COMDIAL OPX CONNECTION
- Thread starter DJSECI
- Start date
OPS = Off Premise Station (from PBX or Hybrid to other address location)
OPX = Off Premise Extension (CO line appearing at one or more other address locations)
They are NOT the same thing!
So what are you really trying to do?

Jim, OPS and OPX is the same thing.
From a telecom dictionary:
OPX is an acronym for Off Premise Extension. This is an extension telephone that terminates in a location distant from its parent PBX. OPX is generally used to provide an employee with access to his/her company's phone system while out of the office.
It is also sometimes referred to as a OPS, or Off Premise Station.
An OPX or OPS, is a conditioned pair usually for voice only. For data, the pair usually needs to be unconditioned. An alarm circuit is an unconditioned pair.
If you were to search for OPS:
Synonymous with off-premises extension (OPX). See OPX.

They are NOT and have NEVER been the same thing!!
When you place an order with the local telco, if you order an OPX, you will get an extended line from the CO switch, SAME NUMBER, to a different premise address(s) (just like a party line or telephone answering service, bridge lifters and all).
If you order an OPS you get a PBX STATION loop circuit from the PBX address to the off prem address.
My definitions are based on Pacific Bell's tariffs and 37 years in telephony!!!

You are right and the rest of the world including Newton's Telecom dictionary is wrong.
I was not questioning your knowledge or years in the industry as you seem to be very knowledgeable, I was just stating a fact.
You are correct that you would never order an OPX from a CLEC and ask for an OPS. But that does not mean it is not the same thing. Most PBX manufacturers will refer to their analog OPX station cards as OPX or OPS and their part nunbers will include OPX in their sequence.

Jim,
You're right and you're wrong. Mechanically, an OPX and OPS are identical. Sure, you don't order an OPX when you want an OPS, but the hardware used to transport them is the same.
So, in Comdial parlance, an OPX card can be used for both on-premise and off-premise single line extensions. It that case, the only difference is protection and voltage.

Unfortunately, too many terms and acronyms are misused and bandied about in this industry. That causes a lot of confusion and things being misapplied and misunderstood, both from people and companies. If people would take the time to look or research a little, we would all be better off, and better informed.
(My pet one is the misuse of "RJ.." But we won't go there on this thread) lol
I guess Avaya did it right, in the Legend manuals, they refer to the module as a 008OPT. (Off Premise Telephone) lol
