Description Applications
ACP-300 Out-of-Band Network Switch & Call Router – 3 telephony devices share 1 phone line
The ACP-300 is an industrial grade Out-of-Band Network Switch, Dial-up Gateway, and telephone line sharing device….three solutions in one for remote network support.
Line sharing reduces costs significantly when you can share dedicated phone lines.
Key Benefits
  • The ACP-300 reduces or eliminates costly dedicated phone lines for fast R.O.I.
  • Hacker Shield Protection secures dial-up modems from unauthorized access
  • Control remote management port access for service vendors
  • Automatically directs calls to phone, fax, or modems
  • Streamlines polling and data acquisition processes
Call Routing
The Multi-Link ACP-300 automatically routes calls to phones, faxes, and dial-up modems, ensuring that the right resource is reached the first time. This consistent connectivity prevents time consuming dial-backs and streamlines polling and data acquisition processes such as SCADA, POS access, Substation/Revenue meter reading, Tank level monitoring, M2M communication, Submetering, and HVAC/Lighting control, etc. Multiple devices can share a single telephone line, eliminating costly phone lines and saving up to $50/month for each line eliminated. Businesses with multiple remote sites can realize a significant return on investment in 3 months or less.

As the image below indicates, the ACP is an ideal device for line-sharing at a gas station with a convenience store. If the cost of a single phone line is $50 per month, with 7 point of sale devices at a gas station, you could save up to $200 a month by reducing down to only 3 lines. That is an annual savings of $2400. In this case, the ACP-300 pays for itself in 2 months! (the ACP-500 is shown in the diagram)

Line sharing with ACP-300

Out of Band Access
The majority of Multi-Link’s phone/data line-sharing switches 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? Remote out-of-band access to management 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). Installed on an existing POTS line, the ACP provides an inexpensive, secure and controlled “out of band” path for accessing service ports to network equipment. Why pay a monthly cost for a line that you never want to use?

Dial-up Modem Gateway

Protecting access to IT systems and networks is becoming more critical in commercial and industrial applications.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. Service vendors that need to monitor their on-site equipment can now have remote access that is completely isolated from the IT network. This is most advantageous for service vendors working with Federal government agencies and businesses with strict IT security policies.

How does the ACP work?
The ACP is a call processor with an advanced feature set designed to route calls on an analog/simulated analog telephone line. Upon ring detection, the ACP will capture CID Data and answer the incoming call. After answering, the ACP immediately scans for a CNG (fax) tone or DTMF security access code (SAC). During this processing period, a Bell spec “ring-back” tone is provided to the calling party. If a security access code (SAC) is detected, the call is routed to the corresponding device port. If a CNG (fax) tone is detected, the call is routed to the designated fax port (Device 2 port).

In the absence of a CNG tone or security access code, the call is defaulted to the device 1 port. The original CID Data will be retransmitted after the first ring to any device port. All device ports have access to telephone line and outbound requests are performed in a standard fashion. Any device that tries to access the telephone line when the telephone line is in use will hear a busy signal. The emergency barge-in (EBI) feature allows the specified device port/ports to seize the telephone line and take priority in the event of a critical outbound call. This feature can be programmed ON/OFF (OFF by default) for devices 1 through 4 for the ACP-500 & ACP-900 units (1 through 3 for the ACP-300).

Regarding the Emergency Barge-In Feature of the ACP Series 2.0:

Please note that the Emergency Barge-In operation of the ACP Series 2.0 may not be optimal for achieving line seizure when used on the PRIMARY connection in applications involving emergency security equipment, e.g. fire, medical, police, first responder, or critical monitoring notification. Always validate approved connections with the appropriate local jurisdiction/ordinances and the Insurer of the business/property. If you choose to utilize the ACP Series 2.0 on a primary connection, it is highly recommended that all equipment involved is thoroughly tested and in compliance prior to final activation.
