anybody using 3600 WIC-2T at 4M or 8M ??

[micktyler]

A WIC-2T attached to one of the newer 3600 network modules (1FE1R2W in my case) will supposedly support 2 ports at 4M or one port at 8M as long as no other WIC is installed on the module. I am trying this by having 2 x 2M into an inverse mux and out from the Imux into the WIC-2T. The protocol only comes up if I have just one of the 2Ms connected.

The IMUX suppliers are sceptical about whether the WIC-2T will really support speeds in excess of 2M.

Has anybody else done this??

Thanks

Not sure about the WIC-2T card, but using an inversemuxer i've muxed 4x E1's on to a single port on a PA-4T card. The card seems to handle the 8M speed as long as none of the other ports are used on the PA-4T card.

OK, thanks, secondary question then.

In order to get the PA-4T port running at 8M was there anything special in the serial interface definition in the router ??

No,

The serial port was configured up just like any 2meg port. No special commands were used, the only difference was the phyical cable.
A RS-449 DTE cable was used between the serial port and inversemuxer, as a normal x.21 interface doesn't have any pins for clocking.

Sounds interesting. We are using X21 cable to the Inverse mux (RAD IMX-4E1) can you elaborate on the clocking requirement at all??

Just for info, if anybody else has problems with this, it DOES work! I am now running X21 at 4M thru WIC-2Ts in 1FE1R2Ws; standard X21 3 metre cables. (problem was with the config of the muxes)
