The R41 is a line powered responder in a small package designed to allow remote testing of communication lines. Just connect it to the line like a telephone and it is ready for measurements, no programming, no plug-packs, no batteries.

The R41 will automatically answer and terminate a call. Customer equipment is automatically reconnected to the line after completion of remote measurements.

When used in conjunction with the Level Meter LM41 it provides automatic performance analysis of a telephone line.

The R41 can be remotely controlled by DTMF tones. Audio feedback is provided so that the user can confidently operate the R41 by using a telephone.

Different operating modes allow testing for excessive noise levels, perform loss and slope measurements, impulse noise measurements, return loss and dropout measurements.

The following features are provided:

• Connects to the subscriber line just like a telephone
• Auto-answers a call, disconnects on busy tone
• Reconnects customer equipment after measurement
• No programming, no plug-pack, no batteries
• 600 W and TN12
• Remote noise measurements via telephone
