G. CEPT-E1 Interface
The CEPT-E1 interface provides access to a maximum of two calls through Aero H+
voice services.
The CEPT-E1 interface connects to standard ITU or ARINC 746-compliant equipment.
Users can select the equipment through an ORT parameter.
H. Maintenance Port Interface
The HSD-440 Mark 2 Terminal is equipped with a maintenance port, located on the front
panel of the HSD-440 Mark 2 Terminal, with remote access also available through the
rear ARINC 600 connector. If the ports on both the front and back panels are connected,
the front-panel connection has priority and the back-panel connection does not function.
The maintenance port provides the physical connection to a password-protected MPU
that provides a system interface for users or service personnel who need to upgrade,
monitor, or troubleshoot the system.
The user connects to the maintenance port either through the maintenance 25-pin socket
D-Sub (DB25) connector on the front panel of the HSD-440 Mark 2 Terminal or through
a remote 9-pin socket D-Sub (DE9) connector via the ARINC 600 connector, as described
in
"Connection Requirements" on page 4-37.
A standard VT100 compatible terminal or computer (PC/laptop) running an emulator
program such as HyperTerminal©, ProComm (PCPLUS)©, or another serial
communication package provides the user interface to the HSD-440 Mark 2 Terminal
MPU. Configure the connection as follows:
Bits per second—19200
Data bits—8
Parity—none
Stop bits—1
Flow control—none
The HSD-440 Mark 2 Terminal supports two different end user access levels within the
maintenance port architecture: End User and Field Representative.
