For example, the sample diagram does not indicate the physical type of connection between the PCs and the switch, but since a modern LAN is depicted, Ethernet may be assumed. If the same style of line was used in a WAN (wide area network) diagram, however, it may indicate a different type of connection.
The following diagram shows a scenario where an Ethernet-connected ADSL modem acts as a PPPoE-to-PPPoA protocol converter and the service provider offers a PPPoA service and does not understand PPPoE. There is no PPPoEoA in this protocol chain. This is an optimally protocol-efficient design for a separate ADSL modem connected to a router by ...
A CSU/DSU can have an external connection point or it can be integrated into a modular card installed in a router. A CSU/DSU is the equivalent of the modem for an entire LAN. The DCE, commonly a modem or CSU/DSU, is the device used to convert the user data from the DTE into a form acceptable to the WAN service provider transmission link. [1]
A modem and router work in tandem to deliver you an internet connection and then grant access to your various devices. Modem vs. router: The differences between the pieces of hardware that connect ...
Like SLIP, this is a full Internet connection over telephone lines via modem. It is more reliable than SLIP because it double checks to ensure Internet packets arrive intact. [4] It resends any damaged packets. PPP was designed somewhat after the original HDLC specifications. The people who had designed PPP included many additional features ...
However, a modem generally provides few other network functions. A USB modem plugs into a single PC and allows a connection of that single PC to a WAN. If properly configured, the PC can also function as the router for a home LAN. An internal modem can be installed on a single PC (e.g. on a PCI card), also allowing that single PC to connect to ...
The modem connects to a single computer or router, through an Ethernet port, USB port, or is installed in a computer PCI slot. The more common DSL router is a standalone device that combines the function of a DSL modem and a router , and can connect multiple computers through multiple Ethernet ports or an integral wireless access point .
One of them is the UPnP IGD client integrated with current Microsoft Windows and Xbox systems with certified IGDv2 routers. The compatibility issue still exist since the introduced of the IGDv1 client in Windows XP in 2001, and a IGDv2 router without a workaround that makes router port mapping impossible.
