Digital Phone Y-Adapter for BM12

[cmnstr]

I recently ordered the 1151C1 power supply for a phone with a BM12. My disti sent the new style power supply with a Y-Adapter and said this is the replacement because the 1151 is no longer being used. Has anyone used this new setup to be able to tell me if you can use a standard single pair cable from the DS port/wall jack to the single input of the adapter? I understand a CAT5 cable is required between the Y-Adapter and power supply and adapter to the phone. I am just concerned that if the customer has old wiring with RJ-11 jacks we will not be able to use this new setup without re-wiring everything.

Yes, I could have tested this at my location but I shipped equipment directly to customer site 3 hours away and was not aware they were changing what I ordered. I just want to make sure it works before I try to talk the customer through the setup.

Unless there is a different version of the document you sent that shows my configuration, the doc you sent simply shows the connection between an 1151D1/C1 to the phone. I am well aware of that setup. What I need to find out is if a standard telephone cable will work from the DS port to the NEW Y-Adapter that is being used with the NEW style PoE injector that is replacing the 1151 power supply.

If it helps clarify what I am trying to describe, we can no longer get the 1151C1 (700356447) power supply. The replacement is the SPP1 (700500725) with a Y-Adapter (700511777).

Now I'm with you =)

There should be a 700511777 PWR SUPPLY LOCAL 1151D1 48V that supposed to be used with 9508 and BM12B.

The Avaya Global PoE Y-Adapter for Digital Phone Button Modules seems to be for PoE so you should put the DS port in one of the Y ports and the power to the other an you'll get a powered DS port out on the other end.

Right but my question is about the cabling. Can the cable that goes from the wall into the single side of the adapter be a 1 pair cable:



|-----[SPPoE1]-----[Power lead]-----Power outlet
|-----Cat5--|
Wall ----1 pair cable or cat5-------[Adapter]--|
|-----Cat5--|
|-----[9508/B12]

Can the cable in the diagram above marked "single pair cable" be a regular RJ11 cable like you could use with the 9508 alone, or does it have to be Cat5? My customer's wall jacks are all RJ-11 so I don't want
to have to rewire the entire building for Cat5 to make a BM12 work. It sounds like you are saying the single pair will work but I just want to make sure.

It's an RJ45 connection, you are on your own to convert it to RJ11 with an adapter or simply replace the customer's jack to be an RJ45, which is what we have been doing.

The 9508 comes with a line cord that has an RJ-11 plug on one end and an TJ-45 plug on the other.

But, you know that you can plug an RJ-11 plug into an RJ-45 jack, right? It will go in and center itself into the socket, so you pull the RN-11 cable out of the back of the phone, plug it into the Data In port on the SPPoE brick, and use the supplied Cat-5 from the Data and Power Out port on the SPPoE brick back to the phone.

 

[qtelcom]

He's talking about the RJ45 male plug on the new Y-Adapter for digital phones with a button module, that new adapter will not fit into a Rj11 jack the customer has. You simply have to provide your own adapter, or replace the customer's Rj11 jack with RJ45 so the new avaya cheapo adapter will fit. We've been replacing the jacks in these cases, as I just can't stand having an adapter for an adapter, one more confusing thing for the customer if they unhook the whole mess.

I have not seen these "Y-adaptors" nor can I figure out what they would look like/where they would go, do you have a pic/official link?

I know the description I was giving may not have been the best but above is the diagram. What I was trying to figure out is since the connection on the Y-adapter that goes to the wall is RJ-45 does it still only use a single pair? We purchased a RJ-45 female to female adapter and plugged an RJ-11 into one side before going to the wall. The BM12 lights up fine. If they had kept the adapter simple and made all 3 ports female so you could use your own cable it would have made much more sense.

 

[janni78]

I would assume that the side with one port goes into the phone, and the POE and IPO DS port goes to the other end.

Doesn't it have any description on each port?

The side of the Y-adapter with one port goes to the digital station port of the IP Office. The side of the adapter with two ports are for 48v from the SPPoE and out to the phone. The adapter is marked.The diagram above shows this. Additionally, you only use the "data out" side of the SPPoE. It isn't the most efficient system and it causes extra wires and parts to be under the desk but at least it works.

 

[joe2938]

have you tried the 1 pair cable as that may be all it needs if it comes with that set up

 

[cmnstr]

That's the problem. The side of the adapter that goes to the IP Office is a molded cable so you can't use your own cable. This is why we went with the female to female RJ-45 adapter. If they had simply made that side of the connection a female connection so you could use your own cable the adapter wouldn't be an issue. This appears to be a simple case of too many engineers making this way too complicated.

 

[TouchToneTommy]

What I am still not understanding is the SPPoE 1A power brick. Does it NOT have a port labeled Data-In and this is why you are forced to use this Y-adapter?

This is the only image I've been able to find by searching on your part number 700511777

Is this what you are using?

 

[amriddle01]

What a pile of shit, would make more sense to just have the single port go to the phone and twin side be power and line in, makes no sense the way they have it

 

[critchey]

Looking at manual for the SPPoE 1A why is the y adapter needed? Looks like it would not be needed and manual makes no reference to that adapter. Are your sure your disti is not just plain wrong?

The SPPOE1A power rating is not the same as the 1151C1 so it will not work without the adapter. We definitely tried before calling to find out why the other part was sent. The Data In side of the SPPOE1A is not used for the BM12. It is my assumption that since the 1151C1 is discontinued then this same configuration will be required for 9600 series phones. Of course, 96x1 series phones already work with this power supply without the adapter. It would be nice to have an explanation as to why this was done but I wouldn't expect anything from Avaya. Unify is beginning to look more appealing. They are really pushing their product in the US so maybe it is time to take a closer look.

Maybe a dum question,

What tyoe of stations is the customer using. Your are talking about RJ11 cabling, so I assume a digital 95xx series..

But is the BM12 compatible to that? I think only 16xx series IP stations.

Isn't there a DBM12 available, jus as with the DBM32?
