New Features
• Valid values for
addr-range
are two Internet addresses separated by a
hyphen. The first Internet address in the address range represents the
lowest acceptable address. The second Internet address in the address
range represents the highest acceptable address.
• There is a new command to specify whether or not PPP negotiation
packets will be logged in the verbose accounting log, and the format in
which they will be logged. This should only be used as a diagnostic tool in
the event of interoperability problems.

CCL Enhancements
Command Control Language (CCL) scripts are files that contain commands
that initialize a modem, configure communication between the modem and the
device to which it is connected, and manage call-answering and call-hang-up
activities.
CCL scripts were originally designed to be used with AppleTalk Remote
Access Protocol (ARAP). While CCL scripts are required for ARAP
connections, beginning with V5.3 they can also be used to initialize the port
and modem for other types of connections (PPP, SLIP, interactive, etc.). There
are some benefits to using CCL scripts even at ports where ARAP connections
will not be used. First, you can use CCL scripts as an easy way of programming
the modems. Second, you can think of a CCL as an alternate method of
“autobauding” the serial port connected to the modem, since the CCL will
determine the appropriate port speed and set it accordingly.
The Model 3395A server software kit provides CCL scripts for selected
modem types that have been tested with Model 3395A servers. Model 3395A
servers also supply CCL scripts that have been modified to take advantage of
the following features:
• Kerberos and SecurID authentication features when making ARAP
connections. (These CCL scripts were first made available in V5.2.)
• V.42 LAPM error correction or V.42bis data compression for
“non-ARAP” connections (PPP, SLIP, interactive, etc.) at ports that use
Automatic Protocol Detection (APD) to support both ARAP and
non-ARAP connections. (These CCL scripts are new for V5.3.)
AppleTalk Remote Access (Version 1) required that modem connections be
made without using any error correction or data compression methods. The
modified CCL scripts allows the server to accept ARAP connections without
using error correction and data compression, while non-ARAP connections can
negotiate these options.
You do not need to use a CCL script with these modifications if APD is not
enabled at the port, or if ARAP is not among the connection types (protocols)
that will be accepted at a port where APD is enabled.
