Using AppleTalk
The native protocol for the Apple Macintosh is AppleTalk. AppleTalk is a transport
layer protocol, providing similar functionality to IP. This protocol is used for
connecting to native Apple file servers (known as AppleShare), other Macintoshes,
and to printers. A remote Macintosh user connects using Apple Remote Access
Protocol (ARAP), which provides similar functionality to PPP. Unlike PPP, ARAP
can transport only one protocol, namely AppleTalk.
Until recently, a Macintosh user that wished to use ARA would have to purchase
Apple Remote Access client. This is now bundled with PPP in a single client called
"Remote Access Client", included with the Mac OS. This client supports version 2.1
of ARA.
ARAP cannot be transported "as is" across a digital (ISDN) dial up connection but is
supported using V.120 rate adoption.
The Perle 833IS has built-in support for the AppleTalk networking protocol and no
special configuration is required. This allows an Apple Remote Access (ARA) client
running on a Macintosh to dial in to the 833IS and access the AppleTalk network.
AppleTalk is supported on both Ethernet and Token Ring connected Perle 833ISs.
Both ARA Version 1 and 2 clients are supported.
It is recommended that you use Version 2 ARA client software. If you are using a
Version 1 ARA client, you must change the modem initialization settings for the
Perle 833IS. Version 1 ARA software requires that the modem does not negotiate
compression or error correction. Other dial in clients and protocols will still work in
most cases, but performance for these clients could be degraded. If you require
modems that support Version 1 clients, it is recommended that these be placed in a
separate group.
If you are using a Version 2 ARA client, the modem settings as shipped by Apple
may not work. As with the Version 1 client you may disable error correction in the
server. However, you can retain your server settings by changing the modem
configurations used with the ARA software. See your modem vendor for these files.
Also, the Apple Remote Access Modem Toolkit Version 2.0 available from Apple
will permit you to create custom modem configurations.
The client name and password configured in the ARA client must match the name
and password within the 833IS. This name and password will be used solely to
access the 833IS, and do not correspond to names and passwords used to access any
other Macintosh.
