We need to bridge some appletalk zones (via modems) and I heard that a box
put out by Shiva called a telebridge will do just that. Now comes the
questions:
1) How does one initially setup the connection from one zone to another
remote zone? Can anyone on the appletalk network indicate what number
to dial?
2) Can multiple modems be connected to a TeleBridge to provide more paths
into a single zone? Or are multiple Telebridges needed?
3) Not that it should matter, but has anyone had any problems with the
Telebridge and System 7?
4) What other information can any of you provide in regards to bridging
appletalk zones via modems? Other products available other than
Shiva's Telebridge?
Thank you,

David We are using several Shiva telebridges at the University of Sydney to bridge appletalk using leased lines. In answer to your questions, >1) How does one initially setup the connection from one zone to another > remote zone? Can anyone on the appletalk network indicate what number > to dial? There is a network manager application which is used to configure the TeleBridge, by controlling who has this you can control who has the ability to configure the TeleBridge, you can also protect the configuration with a password. To get the TeleBridge to dial out you need an init/cdev by restricting this you can control who can connect to remote sites. Once the connection is made anybody who is on your network can see and use the network on the other side. >2) Can multiple modems be connected to a TeleBridge to provide more paths > into a single zone? Or are multiple Telebridges needed? No you can only have one TeleBridge connection between two networks using one modem at each end. If you want more bandwidth you should get a faster modem. BTW: Do not use TrailBlazers, the line turn around time is too long for the sort of traffic that appletalk generates. >3) Not that it should matter, but has anyone had any problems with the > Telebridge and System 7?

Other products available other than > Shiva's Telebridge? ***FLAME ON*** There is a bug in the firmware of the TeleBridge. The TeleBridge does not pass tickle packets from file servers to clients or vice-versa. This does not cause a problem on appleshare servers or clients as the packets are ignored but CAP/aufs follows the protocol specification faithfully and times the connection out after two minutes. The local distributor here in Australia has been very helpful but Shiva tech support is pathetic. Convincing them that there was a problem was a trial involving faxing pages of inside appletalk across the pacific. They then acnowledged that there was a problem and said that they would send out some new ROM's and software. That was at the begining of April, I am still waiting, presumably the turkeys sent it by sea mail. Apart from this they work well. ***FLAME OFF*** There are also boxes that have the modem built in such as the Shiva NetModem, this is cheaper than buying a TeleBridge and modem combination but the modem speeds are not all that high (9600 bps) while the telebridge can go to 57,600 bps. Solana also make a similar product called the R-Server (?) regards Gilbert Gilbert Taylor-Wood gtw@extro.ucc.su.OZ.AU Faculty of Arts Programmer The University of Sydney NSW 2006 Tel: +61 2 692 4713 AUSTRALIA Fax: +61 2 692 2045
