Viking DLE-200B Two-Way Line Simulator

This is a powerful and deceptively simple gadget. If you connect an old-fashioned analog phone to each of its two ports, picking up one phone will cause the other to ring. If someone answers the other phone, you can talk back and forth.I used this to set up an intercom between the house and my workshop using the "second line" wires on the existing analog POTS wiring. This only took a few minutes to set up and works flawlessly.

I used this to make a telephone system between the helm and salon on a boat. Works perfectly. If either phone is picked up, then the other phone rings. The voice comes over loud and clear.

Old rotary phone compatible. Works great.

This is the coolest device. Arrived new, well packed and works right out of the box. No programming required. Just move some dip switches to change basic features like how soon the ringing starts. No dialing. Plug in two phones, lift one (off-hook) and the other rings. Very compact design.

Works Great. Easy Install.

We live in an old house with phone jacks. I plugged in a line to the phone jack and a line to a phone. Other phones plugged into phone jacks around the house also ring. So cool!

We use this to test between 2 fax machines when setting up copy machines, & it saves us the expense of a second dedicated phone line. We had a problem with the unit almost a year after buying it (looked like it had fallen off of the bench or been dropped, but cant get any of my techs to admit it) and sent it in for warranty repair. It was repaired & returned to us free of charge within a week.Would buy another one in a heartbeat!

This little device is perfect for testing incoming calls on a FreePBX system. I'm building out a new phone system for a local school and needed to test the incoming analog lines. The DLE-200B was easy to use and worked perfectly. Just plug it in and pick up the phone, it couldn't be easier.
