Introduction

Overview of CallVisor ASAI Over the
DEFINITY LAN Gateway
bbbbbbbb
CallVisor ASAI over the DEFINITY LAN Gateway is a communications interface
that provides the functionality of the Adjunct/Switch Application Interface (ASAI)
using an Ethernet transport instead of a Basic Rate Interface (BRI) transport.  It
is supported by DEFINITY Communications System Generic 3V4, and by
Generic G3V2 and Generic 3V3 (except for Generic 3VS) after a field
maintenance release has been loaded.
The DEFINITY LAN Gateway system (ED-1E546-70) is composed of the system
assembly and a software application.  The system assembly is a Multi-Function
Board (TN2208) and an Alarm Board (TN2170) inserted into a DEFINITY carrier.
The software application serves as an ISDN brouter of ASAI messages through
a TCP ``tunnel via 10BaseT Ethernet.
The ASAI-Ethernet transport option can either replace or supplement BRI.  For
example, an ASAI-Ethernet link may replace an ASAI-BRI link if more throughput
is desired for the same client application.  Or, the ASAI-Ethernet transport option
may be used in addition to the ASAI-BRI transport option if a client application is
being added to the system and the customer does not want to disturb an existing
client application.
Because the DEFINITY LAN Gateway requires its own administrative information
(not found on DEFINITY), it is necessary to administer the system assembly
(TN2170 and TN2208) as well as the DEFINITY switch.  For the system
assembly to work with the LAN, the proper TCP/IP parameters must be set up,
and information about the clients who will use the ASAI-Ethernet service must be
administered on the system assembly.

							Introductionbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
CallVisor ASAI Over the DEFINITY LAN Gateway is provided with a default set
of administered parameters, but customers can also administer the LAN
parameters and client information to conform to their networks.
NOTE 1:
AT&T support services for the DEFINITY LAN Gateway system will not
troubleshoot a customer LAN.  If the customer LAN is experiencing
difficulties, customers should follow the escalation path supplied by their
LAN provider.
NOTE 2:
DEFINITY switch administration of ASAI does not change when using
CallVisor ASAI over the DEFINITY LAN Gateway.
Depending on the system setup desired, customers can configure and administer
the DEFINITY LAN Gateway system in several ways:
Using telnet over TCP/IP
Using a dumb terminal dedicated to the DEFINITY LAN Gateway circuit
pack
Using the RS-232 port of a PC or host attached to the DEFINITY LAN
Gateway circuit pack.
A menu-driven interface offers ease of administration, and help screens are
available if assistance is needed.  In addition, security features explained in this
chapter help guard against unauthorized access.
System Hardwarebbbbbbbbbbbbbbb
The application for the ASAI-Ethernet interface is supported by a system
assembly, a ``sandwich of the two boards mentioned previously, the TN2208
(Multi-Function Board) and the TN2170 (Alarm Board).  Figure 1-1 shows the
DEFINITY LAN Gateway system assembly.

Figure 1-1.  DEFINITY LAN Gateway System Assembly
NOTE:
The system assembly is also used to support DEFINITY AUDIXÒ.
However, the components are populated differently for DEFINITY LAN
Gateway and for DEFINITY AUDIX, so the hardware is not
interchangeable.  Be careful not to confuse a DEFINITY LAN Gateway
system assembly with a DEFINITY AUDIX system assembly when
installing or upgrading system software for either product.
Issue 1  January 1996

							Introductionbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
The DEFINITY LAN Gateway system assembly can be distinguished from
the DEFINITY AUDIX system assembly by the ``TN codes on the circuit
packs and by a DEFINITY LAN Gateway label.  The DEFINITY AUDIX
system assembly uses TN566 (not shipped on new systems), TN566B,
TN567, and TN2169 or TN2170.  The DEFINITY LAN Gateway system
assembly uses TN2170 and TN2208.
The TN2170 circuit pack supports a hard disk, Ethernet controller, and
removable media. It also supports a serial port, an additional analog modem port,
and remote maintenance hardware.
The TN2208 circuit pack supports a 32Mhz 486SLC Central Processing Unit
(CPU) with 16MB of fixed (non-socketed) memory.  It has 2 serial ports and a
user interface/Liquid Crystal Display (LCD) panel.  Naturally, it also has an
interface to DEFINITY call control and switching fabric.
System Softwarebbbbbbbbbbbbbbb
The software that provides the DEFINITY LAN Gateway application on the
system assembly comes preloaded on the system when it is shipped from the
factory. It is also supplied on removable media that can be reinstalled or used to
upgrade an existing system.
The function of the software is to act as a mapper (or brouter) for ASAI
messages.  It links an ISDN network (DEFINITY call control) to a TCP/IP
network (computer client) by moving ASAI messages back and forth from Q.921
synchronous data frames to TCP/IP Ethernet packets. It also associates
computer clients (by their TCP/IP network addresses) to physical ports on
DEFINITY that are administered as ASAI extensions.
This mapping provides a virtual point-to-point connection between a particular
computer client and an associated port on DEFINITY.  This arrangement
continues to support the ASAI ability to sense when a particular computer client
connection is lost and send an alarm.  It also provides a more secure
environment by fixing the addresses of the clients that may receive
DEFINITY LAN Gateway service.

Upgrading Your Existing Systembbbbbbbb
If you want to have CallVisor ASAI over the DEFINITY LAN Gateway in a
non-supported switch, you must upgrade it with a field maintenance release of
G3V4 software.  Contact the Technical Service Center at 1 800 248-1234 for
more information.  (You will be prompted for your Social Security Number and
4-digit PIN.)
If you attempt to upgrade from a pre-G3V4 switch, you must remove the
translations (assuming you had the TN2208 circuit pack aliased as a BRI circuit
pack in the pre-G3V4 switch).
!WARNING:
If you upgrade your system yourself, follow these precautions:
To prevent damage to the DEFINITY LAN Gateway system assembly,
make sure that you have connected the system assembly adapter cables to
the port connectors on the back of the switch (see Step 2 in Task 5: Install
the DEFINITY LAN Gateway System Assembly in Chapter 2) before you
insert the system assembly in the switch carrier.
You can install the system assembly in the switch when the switch is
powered on or off. When the assembly is inserted in the slots of the switch
carrier, it will automatically power up, run diagnostics, and boot. To avoid a
disk crash, never remove the assembly without first completing the
shutdown procedure to shut down the DEFINITY LAN Gateway system
(and allowing the disk to completely spin down).
For the same reason, do not cycle the power on the switch (for example,
during switch acceptance tests) once the system assembly is inserted
unless you have first shut down the DEFINITY LAN Gateway system. Refer
to the maintenance screens in Chapter 3 for the shutdown procedure.
Security Considerationsbbbbbbbb
Toll fraud is the unauthorized use of a companys telecommunications system by
an unauthorized third party.  DEFINITY LAN Gateway offers the following
security features to help prevent toll fraud and protect against unauthorized users
gaining access to the system and learning the content of calls:
Password protection Ð The system requires administrators to provide a
password before access is granted. Also, when the system is installed,
default passwords are changed to help guard against unauthorized
access.
Audit trail Ð DEFINITY LAN Gateway provides selective logging of an
audit trail of operations carried across the interface.  Users can view a set
of Security Logs to learn such information as failed login attempts,

unauthorized client access attempts, time of Multi-Function Board resets,
and commands executed from Administration/Maintenance screens.
This system does not support an encrypted/secured protocol; therefore, it is
possible for a criminal hacker to ``spoof the system by reverse engineering the
protocol and then ``impersonating a valid DEFINITY LAN Gateway client.
This is more likely to occur if the hacker has physical access to the Ethernet LAN
or to a system attached to the Ethernet LAN that supports the DEFINITY LAN
Gateway.  Customers are encouraged to help protect the system and reduce the
possibility of toll fraud occurring by attaching the system assembly and its clients
to an isolated, physically secure Ethernet (not connected to any other Ethernet).
