 PassageWay Telephony Services communicates with the DEFINITY
Enterprise Communications Server (ECS) through the DEFINITY ECS LAN
Gateway. Security Features are not provided in this system component.
For example, there is no encryption or password to prevent unauthorized
use of the Ethernet link into the PBX. The following are recommendations:
— Customers are warned that the DEFINITY ECS LAN Gateway link is
not intended for wide area networking. It is recommended that
customers not configure a LAN in such a way as to use the
DEFINITY ECS LAN Gateway link for local or wide area data
networking.
— Customers should provide a separate, secure link between their
PBXs and PassageWay Telephony Server(s). This presupposes a
separate network adapter and hub used only for the DEFINITY ECS
LAN Gateway interface.
In the Tserver, there should be no routing between the Network
Interface Card (NIC) used for the DEFINITY LAN Gateway and the
NIC used for client access. (This does not mean to imply, however,
that all Telephony Server clients have to be on the same LAN.)
For NetWare, if TCP/IP support is provided on a separate LAN, keep
this support isolated from the DEFINITY ECS LAN Gateway. For
Windows NT, configure the NT machine for a secure DEFINITY ECS
LAN Gateway connection. Refer to Chapter 2 in the PassageWay

Telephony Services for Windows NT

DEFINITY Enterprise
Communications Server Network Manager’s Guide.
 The PassageWay Telephony Server is only as secure as the underlying
system, either NetWare or Windows NT. Observe the security requirements
of your operating system.
In addition, for Windows NT, it is recommended that the following be used:
 Multiple level administration permissions to control which administrators
are allowed to pass on administration permission. See Chapter 3 in the
PassageWay Telephony Services for Windows NT Network Manager’s
Guide.
 Secure version of Windows NT with NTFS (NT File System). For additional
security information on Windows NT, consult a reference book such as
Inside Windows NT by Helen Custer or Windows NT Resource Guide by
Microsoft Press.
