The MAX 4000 is the "all over the world well known reliable workhorse" for small and medium internet providers.

Good for growing up to 4 E1(T1) nailed lines and up to 90 dial-in channels. It is extremely stable and reliable, and if you dont overstress the power supply and you keep it acceptable cool, it runs for years. The MAX 4000 has a 25 MHz Intel I960 CPU.

This is one of our MAX 4000, our dial in router with one modem card, running since end of 1996, the modem card was added 1999. We are running one E1 PRI WAN interface with up to 16 modems.

Here you see two open MAX 4000 chassis, one with its two power supplies and one with no power supplies.

You can easily see, its very tight together.
