Product Overview
Reduce phone costs, improve connectivity, and secure your telecom equipment with Multi‐Link’s industrial grade phone line sharing device, the Polnet ACP.
The Polnet ACP enables businesses to communicate with remote telecom and network assets more affordably, efficiently, and securely.
The Polnet ACP (ACP) allows up to nine telephony devices to share a single telephone line, eliminating costly phone lines and saving up to $400/month per site. Businesses with multiple remote sites can realize a significant ROI in 3 months or less.
The ACP automatically routes calls to phone, fax, or dial‐up modems, ensuring that the right resource is reached the first time. This consistent connectivity prevents time consuming dial‐backs and helps to streamline polling and data acquisition processes.
In addition to cost savings and precise routing, 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.
How does the Polnet ACP work?
The ACP installs on an analog phone line and answers inbound calls at the first sign of ring voltage. After the ACP goes off‐hook, it immediately screens for fax and DTMF transfer codes. During this processing period, a “ring back” tone is issued to the calling party. Once a transfer command is received, the call is routed to the corresponding port. In the absence of fax/transfer codes, the call is defaulted to device port #1. Outbound calls are processed in the normal fashion with barge‐in protection. Priority call over‐ride can allow a device on port #1 to interrupt any transmission for critical outbound calls.
Highlights:
- 3 Ports
- Automatically answers the line and determines where the call should be routed by listening for programmed Security Access Codes (DTMF) or CNG tones
-Eliminates dedicated line costs
- Data disruption protection
- Remote diagnostic and programming
- Compatible with telephone systems
- Application flexibility
- Compatible with phone systems that do not generate DTMF tones during outbound calls
- Engineered with programmable security access codes for each device port
- Dual surge protection (defense against transient voltage carried over the phone line)
- Use for modems, data and credit card terminals, fax, modem, answering machines
- 2 Year manufacturer's warranty
- Multi-port polling feature will access more than one device during a single call
- In the absence of tone, the call will be routed to a phone or phone system (default port 1)
- Black
Features:
* AUTOMATIC FAX DETECTION - Pre‐programmed to auto route fax calls to fax or fax modem.
* DATA DISRUPTION PROTECTION - Prevents active calls from interruption by another device.
* PRIORITY CALL LINE SEIZURE - Call over‐ride for critical outbound transmissions.
* MANUAL TRANSFER CAPABILITY - Transfer a call to any device port by touch tones.
* PROGRAMMABLE SECURITY
* ACCESS CODES - User defined transfer codes, up to 7‐digits per port, restricts inbound access to equipment.
* BELL SPEC RING‐BACK TONES - The ACP transmits a “ring‐back” that sounds just like the phone company’s.
