Can a 25-pin Ethernet cable be used with a terminal server?
If so, remember that the 25-pin interface is a DCE, and you must use the RJ-45-to-25 pin adapter marked "modem" to reverse the roll and complete the connection. The major benefit of a terminal server is that it allows you a single point from which to access the console ports of many devices.

What is Cisco AS2511?
Designed to deliver smart computing solutions, the Cisco AS2511-RJ is a simple and powerful 17-Port wired router that enables users to connect asynchronous devices such as dumb terminals, router consoles, slot machines, and ISDN terminal adapters (TAs) to a routed network . Additionally this Cisco router also gives users integrated synchronous serial ports to backhaul routed traffic through high-speed T1/E1 lines. This Cisco AS2511-RJ allows you to share high speed internet connection among computers via an Ethernet cable. The Cisco AS2511-RJ runs on Cisco IOS software, letting you access high speed internet continuously, without interruption. The 17-Port wired router is designed in a manner such that the Cisco router can be easily mounted in a rack or wall.

Cisco AS2511-RJ 2511 Series 16-Port Async Universal Access Terminal Server Server / Router units which are shipped internationally have a mandatory 4-10 business day security holding period between payment being received and shipment processing. This security policy is to allow funds to fully clear our bank account. International transport costs can be charged directly to your FedEx or UPS account number. We cannot ship internationally using your TNT account number; however you can coordinate with TNT to have them pick up the shipment from our location.
What cable is used for Cisco 2509?
The Cisco 2509 - 2512 series routers use a 68-pin connector and breakout cable. This cableprovides eight RJ-45 rolled cable async ports on each 68-pin connector. (See CAB-OCTAL-ASYNC Cable Pinouts.) You can connect each RJ-45 rolled cable async port to the console port ofa device. The 2511 router allows for a maximum of 16 devices to be remotely accessible. Inaddition, the NM-16A or NM-32A high-density async network modules are available for the Cisco2600 and 3600 series routers to provide the same function. (See Understanding 16- and 32-Port
What is a terminal server?

What is terminal service?
Terminal services provide terminal-to-host connectivity with virtual terminal protocols including Telnet, local-area transport (LAT), TN3270, and rlogin. Terminal services can be used to connect to a modem in a modem pool for outbound connectivity.
What is an access server?

How to make a terminal server accessible?
In order to make the terminal server accessible, assign a registered public Internet address, and locate the server outside the firewall. When you do so, firewall issues do not interrupt your connection. You can always maintain connectivity to the terminal server and access the connected devices.
How to connect to terminal server through the internet?
Use the ip default gateway statement, and point to the the next hop router on the Internet. This command enables you to have connectivity to the terminal server through the Internet even if routing is not enabled. For example, the terminal server is in ROM monitor (ROMMON) mode as a result of a bad reboot after a power outage.
What is the port number of a TCP connection?
tcp-port-number : This field represents the TCP port number to which you want to connect when you use the defined host name along with an EXEC connect or telnet command. In our example configuration, we use a reverse Telnet so the port number must be 2000+line number.
What cable is used for Cisco 2509?
The Cisco 2509 - 2512 series routers use a 68-pin connector and breakout cable. This cable provides eight RJ-45 rolled cable async ports on each 68-pin connector. (See CAB-OCTAL-ASYNC Cable Pinouts .) You can connect each RJ-45 rolled cable async port to the console port of a device. The 2511 router allows for a maximum of 16 devices to be remotely accessible. In addition, the NM-16A or NM-32A high-density async network modules are available for the Cisco 2600 and 3600 series routers to provide the same function. (See Understanding 16- and 32-Port Async Network Modules .) For more information on cabling refer to the Serial Cable Connection Guide and the Cabling Guide for Console and AUX Ports.
What is a terminal server?
A terminal server is a router with multiple, low speed, asynchronous ports that are connected to other serial devices, for example, modems or console ports on routers or switches.
How to exit telnet session?
Use the escape sequence Ctrl-Shift-6 then x to exit the current Telnet session.
What is a 68 pin connector?
Note: The async ports from the 68-pin connector are data terminal equipment (DTE) devices. DTE to DTE devices require a rolled (null modem) cable and DTE to data circuit-terminating equipment (DCE) devices require a straight-through cable. The CAB-OCTAL-ASYNC cable is rolled. Therefore, you can connect each cable directly to the console ports of devices with RJ-45 interfaces. However, if the console port of the device to which you connect is a 25-pin interface (DCE), you must use the RJ-45 to 25-pin adapter marked "Modem" (to reverse the "roll") in order to complete the connection.
What type of cable does a Cisco 2511 router use?
The Cisco 2511 series router uses a 68-pin connector and breakout cable (see Figure 4-13 ).
How many asynchronous lines are there in Cisco 2511?
In the lab, you are really concerned with only Lines 1 to 7 (2001 to 2007) because they are the only asynchronous lines that have routers connected to them. However, because a Cisco 2511 has two asynchronous interfaces, 16 lines total are available (8 per asynchronous interface) for configuration.
Why is reverse telnet successful?
Notice in Example 4-25 that the reverse Telnet session is successful because the connection shows Open and you are taken to the router prompt of each respective device. R1 is the only router with a configured host name because it is the only router that you have configured with a host name so far. Thus, the remaining routers take you to the Router> prompt.
Why use a terminal server?
The major benefit of a terminal server is that it allows you a single point from which to access the console ports of many devices. This is helpful initially in the lab because the lab routers will not have any configuration settings such as IP addresses or Telnet parameters. Without the terminal server, you would have the tedious process of manually switching between each router's console port to gain access. A second benefit is that a terminal server can provide fault tolerance in case the routers become inaccessible because of a network failure. This is because you can configure a modem on the auxiliary or asynchronous port of the terminal server, allowing dialup connectivity to the terminal server and thus to each router that the terminal server is connected to.
What is reverse telnet?
Reverse Telnet means that the Telnet session is initiated out of the line (like an asynchronous line) instead of accepting a connection into the line.
What is a CAB-OCTAL-ASYNC cable?
This cable is referred to as a CAB-OCTAL-ASYNC cable or just OCTAL cable. It provides eight RJ-45 rolled cable asynchronous (async) ports on each 68-pin connector. The 68-pin connector is attached to Interface Async 1 of the terminal server. Each RJ-45 rolled cable is connected to the console port of each router in the lab. For configuration purposes, each rolled cable is referred to as an asynchronous line in the configuration. Each line is numbered beginning with 2001 to 2008. So, R1 is attached to async 2001, R2 is connected to 2002, and so on up to 2007, which is connected to the Catalyst 1900 switch, leaving 2008 unused. See Figure 4-14 for an example.
How does reverse telnet work?
For reverse Telnet to work, the interface that is used must be up and the line protocol must be up. Because of this, using a loopback interface is advantageous because it never goes down, as opposed to an Ethernet interface, which might go down and prevent reverse Telnet from working.
