- Thanks to all who respoded to my inquiry on BONDING and T1 Multi-
- rate capability. Your information has been very helpful.
- As a follow on issue, I would be interested in obtaining more
- information on the BONDING protocols. I am currently supervising
- a development that provides both BRI and PRI support for devices
- attached to our line of communications processors. We have
- implemented a proprietary end-to-end protocol between our own
- devices that allows multiple B-channels to be brought into
- service to increase the end-to-end bandwidth. This capability is
- dynamic (channels are brought into and out of service as needed)
- and can span channels on combinations of BRI and PRI interfaces.
- This product was designed almost 2 years ago so the BONDING work
- was unknown to us at that time. I would like examine whether it
- makes sense for us to move to BONDING in future releases. Does
- anyone know where I might obtain the specs for the BONDING
- procedures?

- The big difference with ISDN on this point is that you are going
- to pay your service provider for each additional channel you
- bring on line. If you are running 2 B already (128K) and another
- 64K on line will cover your needs, why pay for another 128K?
-
- Also, always doubling gets a bit crazy when we get to future
- networking speeds. "Hello Mr. Salesman, I've got a 1 Gig pipe
- full now and I'm bringing another user on line next week. Better
- put me down for another Gig on Monday";-).
