Chapter 3 Installing the Cisco VG224 Voice Gateway

Connecting Backup Power

Connecting to a Remote ASCII Terminal

To link a Cisco VG224 voice gateway to a remote ASCII terminal, such as a VT100, use the following procedure:

Step 1 Connect the remote ASCII terminal and modem.

Step 2 Set the terminal requirements:

9600 baud

8 data bits

1 stop bit no parity

no flow control.

Step 3 Key in the telephone number of the Cisco VG224 voice gateway external modem, or, if you are using a Hayes-compatible modem, enter ATDT and the number to be dialed.

Connecting Backup Power

A Cisco VG224 voice gateway can be installed with optional backup power. Backup power to a DC-powered chassis is provided by a 12-volt battery backup system; see the “Connecting a Backup Battery to a DC-Powered Cisco VG224” section for connection instructions. Backup power to an AC-powered chassis is provided by an uninterruptible power supply (UPS); see the “Connecting a UPS to an AC-Powered Cisco VG224” section for connection instructions.

Caution The Cisco VG224 chassis provides inputs for both AC and DC power. Design your installation to use only one type of power. Do not use AC and DC power at the same time. If you do, the unit stops operating, and you must reboot it with only a single power source.

The maximum power requirement for the Cisco VG224 voice gateway is 70 W.

Connecting a Backup Battery to a DC-Powered Cisco VG224

Connect a 12-volt backup battery to the DC input connector on your Cisco VG224 voice gateway. Before you install a backup battery, be sure to read the installation instructions for the backup battery equipment.

Figure 3-15shows a setup using an external backup battery.

Note Figure 3-15shows one possible setup; please review your backup battery documents before setting up your system.
