What is a Cisco 2600?

The Cisco 2600 series routers are used to tie networks together, usually at the Access level.

Each 2600 router has 1 or 2 Ethernet or Token Ring LAN interfaces, a Console and Aux port, and 2 WIC (WAN Interface Card) slots and an NM (Network Module) slot.

WIC cards can be used to give the router 1 or 2 Serial WAN connections each, or things like ADSL interfaces, T1 cards, etc.

NM modules can be used to give the router things like 2 extra WIC slots, 1 or 4 Ethernet ports, 4 slow serial WAN ports, 16 or 32 serial ports for controlling other routers, and many more.

2600 series routers are also obsolete and no longer sold.
