For example the Zyxel Omni TA128 has two serial ports, you connect each one to a serial port on your terminal server and use both channels at 64K (that's what I do, I have an Omni connected to a Cisco 2511, but am currently replacing this setup with a Livingston Portmaster 3). > 2.

The Omni (and I guess other TA's as well) can handle this automagically so it looks to your terminal server just like a fast (128K) modem. > 3.

But make sure to download firmware version 2.04 from ftp.zyxel.com, otherwise it will probably fail every day and you will have to turn it off :( -- Blaz Zupan, blaz@amis.net, http://www.amis.net/staff/blaz Medinet d.o.o., Linhartova 21, 2000 Maribor, Slovenia
