BCM 50 Analog Trunk Ports

[BCMTinkerer]

Does anyone have or remember the product bulletin that Nortel released regarding High Ring Voltage damaging analog trunk ports on the BCM 50, they issued a cable that had built in resistors that would be installed between the Amphenol and the Block.
I am trying to find the bulletin so i can find the part number.

thanks

I don't remember that but I have seen attenuaturs that are installed for that purpose. They came in several different configurations and had dip switches that reduced the line voltage. These also worked well for reducing echo when IP phones were used with analog lines. A web search should help you locate them.
