Modem Connection - Avaya 8800 Commissioning Manual

Commissioning fundamentals
(DTE) or data communication equipment (DCE). The default communication protocol settings
for the console port are listed below:
• 9600 baud
• 8 data bits
• 1 stop bit
• No parity
To use the console port, you need the following equipment:
• A terminal or teletypewriter (TTY)-compatible terminal, or a portable computer with a
serial port and terminal-emulation software.
• An Underwriters Laboratories (UL)-listed straight-through or null modem RS-232 cable
with a female DB-9 connector for the console port on the switch. The other end of the
cable must use a connector appropriate to the serial port on your computer or terminal.
Most computers or terminals use a male DB-25 connector. A null modem cable is shipped
with the chassis.
You must shield the cable connected to the console port to comply with emissions regulations
and requirements.

Modem connection

You can access the switch through a modem connection to the Avaya Ethernet Routing Switch
8800/8600, 8692 SF/CPU or 8895 SF/CPU modules. Avaya recommends that you use the
default settings for the modem port for most modem installations.
To set up modem access, you must use a DTE-to-DCE cable (straight or transmit cable) to
connect the Avaya Ethernet Routing Switch 8800/8600 to the modem. The following table
shows the DTE-to-DCE pin assignments.
