88, 110, or BIX??

[Babybearjs]

so here we are finding 3 definitions for the same thing...... In the WE KSSM we find references to a #88 wiring system.   later it is known as the #110 connectors and system... and now the term "BIX" shows up.... so, which is it... and where did the changes come from?

They're not the same thing, exactly. In the UK we use Krone.

A 66 block (or "M Block") is used in older analog telephone systems.
A 110 block is often used in residential telephone and Cat 5 wire systems.
A Krone block is a proprietary European alternative.
A BIX block is a proprietary block developed originally by Nortel Networks.

I posted this as a history lesson of sorts... originally, the 110 wiring scheme was the 88 wiring scheme back in the 70's and 80's.... and now its known as the 110. where the term "BIX" comes from I don't know.... If you read the W.E. KSSM (key System Service Manual) you'll see what I'm talking about.... the evolution of the wiring system is interesting....I guess after the divesture things were renamed by the companies that took over the design.... (Leviton Mfg. , etc.,) but I still don't know who coined the term "BIX" does anyone know?

Nortel.

It is similar but different than 110. Different size and different tools.

I have never heard of 88 but it sounds like an "upgrade" from 66. Maybe 110 is an update from 88.

So, BIX is from Northern Telecom.... Interesting....
