Command Communications ComSwitch 7500 - 4 Port Auto Voice/Data Switching Device (Discontinued)

• Automatic line sharing - Lets up to 4 devices - usually a telephone, answering machine, fax and modem - share a single phone line
• Distinctive Ring mode for simple line sharing - When you add a second or third phone number to your single line, the CS 7500 works smoothly with Distinctive Ring service offered by most local phone companies (different companies have various names for this service; check with your phone company for details) - able to recognize specific ring patterns assigned to your different phone numbers and route calls to the right device
• Choose "Automatic" or "Semi-Automatic" mode - Immediately answers every call in the "Automatic" mode - if you prefer to have all your extension phones ring normally, the "Semi-Automatic" Mode is also selectable
• Compatible with phone company Voice Mail and Caller ID - works with Voice Messaging from the phone company (requires Distinctive Ring service activation) - also compatible with Caller ID service (requires service activation)
• Remote message notification - Never miss another important message while you're away - every time you receive a voice message, fax document or data transmission, ComSwitch 7500 will automatically send a special tone message to any desired telephone number - local or long distance (not compatible with tone pagers)
• Two line compatibility - Works equally well with one or two telephone lines - even more important, the system is compatible with two-line telephones, something you seldom find in other systems
• Save money on a scanner - Convert your fax machine into a full page, multi-document scanning system by using built in ComScan feature - just the touch of a button and your fax machine sends images directly into the fax/modem in your PC - electronic images are a snap - reverse the process and your fax machine acts like a printer
• Monitoring - Stays on the line during every call, listening for tone commands you send from the keypad of a telephone - talk for a few minutes, push three keys, and transfer the call to your fax machine to receive a document

Manufacturer recommends a minimum of 2 DSL filters be installed ahead of the ComSwitch when subscribed to DSL service.
