ISDN PRI E1 Issues

[EngMajdi82]

Hello,

I have an IPO 500v2 Rls.9, having Phone2 Base Card fitted with an ISDN PRI E1 trunk card with 8 channels, no additional license customer purchased.
The ISDN PRI EI Interface coming from orange have 15 channels.
The Customer complains that sometimes all they can't make calls and receive calls.
After test and check the problems through the SSA and SysMonitor found that the PRI working on linear state as follows :

Channel 1 (Orange PRI) - Channel 1 (IP Office)
Channel 2 (Orange PRI) - Channel 2 (IP Office)
Channel 3 (Orange PRI) - Channel 3 (IP Office)
.
.
.
.
Channel 8 (Orange PRI) - Channel 8 (IP Office)

From Channel 9 to 15, when dialing the number just silence for no limit time, no busy tone or anything. when calling the number is busy.
This case is repeated until you reach the channel 1 again or power off the IPO and restart count the channel again.
We call the orange telecom to down the lines from 15 to 8 Channels, and answered us that is not acceptable
and the customer don't want to purchase additional 8 license, because no need of it.

Is there any workaround solution to solve this issues ?? I remember in Avaya CM we can choose round-robin cyclical than linear, this cause that any channels coming from line provider goes to any free channels on CM.
Hope from experienced here suggest a best solution for this ?

Thanks you and Best Regards

on the pri line at channel allocation change it from 23-1 to 1-23 and make sure you have channels 9 to 23 set to out of service, never had to do this so give it a try

Set the number of voice channels in the Pri line to match the number of channels supplied by your Telco

If you have 8 then set the Pri to 8 outgoing channels

Hello joe2938,

I have PRI 30 E1 non PRI 24 TI.
Is this will work because the channel allocation now is from 1-30
When set to PRI 30 E1 , there is a new Numner of channels option with 30 channel set, and the error message still appear (the number of channels configured on Universal PRI lines exceeds the number of licensed channels)
But when set to PRI 24 TI, the number of channel option and the message disappear.

Advice me Please ?

Thanks and Regards

did you only set 8 channels into service? and change the order from 23-1 to 1-23, also when you changed it to pri 24 ti did that resolve the issue, I am in the USA so have not worked on PRI 30 E1. only have worked with PRI with 23 b channels and 1 d channel for signaling

Hi Snowman50 ...

I set :
Number of Channels : 15
Outgoing Channels: 8
Voice Channels : 15
Data Channels: 8
The Message (the number of channels configured on Universal PRI lines exceeds the number of licensed channels) still exists.
On the Channels tab there is 15 channels but the line appearence starts from channel 9 - 15

Best and Regards

The exact number of Carrier's ISDN PRI Channels should always match the number of licensed ISDN channels on the system.
You may change the order you seize PRI channels on outgoing calls by assigning PRI Line Appearance Numbers in order (701,702,703,703..) instead of Line Group IDs on your ARS table.
However you cannot adjust the algorithm of channel allocation for Incoming Calls from the carrier.

Set the line type to ETSI-CHI instead of ETSI. That way you can configure each channel individually.

Hi derfloh,

I set the Line SubType to ETSI-CHI, Channel allocation (30-1), but on Number of channels what should I set, 8 or 15 ?
if I set 15, on channels tab keep channel from 9 to 15 out of service.
now whats happen if the calls come from line provider to channel 9-15 ?

Please Advice ???

Best Regards and Many thaks

Only way it makes sense is to either tell the provider to use only 8 channels or buy additional channel license so that IPO is licensed to deal with 15 channels.

The end customer doesn't want that IPO will not answer call number 9 and the caller gets a message from provider.

Hello derfloh,

I Know that the better and only solution is either the line provider use only 8 channels or buy another additional 8 channels.
but as I described the Orange telecom cant down channels from 15 to 8, and the customer no need to add more than 8 channels license.
for now just I need a temporary solution until we find solution either with line provider or customer.
in your earlier replay suggest to use ESTI-CHI instead of ESTI, and Joe tell me to set channels from 9 - 15 out of services.
is this acceptable to solve this temporary ?

Regards

For outbound it should work that way. You have to talk to orange if they use the channels from 1-8 (or 15) or vice versa or round robin. If the do it round robin you will not have a chance.

Hello,

if I plug another phone2 with ISDN PRI card, can I use the 8 channel coming with card 2 to the working card 1, so we temporary solve this until find the best solution between customer and orange ?
do you know why? because its the first time we buy PRI without additional license so before we dont have any problem or customers complains about this, and this the first time our company buy without additional license, and as I said before the customer no need additional license to buy and the orange said they cant down the PRI channel from 15 to 8 ?

Thnaks and Regards

I never tried that. But it could perhaps work. You will have licenses for 16 channels. Set the channels for the second PRI to 0 or 1 and to 15 for the first one. To be honest I don't know if the 8 channels will be bound to the cards (8 each) or I'd they will be available in the system and usable cycle all installed cards.
