TLU76 - TLU79

[vince62s]

What is the difference between TLU76 and TLU79 ?

there are a bunch of connectors on the TLU76 but only the bottom one is connected to a 30ISDN box

is the only difference the fact that TLU79 has only 4 channels?

thanks

Sure if IP trunking is just what he wants ....

BUT

corporate WAN = Internet ??

What do you mean with Internet ?

Your routers will now have the possibility to
dial-up to your ISP's servicenumber if
you pass the accesscode for PSTN+ISPnumber to
the tlu76 connected to your router.
The internet ISP call will then go trough the md switch
and out on the TLU76 connected to PSTN.



The same time you will have qsig connection
for internall calls over ip between site A & B .

 

[vince62s]

this sounds great.

now how do I configure the TLU76 (2) for:

1) initiate dial up on TLU (1)
2) route the information properly.

 

[mdfan]

Wouldn't this imply the PBX act as a ip-router ?
Indeed if possible , a very nice setup ; so SYAR2003 pls
tell us how ? (we will pay you well )

 

[SYAR2003]

It's just to setup the RODAI ROCAI RODDI
as QSIG networking with closed numbering plan.
The MD data should be setup to support GFP (Generic Functional Protocol) and to tunnel UUS data through GFP.
The cisco ip-routers must be enabled to support QSIG w/GFP from the g.703 interfaces .

Something in the MD like (for BC11)
VARC=00000310,
VARI=75440000,(1-30 channel numbering)
VARO=06300000 or 06400000 ( network or user)
SIG=111110000031
ADC=150510000000025010500000
SERV=0110000001
SEL=X11000000000001

Rest is in the routers witch is not my field i'm afraid.


Match the VARO's user side/network side to correspont with the routers to get the d-channel established.

Isn't this what is needed between (2) and (4) ?

Are you saying that this automatically gives the ISDN internet backup between (2) and (1) ?
This is what vince wants.

 

[SYAR2003]

That is configured in the ip network /routers.
Im not saying anything gets automaticly done.
It must be configured to work .
How thats done in the routers i cant answer.
If 0 is the access code for pstn at (1)
the router in sita a has to dialup to (2) 0 + isp
number and logon to the ISP.

Other internet routers must be updated by this route
so thay can have it as a backup route to internet.


This setup makes all that possible if someone that
has the right expertise can configure it correct.
And the two md's is also qsig networked over ip.

"Dont hijack the tread"

 

[mdfan]

Have you done this router configuration ?

I am trying or planning 2 different things:

1) internet access through ISDN for backup purpose. I dont want to order a new ISDN line since I already have these 30 channels. My idea is to connect the cisco router to a ISDN interface of the MD 110 , then I could have internet access.

2) My other plan is to have a remote site connected to the internet and have voice over IP with the TLU76 connection to the cisco router.


Isn't this what we have covered here .

SYAR is correct this is no problem in achiving this. Though you will need special cisco hadware and a good cisco technican. We have been running both this senarios and number 1 is a easy thing, number 2 deamands special IOS software in the router for IP telephony.

Thanks Fredrik.
There is also a Cisco router forum here

SYAR,

will the config you mentionned VARI,VARO,... work with BC10?

also I have a E1/PRI cable with one end 13 PIN connectors going into the ctrl of the router, on the other end a RJ45. SHould I assume the RJ45 is a regular double pair tx rx?

what will be the actual speed between the MD and the router?

 

[SYAR2003]

I have to look at the parameters again.
What BC10 cna version is it.

The connection to TLU76/1 is regular pair yes.
The board should come with a connection
cable for pair named TSR 901 0481.
If you don't have it ,order it from your local MD110
provider .

Actual speed , i don't understand .
This would be the same as having a ISDN from PSTN
connected to your router. It depends on how it's setup
to dial the ISP (number of b-channels to establish)
One b-channel is 64kbit.
It's upto you and a cisco technican to decide .
Just don't take so many channels that if effects the
pbx voice traffic .

And do as Fredrik says consult a cisco technican with
experience of setting up voip on cisco equipment.

There might be some licenses in the MD you must purchase also if they arn't in the system already.
