A rollover cable is typically used to connect from a DB9 serial port on your computer to the RJ45 console port on the router. An RJ45-RJ45 rollover can be used from Aux port to Console port or from the ports on a 2509-RJ/2511-RJ to a console port.

It's an Ethernet port used for network connections.
You Use a standard port on one device, and an unlink port on the other. after that connecte the standard Cat5 cable.

Uplink connections are typically used to connect the switch to a higher level switch, that is more powerful and closer to the backbone.On basic switch models, the regular ports are MDIX ports, meant to connect directly to a PC. The Uplink port is then an MDI port, which can connect (with a straight cable) to an MDIX port on a different switch. Often the highest numbered port (8, 16, or 24 for instance) has one MDIX port in the regular set and an MDI uplink next to it, but you can only use one of these two.You can use a crossover cable to connect MDIX to MDIX or MDI to MDI port.On more modern switches, ports are often MDI/MDIX autosensing and this reason for existence of uplink ports has passed (all Gigabit Ethernet has this, and many 100 Mbit Ethernet).In the mean time, however, switch models have come into being which have faster speed uplink ports. For instance, 10 Mbit switches with 1 or 2 100 Mbit ports to connect to the core network, or these days 100 Mbit switches with a few Gigabit ports.
No, you cannot. LAN ports are of type RJ45, when telephone port is RJ11. Basically it means that they have not only different size but also different number of wires.

No way. You must add a PCMCIA card with LAN connection.
its so simple...connect them to the RJ45 port of the router and see that the port blinks.this indicates that they r up and running
