Will the SBI-145 work on an Option 81 Nortel PBX?

No. This switch, now called the CS1000, uses proprietary signaling which is fully digital and its not supported by the SBI-145. The SBI-145 supports POTS (Touch tone and Pulse Dial) and Meridian Digital Centrex (EBS / P-Phone) which is used with the Nortel M5xxx series phones.

The CPI-101 is available in two models; a low impedance model and a high impedance model.  What is the difference between the two models?

The low impedance unit is designed to replace the telephone set on an MDC line. It is capable of receiving and transmitting all MDC codes, as well as receiving DTMF digits, decoding call progress tones, and generating dial tone. Our low impedance unit is ideal for telephony applications in a Centrex environment such as call management and distribution.

The high impedance unit is designed to coexist with an MDC set. It is intended for telephony applications where voice access to the line is required.  The high impedance has all of the features as the low impedance with the exception of tone reception and generation.

Does special software come with the CPI-101 unit, or do I have to buy it separately?

A: The CPI-101 does not come with line monitoring software. There are companies such as Conveyant Systems (http://www.conveyant.com, http://www.plantcml.com, http://www.kmltechnology.com ) which develop and distribute software that is compatible with the CPI-101.
