The majority of Multi-Link’s phone/data line-sharing devices are being installed for out-of-band dial-up modem access to communication and data networks.

When the network is down and normal in-band access is denied, how do you recover the network equipment? Out-of-band remote access to serial console ports provides an efficient back door method for recovery. This can be through the use of a backup dial-up modem via the Public Switched Telephone Network (PSTN).

Serial console ports are the most reliable and dependable form of communication for equipment management. That is why most high value networking devices have one. Whether it’s a router, switch, firewall, PBX, network storage device, etc, no matter what is happening with the device, the serial auxiliary or console port is always up and running. It is a trusted way to find out what is going on and the quickest way to recovery.

Polnet ACP Phone/Data Line Sharing Switch

The ACP saves money for IT departments by eliminating costly phone lines dedicated for out-of-band dial up access to remote network equipment. Fixed telecom costs are dramatically reduced and a 3 month R.O.I. is typical. In addition to savings, the ACP is engineered to provide an additional layer of security to connected devices. Vulnerable pathways to equipment via the PSTN are protected by programmable Security Access Codes up to seven characters. There are over 35 million combinations to choose from, effectively creating a telephony firewall for dial-up connections.

Furthermore, our Remote Power Control products, The Power Stone and the IP Power Stone 3000, are invaluable tools for rebooting unresponsive equipment in remote areas. The Power Stone is a phone call activated AC power controller used to reboot and power up/down remote equipment. The IP Power Stone 3000 provides the ability to reboot locked-up equipment via web browser.

Either of these remote reboot products makes a perfect complement to the Polnet ACP, providing inexpensive, secure control of remote network equipment.
