acceptable db on a trunk is NEG 4-6.5 db. Neg 4-5db can be a source of problems (whistle on 'S's and just plain squeal) when measuring C.O. '0' db at the customer switch with a loop tester. This is at the Demarc, NOT within the customers PBX

Thank
Lines can be a C.O. to demark for the plain that do not have go the far of PBX station.
Trunk can be a C.O. to the demark an then the PBX to station becauce the total db can not excede allow from c.o. the actual point is C.O. the to station.
I did not know value on db for trunk because I have not done it 20 year.
One instead I to figure out wye a particular set of trunk 34 a low in relationship with 135 all a the 1 PBX. The a is the what know a pot for the loaded a each pair where it not missing.
I with proper tester went in C.O. Frame an the length the 1 Load an the the second load the that up (voi-la). The was before loaded cable disp.

Intriguing. For a real challenge, try reading it out loud. Hopefully the question was satisfactorily answered.

WOW....GOD bless all of you that understood this. I guess I'm sorry I passed up crypto school in the Navy.
I think Stan is talking about a load coil on a span? Maybe not. I sure hope someone can figure this out.
