Capt,
Regarding your original post, is it your intent to utilize both 8410Ds simotaniously? If so, I don't think a splitter would work. The ISDN BRI circuit which supports the 8410D cannot be physically split for "simotanious" use by 2 separate 8410D instruments. If both 8410Ds were configured identically, a splitter would "may" work, but only for one 8410D at a time.

You're correct in that you can split individual line [analog] dialtone to multiple instruments.

I recomend the below option:

1. Request the government to convert your current BRI circuit to an Individual [analog/non-BRI] Line, then install a separate instrument [sharing the same individual line as yours] for the lady in your office to use for outbound calls.

I've also attached a link to some further information regarding your 8410D:

I wish I could help you more with this.

There will never be simultaneous usage.

Our office is authorized for only one phone, so this is something I will have to handle COMPLETELY on my own, without access to anything other than what is in the office itself.

Our desks are in diagonal corners and it is a pain for her to come over to make calls. I was thinking of a "three-way" switch on each desk where either person could seize control of the phone line.

Now I'm confused. Does this office have a PBX in it? Or is this phone connected via a BRI line?
Either way, like Liquid said, it won't work.
Connecting two digital phones to one port WILL NOT work. End of story.
Hooking some kind of switch...? Sounds rather elaborate. It would have to completely disengage one of the one phones from the PBX. If a PBX "sees" two phones it will not work. I don't know of any digital switch that will allow two phones on the same port. Certainly not with separate extensions

Connecting remotely? Done that a long time ago with a BRI line so I don't recall the particulars, but again I doubt it will work.

An 8410D does not have an analog port on it. The 8411D does. But you would still need it to be programmed at the PBX to accomadate it.

You could use a switch and have two phones on the cicuit if you only have one phone active at any time. You would have to
SPID each phone while active on the circuit and have only one phone active at any time. If you were to try to make both phones active at the same time, one phone would not be able to see the cicuit. Also it is important to always keep one phone active as clec will turn off the cicuit if there is no phone at your end.

I may have been mistaken but I assuned you were using ISDN phones.

I've never seen this done, but that doesn't mean that this isn't possible..

I must recomend that you check with your local DOIM (explain your situation to them), before proceeding any further. The DOIM may already have a possible fix, based on someone else whom was in the same situation, and plus it eliminates alot of headaches if this doesn't work, and you accidentally lose your communication with the ISDN Network.

Regardless, before purchasing the additional instrument, you should see if you could temporarily borrow another 8410D, to test and confirm this type of install. *Remember: The configurations of both 8410Ds (all the way down to which lines are assigned on each call appearance button) much match identically. If not, the BRI circuit may not set back up when switching between the two 8410Ds, and then things are worst than before you began. As far as the type of switch, I'll do some research to see what's been proven successful for your situation.

Please excuse my terminology..
DOIM = Whomever your US Government Service Provider is...
"DOIM" is specific to US Army Installations.

CPT, (Sorry to keep posting)

I've been thinking on this.. even if this application of switching the same BRI circuit between the 2 identical 8410D instruments turns out to be successful, that does not mean that you are "good-2-go":

Each time you switch between instruments, your ISDN line would send a temporary "Out-of Service" condition back to your Central Telephone Office [CO]. If your local CO folks closely monitor their switch reports, this will not make them happy. They will assume that there is a problem somewhere between them and you [or worst yet...a problem with their switch!!]

As a CO Tech, I would not be happy finding out (after the fact) that the errors were caused by a "hybrid switch" solution at the far end, without consulting with the CO first.

If it's approved by your local service provider, and the 8410D switch does not cause temporary
Out-of-Service errors at the CO, I say "go-4-it".

Otherwise, my best advice is to approach your supervisor, to request they provide your co-worker with a Government issued cell phone to handle her outgoing calls, until they can install an individual line for her.

Sorry, but I just want you [and your CO folks] to avoid any unnecessary headaches.

I have a partner 4.1
3 lines to it if you open line 1 and call it is busy how do you get it to roll over
Thanks

Bill, this is a feature provided by your dial tone provider (LEC). They usually charge a monthly fee for this feature. It is impossible for any phone system to provide this feature using standard telephone lines, such as those used by the Partner. Call your LEC and ask them to arrange for the three lines to hunt. They will understand what this means.

You really should start your own new topic instead of jumping onto the tail-end of an unrelated subject. You might get faster responses to your questions.
