Dual BRI - Trunk out of service 2

Hey guys/gals,

Bit of a lengthy post;
To start I'm not entirely sure who our providers are, hence the post here first to potentially gather some information, nor what the setup originally was and what I now have available from that.
We have an IP500 V2, Manager shows version 9.1.6.0 build 153.
This was all set up before I started at the company and we're looking to make a few adjustments.

Basically; IPO Manager shows 4 BRI lines, sub type ETSI, lines 1, 2, 5, & 6.
In IPO System Status > System > Control Unit
there are are two slots, each has a 'Combo Phones/VCM Module (8)' and 'Trunk Module (Dual BRI)' listed.
Each of the Trunk Modules lists 2 ports.

In slot 1, I see two ports each with 2 channels, all of which are administered and their state is either 'Connected' or 'Idle' which is fine.
But in slot 2, both port 1 and port 2 have 2 channels and none are administered. Both channels show their states as 'Out of Service'.

The card in slot 1 has ports 9 and 10 connected to our lines in (presumably).
and where each of these is connected there are two ports (totaling 4, which would match the 4 lines the system could utilize).

So my understanding of it is that we can only have 4 concurrent connections, due to the dual channels on two lines.
We would like to make use of the other two lines but I'm not sure whether they're even live, so my first question would be what are the chances the other two lines will work? And if they do not work, does anyone know why it would be installed with two sets of two ports, where one of each set is in use? Why not just use the one set and use both ports of that..?

I made the assumption that since it's set up the way it is the other two lines will work, and connected one to port 9 of the second card, but to no avail, attempts to call out from one line would often report 'waiting for line' or not dial out at all, but occasionally would. If the line will work is there anything that can be done on our end to set this up, or is it going to be need to be activated externally?
The labels on the ports are branded by Openreach so I'm assuming I can get info from BT about how to activate the two other lines, if possible, but I thought maybe whoever set up the system might act as the middleman for this instead, and is there anything that I can look for to indicate who I should be contacting to get someone out to make the amendments we are looking to make?

I've been looking through Manager myself, and using the help and guidance of yourselves on here which has been a great help. But when I inevitably hit a roadblock I'm not sure where to look for the engineer.
You'd think there'd be some paper trail of the purchase and the installation, but apparently we're not that organised and it's been 4 years...

Anything you can offer would be greatly appreciated,
Thanks.
 
If you have another (second) NTE that looks like with a green light on it, then it might be live. Plug a cat5e cable into it and then into the ISDN2 socket on the IPO.

If not, you will need another one installed. (the bill you pay should have all the info on it.)

Thank you for a quick response.

We have the second, only one port on each (the first of the two ports) is in use.

the one on the left goes to port 9 (it's kinda tight, runs across the bottom, but I don't want to fiddle with it to loosen it a little in case I screw it all up), one on the right runs to port 10 here;

The whole thing's a bit of a mess, but that's what I've been left with.

Does the green just indicate no problems, or does that mean that both lines from it are functional?
Would you have any idea about what may have caused the 'waiting for line' message when dialling out with the other port of the left NTE connected? (edit: should clarify that no other calls were being placed/received at the time of the one phone having problems)

Thanks.
 
Please excuse the double post, but are ports 9 through 12 all trunk ports?
And should the other two available ports on the NTE's be plugged into 11 and 12, and not 9/10 on the second card?

Thanks, again.
edit: little bit of investigation, the card itself says what 1 - 10 are, but no idea about 11/12

You need more lines from the provider, you only have 2 ISDN2s (4 channels) and you are using them both/all. So to connect more to the system you need to buy more :)

 
P.S That looks like a BT installed system judging by the wiring loom they use :)

 
Then, if that's the case, what's the purpose of the other port on each?

And why does Manager list 4 lines? where two of them are out of service?

1 and 2 are card 1 ports 9/10, and 5/6 are listed as card 2 ports 9/10
Can't wrap my head around why it's set up to have two useless lines...
 
ISDN2 lines can act as a Bus (PtMP), so you can have 2 devices with a unique identifier each having one channel, that's what the second port is for, it's not used these days.

The second pair of ports (BRI 5 and 6) is the system having those available to connect the lines to, but you don't have enough lines to connect to them...you need more.

Ports 11 and 12 on those system cards are unused, you have a BRI4 daughter board fitted (2 ISDN2s), on other cards you can fit BRI8 daughter boards that allow 4 ISDN2s to connect.

The cards you have also allow digital and analogue handsets to connect, that's why they're there I guess. If there are no handsets connected then it was oversold or sold with some expansion room :)

 
Thanks amriddle, that clears a lot of things up.
We'll manage with just 2 lines, we have done for as long as I've been here, but good to know where I need to be going to get more sorted.

Knowing management it was likely oversold, and an easy sell...
But does give us a little room to work with.
I better get back to taming the AutoAttendants and HuntGroups, no one else here is willing and I'll be damned if I'm calling someone out for that [wink]
 
While saving money is always a good thing, spending some to keep us in jobs is always better. ;-)

I dont think you were oversold on this occasions

there are only 2 variants of the BRI card available Bri4 & Bri8 (the combo card you have only supports Bri4)
so you do have the minimum equipment possible to support your usage

ading another ISDN2 if you find you need it is easy, to expand beyond 2 circuits (4 channels) you will need additional hardware


Do things on the cheap & it will cost you dear
 
They may have oversold, BTLB do it a lot. They have 2 combo cards fitted there and only one appears to have any phones live, even though they've cables it up. So it's oversold or allowed for expansion :)
