MMI terminal connection scenarios
Introduction
There are several methods of connecting an MMI terminal to a
Meridian HomeOffice II Line Card for maintenance access. MMI terminal
connection may be made via:
■
dumb terminal (or PC COM port)
■
terminal server on a LAN
■
modem
Dumb terminal or PC COM port
In order to connect an HLC to a dumb terminal, such as a PC COM port, to
provide a man-machine interface (MMI) terminal for the system, attach the male
25-pin connector of the Meridian HomeOffice II Line Card Multi-I\O cable
(Plug 2) to the female 25-pin connector of the dumb terminal (or PC COM port).
This connection may require a 25-pin to 9-pin adapter.
If the HLC Multi-I/O cable is too short, attach Plug 2 of the HLC Multi-I/O
cable to the female 25-pin connector of the MMI extension cable (see page 47).
Then attach the male 25-pin connector of the MMI extension cable to the female
connector of the dumb terminal. This connection may also require a 25-pin to 9-
pin adapter.
The maximum distance between the HLC and the dumb terminal is
approximately 15 meters (50 feet). This allows approximately 0.5 meter (2 feet)
for the HLC Multi-I/O cable and up to approximately 14.5 meters (48 feet) for
the MMI extension cable.
Terminal server
To connect an HLC to a terminal server to provide a man-machine interface
(MMI) terminal to the system, attach the male 25-pin connector of the Meridian
HomeOffice II Line Card Multi-I\O cable (Plug 2) to a terminal server providing
access to the corporate LAN. This connection requires a customer-supplied
cable having the same pin-out as the MMI extension cable (see page 47), with a
female 25-pin connector on one end, and the proper interface for connecting to
the terminal server on the other end.
