About the Console Download Function

You can use console download, which is a ROM monitor function, to download either a software image or a configuration file over the voice gateway console port. After download, the file is either saved to the mini-flash memory module or to main memory for execution (image files only).

Use the console download function when you do not have access to a TFTP server.

Note If you want to download a software image or a configuration file to the voice gateway over the console port, you must use the ROM monitor dnld command.

Note If you are using a PC to download a Cisco IOS image over the voice gateway console port at 115,200 bps, ensure that the PC serial port is using a 16550 universal asynchronous transmitter/receiver (UART). If the PC serial port is not using a 16550 UART, we recommend using a speed of 38,400 bps or less when downloading a Cisco IOS image over the console port.

Command Description

The syntax for the xmodem console download command is xmodem [-c-y]destination_file_name.

•-c—Optional. Performs the download using 16-bit cyclic redundancy check (CRC-16) error checking to validate packets. Default is 8-bit CRC.

•-y—Optional. Sets the voice gateway to perform the download using Ymodem protocol. The default is Xmodem protocol. The protocols differ as follows:

–Xmodem supports a 128-block transfer size. Ymodem supports a 1024-block transfer size.

VG202, VG204XM, VG204, VG202XM specifications

Cisco Systems has long been a leader in the realm of networking technology, providing innovative solutions for businesses of all sizes. Among its products, the Cisco VG202XM, VG204, VG204XM, and VG202 series stand out as vital components in voice gateway solutions for IP telephony applications.

The Cisco VG202XM and VG204 series are designed to facilitate the convergence of voice and data as businesses transition to VoIP (Voice over Internet Protocol). These voice gateways offer seamless integration with legacy telephony systems while enabling the deployment of advanced IP-based telephony features. They are particularly useful for organizations looking to preserve their existing investments in traditional telephony infrastructure while embracing modern communication technologies.

One of the main features of the VG202XM and VG204 series is their support for two-line interfaces, catering to varying deployment needs. The VG202 provides two FXS (Foreign Exchange Station) ports, which allow businesses to connect analog phones and fax machines directly. The VG204 enhances this capability by offering four FXS ports, accommodating larger user bases and providing more connections for local telephony equipment.

These gateways support an array of voice codecs and can handle up to 16 concurrent calls, ensuring high-quality voice communication in busy environments. Their integration with Cisco's Unified Communications Manager allows users to access a host of advanced telephony features such as call forwarding, voicemail, and conferencing.

On the technology front, the VG202XM and VG204 series support both SIP (Session Initiation Protocol) and H.323 protocols, making them versatile for varied network environments. They also offer advanced QoS (Quality of Service) capabilities, ensuring that voice traffic is prioritized over other types of data, which is essential in maintaining call clarity and reliability.

Additionally, the VG204XM variant adds built-in safety features, such as power over Ethernet (PoE), which eliminates the need for separate power supplies for connected devices. This not only streamlines deployment but also enhances the reliability of the voice system.

In terms of management, these devices are equipped with Cisco's user-friendly interface, which simplifies configuration and monitoring. They can be managed through various tools offered by Cisco, making it easier for IT departments to maintain and optimize their voice services.

Overall, the Cisco VG202XM, VG204, VG204XM, and VG202 series deliver robust, scalable, and reliable solutions for businesses aiming to leverage the benefits of voice gateways in their enterprise networks. These devices not only provide essential voice capabilities but also pave the way for future growth and integration in an increasingly digital world.
