Max distance on a BCM 4.0

[stevomorrison]

Does anyone know the maximum distance a digital set can be away from the BCM 400. Is there a difference with the analog sets.

1000 ft.

You can put a SAP in parrallel and get maybe 500 more.

Is it 1000 ft without a power supply?

 

[Deweyhumbolt]

Affirmative.

Thank you ed, I archived this. Honestly, I haven't got a TDM set to work past 2000ft., with a SAP.

Deweyhumbolt, keep in mind that the distance is dependant upon the loop resistance. 2600 feet is the expected distance for a TDM set, only if the loop resistance is 64 ohms. The distances/loops in my chart are based on 24AWG (0.5 mm) wire. I should have included this assumption with my chart. I hope this clears it up.
