- |There are two solutions I know of to link a PC at home with work over ISDN:

- |1) Buy a pair of Combinet ISDN Ethernet bridges (~2K ea) and put small
- | ethernet at home bridged to an ethernet segment at work. This works
-
- |2) HP, as one example, makes an AT-bus ISDN card for the PC. It provides
- | 2B access to ISDN and requires a similar setup at the work end: i.e.,
- | ISDN card in a PC with SCO Unix providing a routing function between
- | the ISDN card and an ethernet segment.
-
- Is it absolutely necessary to have two of the same hardware? I have
- one lab full of machine dependent (i.e., SBus, NuBus...) (no PCs) ISDN
- cards/boxes and am hoping to find an IDSN/ethernet bridge/router for a
- remote (PC based) lab that will allow me to talk TCP/IP to at least
- one of them.
-
- Is there any easy way to tell if two ISDN devices are compatible?
- That is, if I will be able to use TCP/IP?
-
- A bit aside, how do you control the bridge? I assume that you need
- some sort of software running somewhere that sends
- control/configuration data over the ethernet. True? If so, is this
- software typically available for DOS boxes?
-
- Is it easy to configure them (the bridges) to multiplex two 64K
- channels? To drop the line during idle time? Is this transparent to
- the ethernet?
-
- Thanks for your help.
