ASAI-Ethernet
13-4 Issue 7 May 1998
NOTE:
Lucent Technologies strongly recommends (both for security and
performance reasons) that the Ethernet connectivity between the MFB and
the set of hosts with which it will communicate be a separate LAN segment.
Customers who do not follow this recommendation are subject to an
unscrupulous person gaining access to the DEFINITY LAN Gateway
application in order to commit toll fraud and/or tamper with the real-time
aspects of CTI applications. (Toll fraud is the unauthorized use of your
telecommunications system by an unauthorized third party. Under
applicable law, the customer is responsible for paying for such unauthorized
usage.)
The serial cables attached to the TN2208 can be used for local and remote
administration as well as maintenance support.These are RS232 ports that allow
connectivity to a dumb terminal or to terminal emulation software on a PC. The
amphenol connector and the serial cable attached to the TN2170 are not currently
used.
The first serial cable attached to the TN2208 (labeled A in Figure 13-2) should be
connected to a 9600 baud (or better) modem that allows remote access by Lucent
Technologies services. This is a similar arrangement to the INADS port provided
on DEFINITY ECS. To enhance customer security, the modem should be turned
off except when access by Lucent Technologies is desired. The second serial
cable attached to the TN2208 (labeled B in Figure 13-2) can be used for local
administration.
Administrative Console Connectivity for MFB
The MFB is provided with two serial ports (labeled A and B in Figure 13-2) that
provide access to the administrative logins. The first port labeled “A” is dedicated
for remote access by Lucent Technologies Services. The second port labeled “B”
may be connected to a dedicated terminal, or to a shared terminal through an
“A-B” ECS. Additionally, once the LAN network administration is completed, the
administrative application may also be accessed by the use of “telnet” from a
remote system.
For customers who do not wish to have an additional, physical, permanent
console, it is recommended that the MFB be initially administered using a
temporary terminal, PC, or laptop. Once the LAN administration is completed,
telnet may be used from any host attached to the isolated segment (such as the
DEFINITY LAN Gateway client). This allows further (and ongoing) administrative
access without the need for a permanent console terminal. The overall
connectivity scheme is depicted in Figure 13-5.
