So 'Router's console port' --> to modem --> (From modem RJ45 to) POTS line.

Does this sound right?

If modem is used for OOB then you need to connect it to Aux port.<br />
I was thinking of something like TS which you connect to serial port.

This is what I have. It looks like its plugged into the console. &nbsp;Is that a serial connection on the modem? &nbsp;I'm not sure what that is, but let me know if you do.(right hand side)<a href="https://filedb.experts-exchange.com/incoming/2016/07_w29/1106306/Router-Console.png" target="_blank" title="Router-Console.png (68 KB)"><img alt="Router-Console.png" class="file-block lazyload" style="max-width: 655px;" data-src="https://filedb.experts-exchange.com/incoming/2016/07_w29/1106306/Router-Console.png" /></a>

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

Telecommunication occurs when the exchange of information between two or more entities (communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies.
