PSTN termination. 1

[Grenage]

Greetings,

One of my colleagues was considering connecting our ADSL lines to one of our spare patch panels, for easier management. While he was originally going to connect the line from the box on the wall, he believes it should be ok to take the line and terminate it directly, without the box in-between. While I suppose that's probably fine, I know that most PSTN boxes have a resistor and capacitor on the PCB. I have to assume they are there for a reason, so my questions are:

A) Does anyone know what they are there for (raw curiosity).
B) Is it ever an acceptable idea to directly terminate the PSTN line on a patch panel?

Thank you.

Some types of DSL termination boxes provide the voice/data split for you (a filter for voice is not required).

That box also serves as a logical and legal place for the telco to terminate their network. "This side is mine, that side is yours". You destroy the demarcation point by removing this box.

Even if "it doesn't hurt anything", you may get hassled or put off if a tech ever has to troubleshoot the circuit. Leave the box in place and extend to the patch panel from there.

Hi Tim,

Thank you for your reply. That makes good sense; I will have a word with my colleague and we will patch from the box on the wall.

Thank you again, and have a good weekend.

Russell.
