Hello,

I am attempting to install a new telephone line on an officeserv system. The system currently has 6 phones that are working and i want to add a seventh. When i plug the phone into the jack where i want the phone installed, the phone comes on, listens the version number, then shuts off and repeats itself. If i plug the phone in at the officeserv using one of the available ports, i get the same result. However, if i plug the phone into one of the existing ports, it does work.

That leads me to believe that there is an issue with the officeserv settings, but i am unsure what to do. I tried to use the lan connection via an ip address i set up using 831 to see if i could see some settings to change, but i could not get the officeserv webpage to load.

any ideas would be appreciated

The phone should come up without any programming.
Check to see if the 8th port comes up.
Sounds to me you have a bad port.
How is it equipped?

Sounds like you might be trying to plug into a single line port. The 7100 the ports on the cards don't go staight across. Look for P3 on the second digital card it should be under P1 not next to P2.

Thank you for your replies.

On my 7100 there is a card with 16 ethernet jacks, close together. Each of them have an rj45 connector with just a single pair connected on pins 4 and 5.

All 16 ports go to a punch block that connects to the phone lines going out, it seems like the phones only require the single pair.

The ethernet jacks appear to be split into 4 groups of 4.

Phonman, the phone seems to constantly reset itself. I have also tried to plug it into a different unused port and get the same result.

John, it goes,like this


..1.........2........3........4
p1 p3 p1 p3 p1 p3 p1 p3

p2 p4 p2 p4 p2 p4 p2 p4

i am plugging into 3, p3 directly with the phone and up the phone reboots itself,
however if a plug it into one of the lines that is already working, 2, p1 for instance it will start.

I hope that makes a little more sense.

Looks like this is the module

That is a UniCard. It has 3-4Port modules that it can accept.
I can accept a 4Port Loop trunk, 4 Port Digital Station or 4 Port Analog Station.

You probably have bad ports or as John says an ana
log module in the third position

Thank you. I think i am understanding what you are saying now.

Is it possible that the third position was left blank by the original installer? If i wanted to install a 4 port digital station in the third position is it just a matter of removing the unicard and replacing the card in the third position with a 4 port digital station?

You can tell what cards are installed by the color of the LED's on the UNI card. Red is for DLM Green is for Trunk Amber SLI OFF is no card
If the P3 slot was empty you wouldn't get anything when you plugged a phone in. Being a 7100 you could / can have a digital 4 port card on the MP10/10A card as well.

If the phone system has 6 phones working on it already means there are 8 DLI ports available. Like PVJ says, the DLI cards are identified by the color light that is lit up on the uni-card. I would check and see if the P1-P4 are used on the processor, that can also carry a DLM card. Look at where the other card is, looking for the second p? with red light. Then you can plug it into there.

guys, thanks for you help.


It ended up that 4 ports were up near the lan module built in with the unit and four on the unicard. My questions now I have one spot free but I would like to add two phones. They could be on the same extension. Is there a way to do that using only one port? E.g., so that the phone mirrors the other phone (only one used at a time)?

If not if I get another unicard with one modem for the ds-phones is it just a matter of plug and play?

the current unicard has 4 ports for dlm, 4 for trunk and 4 for sli.

If what you say is true. Then the system is currently equipped for 8 digital phones, 4 co lines, 4 single line extensions. Therefore if you had 6 originally and want to add 2 more, you should have the available 2 spots to do it. Looking at the processor card, there are p1-p4 those are 4 digital extensions there. Then look at the Uni-Card, to the right of it are 3 lights. Whichever light is red, look at the p number. Then look at the card, the P1-P3 are all setup in groups of four. 1,2 on top 3,4 under 1,2 for each card on the unicard. If you have 7 things plugged into the digital stations, then you have a jack somewhere that is active and not being used with a phone. I would test by dialing the extension numbers. If only 201-206 work, then you have only 6 in use. Dial 207 and 208 to see if they are active. Be aware that they might have skipped a port or 2 in installation. Just try calling each extension from 201 and see which ones are not in use. More than likely your system will be setup as 201-204 on the processor card and 205-208 on the uni-card, the first 4 ports going from top to bottom.

Use to be a two port card maybe the dlm is one card have you checked in programming to see what cards are on system

Never seen a 2 port DLM card on a 7100 just the 7030
