9.9 DTE Port Maintenance
9.9.1 DTE Port Overview
The DTE port on the back of IP Office control units is not normally used when configuring an IP Office system. However,
in extreme cases, the DTE port can be used to default the system's configuration or to erase it core software if
necessary.

WARNING
Due to the drastic nature of these actions, they should only be performed if absolutely necessary to return a system
back to working order. In both cases, you must make every effort to ensure that you have a backup copy of the
system configuration.
The DTE ports on IP Office expansion modules are not used for any maintenance or diagnostics except under instruction
from Avaya.
9.9.2 DTE Port Settings
These ports are found on the rear of all IP Office control units and external expansion modules. The DTE ports on
external expansion modules are not used.
The RS232 DTE ports on the control units can be used for system maintenance and connection of serial terminal
adaptors. On IP400 control units the port can also be used for connection of the IP Office serial port licence key dongle.
An asynchronous terminal program such as HyperTerminal is also required. Configure this for operation via a PC serial
port, as follows:
Bits per second 38,400 Parity None Flow Control None
Data bits 8 Stop Bits 1 Settings | Emulation TTY
DTE Cables
These cables are used for system maintenance and diagnostics under Avaya guidance. They can also be used for
connection of RS232 serial terminal adaptor equipment to the IP Office control unit.
The cable required depends on the IP Office control unit. This cable is a "Straight through DB9 female to DB9 male serial
cable".
