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.)
Two of the serial cables attached to the TN801 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
serial cable (labeled DCIU in Figure 13-4) is not currently used.
The first serial cable attached to the TN801 (labeled Maint/Port A in Figure 13-4)
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 TN801 (labeled Admin/Port B in Figure 13-4) can be
used for local administration.
Administrative Console Connectivity for MAPD
The MAPD is provided with two serial ports (labeled Maint/Port A and Admin Port
B in MAPD Figure 13-4) that provide access to the administrative logins. The first
port labeled “Maint/Port A” is dedicated for remote access by Lucent Technologies
Services. The second port labeled “Admin/Port 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 MAPD 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
MAPD 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.
