T1 pt-to-pt

Hi,

We have a new T1 installed between 2 offices recently. I need to provision it for use. I know how to get it working with Routers(including CSU/DSU) on both sides of the T1 and then connect it to the main switch.

Is there any other way to make the T1 work without using routers?

Thanks,

There are all sorts of special types of equipment if your going to run IP down the circuit then hey go with routers much easier to deal with.  There are units from blackbox and adtran if your application is straight HDLC to DLC and such...

So specify what you are meaning.

Thanks

My COO seems to think that i can plug the T1 into an additional port on my firewall on both ends and make it work that way.

I want to confirm that before i tell him for sure that adding routers on both ends of the T1 is the best and easiest way to do it.

Thanks,
Dhaval.

What Is Threat Intelligence?

Threat intelligence is often discussed, but rarely understood. Starting with a precise definition, along with clear business goals, is essential.

the TZ-170 has only ethernet connections... A T1 is technically an RJ48s not a RJ45 the framing is esf not ethernet.  So no this is not something you can do.  You would at minimum need to have a bridge device that turns esf b8zs line code into IP packets.  so I would go with a router just to make things more manageable even if you just route.

Thanks

Your best bet is a router with a T1 connection built-in.  Otherwise, you could use a DSU/CSU to a serial port on a router.  For management, NAT translation, security, I would use a router with a T1 built-in like the Cisco 1700 with a WIC-1DSU-T1 on each end.   Easy to setup, manage, and secure.

You can get a used or refurbed router with T1 built-in for around $400 and brand new - multiple brands - for $700 - $800.

that is the minimum that you would want / need

There are also cisco 2500's all over the place on ebay and 1601 cisco's if you decide to go cisco look for a 1600 with a wic-1dsu-1t
