DEFINITY LAN Gateway Multi- Function Board (MFB) and Multi-Application for DEFINITY Board (MAPD)
Issue 1 October 2003 215
DEFINITY LAN Gateway Multi- Function Board (MFB)
and Multi-Application for DEFINITY Board
(MAPD)
The DEFINITY LAN Gateway system is composed of a system assembly and a software
application. The system assembly is a DEFINITY Multi-Function Board (MFB) (TN2208)
and an Alarm Board (TN2170) inserted into a DEFINITY carrier. The DEFINITY LAN
Gateway system can also run using a Multi-Application for DEFINITY (MAPD) board. The
software application serves as an ISDN brouter (a combination of bridge and router) of
ASAI messages through a TCP "tunnel" via 10BASE-T Ethernet.
The DEFINITY LAN Gateway application may be administered using a terminal or terminal
emulator with the RS-232 console (serial) port, or using a terminal emulator that supports
TCP connectivity using the LAN port. Initial administration, or administration to configure
or diagnose LAN access on the MFB (or MAPD), should be performed using a serial port.
Ongoing administration may be performed using either the serial or LAN port.
Administration is supported using a full-screen menu-based application provided on the
MFB (or MAPD) and accessed via login and password. Administration screen categories
are as follows:
● Login/Password Administration — Allows administrators to add and delete user logins.
Also allows users to change their passwords.
● TCP/IP Administration — Provides access to all administrable network data: network
name and IP address of the DEFINITY LAN Gateway Multi-Function Board (or MAPD)
the user is accessing, all locally known hosts, and all network routing information.
● Brouter Administration — Provides access to a screen for viewing, adding, and deleting
brouter clients (see Chapter 7, "DEFINITY LAN Gateway Protocol" in the DEFINITY
Communications System CallVisor Protocol Reference 555-230-221).
● Maintenance — Provides access to backup and restore functions, loading of a new
system from tape, and the ability to view error and security logs.
● Port Status/Control — Provides access to port status and control data. Port status can
be viewed and client connections can be terminated.
