommodate half bridging for the above example.

Authentication is optional under PPP. In a point-to-point leased-line link, incoming customer facilities are usually fixed in nature, therefore authen- tication is generally not required. If the foreign device requires authenti- cation via PAP or CHAP, the PPP software will respond with default Peer-ID consisting of the units Ethernet MAC address and a password which consists of the unit’s Ethernet MAC address.

Some networking systems do not define network numbers in packets sent out over a network. If a packet does not have a specific destination network number, a router will assume that the packet is set up for the local segment and will not forward it to any other sub-network. However, in cases where two devices need to communicate over the wide-area, bridging can be used to transport non-routable protocols.

Figure 2 illustrates transparent bridging between two routers over a serial interface (s0). Bridging will occur between the two Ethernet Inter- faces on Router A (e0 and e1) and the two Ethernet Interfaces on Router B (e0 and e1).

On the other hand, the Patton 2130 model focuses on VoIP (Voice over Internet Protocol) connectivity, facilitating the transition from traditional telephony systems to IP-based communication. This model supports multiple VoIP standards, including SIP (Session Initiation Protocol) and H.323, making it compatible with a wide range of VoIP applications and services. The 2130 also features high-definition voice codecs, which improve call quality, and a built-in echo cancellation function that minimizes audio distortion during calls.

Both models leverage Patton’s innovative SmartNode technology, which streamlines management and monitoring through web-based interfaces. This capability enables users to configure settings, monitor performance, and diagnose issues remotely, enhancing the overall efficiency of network operation. They are equipped with various interfaces including Ethernet ports, serial ports, and options for multi-port configurations, catering to different deployment scenarios.

Moreover, the rugged design of the 2124 and 2130 models ensures durability in demanding environments. They are built to withstand a range of temperatures and can be mounted in various configurations, adding flexibility to installation options. Power over Ethernet (PoE) support in these models simplifies installation by eliminating the need for separate power supplies.

In summary, the Patton Electronics 2124 and 2130 represent a blend of reliability, versatility, and cutting-edge technology, making them ideal choices for organizations embracing modern networking needs. Whether integrating legacy systems or enhancing VoIP capabilities, these devices are poised to meet the diverse requirements of today’s digital landscape.
