Esat leased line with x.21/v.11 connection

lamaq

I've been asked to connect a PC up to an Esat leased line modem. The modem itself only has one connection coming out of it called x.21/v.11. It looks similar to a serial port only with slightly more pins.

I'm trying to get some sort of converter so it can be patched into an rj45 ethernet connection. Does anyone know who might sell these? Thanks.

X.21? Antique

X.21 will give you speeds roughly equivalent to 56k modems - usually lower rates. What I thought you would need is a router with an X.21 interface and an ethernet interface. Dunno about anything you can connect directly.
However, this may be a "proper" leased line (i.e. an E1 or something like that that gets decent speeds), as they can come with serial connections. Again I'd recommend a router with a serial interface.

Do you know the actual speed of the line?

lamaq

Not actually sure on the speed though I think it is only 56K speed. I was thinking a router would be the way to go but I don't know where you can get routers with that type of input?

Cisco certainly have routers with those interfaces.
Dunno who'd supply them in Ireland.

I think you will need a router of some type ( cisco etc)
X21 to rj45 converters are not readily available.
They also tend to give problems with clocking etc from the line.
cisco 2500 routers are usually used with the ESAT NTU that you have

I found a Cisco 1720 router with a serial cable that fits. Seems to be missing about 3 pins by design so I'm not sure if it is for an x.21 connection or not. Now I have to configure the router. :mad:

You'd normally use a basic cisco with an x21 port and an ethernet port to do the conversion.

Either that or relace the line with DSL, Wireless or Fiber
