ISDN BRI Network side to Video conferencing unit

I would like to know if I can use a Cisco router (1760) to provide BRI's to a video conferencing unit. I would like the router to be configured for the NETWORK side so essentially it appears as the PSTN. At the main site I have a Cisco CallManager server that I would like to take in video calls from other offices and have CM basically perform the call setup to the video device connected to the 1760 router. The 1760 would connect to the CM via MGCP.

Unfortuneatly not - IOS will not switch non voice calls through BRI ports - video calls use a data bearer capability.
There is video support coming out soon for Call Manager - keep an eye out for it.

Cisco 4-Port ISDN-BRI Network Module

Cisco 4-Port ISDN-BRI Network Module
what does the BRI mean?
I have this module in a 2600 series router. Can it be used for basic LAN connection (like a hub)?

First, to answer your question: No, you cannot.
ISDN is a Telco technology and protocol suite.
"BRI" stands for "Basic Rate Interface," also described as "2B+D" for two Bearer channels and a "D" channel, which is used for control signaling in some configurations, and additional bandwidth in others.
Max throughput is either 128K (2 X 56K or 64Kbps per channel) or 144Kbps (2B+16K that may be available in the D channel depending on your config.
ISDN requires an intermediate telco-style switch between the clients and can't be used back-to-back directly.
Good Luck
Scott

ISDN2 Back to Back conf (VIC2-BRI to Video Conf Unit) is this possible?

I have a VIC2-2BRI-NT/TE which I need to connect to a Video Conferencing unit. I have configured the following but I'm getting no layer-1.
interface BRI0/2/0
description *** VC
no ip address
isdn switch-type basic-net3
isdn protocol-emulate network
isdn static-tei 0
I have tried both straight through and ISDN crossover cables as below.
3 -> 4
4 -> 3
5 -> 6
6 -> 5
Can anyone offer an advice on this?
Thanks,
Chris

The following URL might give you some more ideas on how to do TDM switching through the BRI/PRI voice ports -
http://www.cisco.com/en/US/tech/tk652/tk653/technologies_tech_note09186a00804794c6.shtml
If you are outside of North America, remember to set the companing to a-law on the voice port - once the call connects the DSP will be dropped and a pure TDM connection made as long as the E1 and BRI companding are the same.
Some external BRI devices don't like to negotiate a TEI, so you can set a static TEI of 0 using the D channel command 'isdn static-tei 0' and doing a shut/no shut on the interface.
If this still does not help, run a debug ISDN Q921 and log the results after plugging in the external unit and performing the shut/no shut on the D channel.

Test Plan for Video Conferencing

We are planning to set up an MPLS network exclusively for video conferencing. I need to prepare a test plan for the tests to conduct to check the conferencing performance and related parameters after the implementation.
I am pretty new in Video conferencing. May someone help me to prepare a test plan for this?

Do you have some more details about the equipment and setup you want to test.

Implementing video conferencing in an existing voice network

I have been tasked with adding two Polycom video conferencing stations to our existing LAN. Currently, we have Voice on VLAN 100 and Data is on VLAN 1. (I know, I know...VLAN 1 ). AutoQoS has been enabled on our switches. My questions: 1) Should the two VC stations be assigned to their own VLAN? 2) Is AutoQoS still an option for me?
This site is connected to our others via VPN over broadband. I realize I can't do end-to-end QoS using this WAN connection, but I'd like to try and push the video to the front of the line as it leaves.
Thanks for your time.

Hello,
Yes you can add your Jetpack to your existing WiFi network, but it is going to take some configuration to get the job done. What you need to perform is a process called "Cascading" your routers together. In a nutshell, two routers cannot exist on the same network unless they know how to communicate to each other. You need to setup the routers so that one is the Primary and the other is the secondary.
How to Cascade Routers:
http://www.wikihow.com/Cascade-Routers
However, the catch with cascading routers when a Jetpack is involved is that a Jetpack is a wireless only device. The USB Tethering feature of the 4620L will not be sufficient for cascading, it must be a WiFi connection that links the Jetpack to the other router. You may have to swap out your current home WiFi router with one that has a wireless bridging feature. A quick example would be the Pepwave Surf Mini.
Here is a diagram of how the new home network could look:
Take a look and let me know if you have any questions. Post your home router model for us to review if you are curious to know if it can connect directly to the Jetpack or not.

Video conferencing & ISDN

I am waiting for my new iMAC with isight built in. Can anyone tell me whether it is possible to hook this up so I can do video conferencing to standard Polycom/Tanberg video conferencing equipment over ISDN lines?
I have ISDN 128k at home (BT Highway) and want to connect to a couple of hospital video conferencing facilities in the hospitals I work in. More or less everything is PC based in the NHS so it's no good asking anyone in the IT departments!
Look forward to your reponses.
Andy

Hello Andrew,
Welcome to Apple Discussions.
I have never used a Poiycom video conference, but, from reports posted here, ohphoneX
b may
be able to do what you want. See its web site for compatibility info, system requirements, and instructions.
Your Polycom/Tanberg Video Conference System Administrator will have to help you with its requirements and what and how you can connect to that system.
If you search iSight Discussions (up one level) for "ohphoneX" (without the quotation marks) you will find several links related to Polycom and other video conference systems.

Mac to PC Video conferencing: OhphoneX to NetMeeting

Most of the Mac to PC Video conferencing posts talk about iChat AV via .Mac/ AIM screen name to AOL Messenger.
For those wishing a larger video size one could replace AOL Messenger with Trillian (http://www.trillian.cc).
We, on the Mac side, are blessed with the ease of use of iChat AV.
The set-up, on the them side, the PC side, is a bit of a hassle for your poor family and friends who barely know how to shutdown their PC with the Start button.
Why not let the Micros~1 Windows 2000 / XP users enable their packaged NetMeeting software.
I recall from my dark ages that NetMeeting was serving its purpose with adequate proficiency (Isn"t that a "contradixio in terminis").
OhponeX claims to be compatible with Micros~1 NetMeeting.
http://xmeeting.sourceforge.net/
The installation of Ohphone on the Mac is .... simple.
The activation of Micros~1 Netmeeting .... requires the filling of a few set-up screens.
Now find each others IP address:
In OhphoneX this is displayed on the main screen
In Micros~1 NetMeeting, go to Help, Click About and there the IP(s) are listed.
Enter the IP in the callto screen and press enter.
On the Mac side you can click Connection Statistics to see the in/out streams for both audio and video.
The mentioned OhphoneX website has a good manual.
The lovers of OpenSource will dig the code.
One next step to be solved: connection across LANs.
Within the same LAN I"ve got this Mac to PC connection working.
Cross LAN I got stuck with NATs and router ports.
Any help out there?
Regards,
Coen Jeukens

OK, Bill, <big><big><big>☺</big></big></big>
Coen and I have chatted about this.
I believe that he posted this thread to assure those who wonder whether OhPhoneX can connect to NetMeeting conferences know that
b it can. Coen, please correct me if I am wrong about this.
I have never used either OhPhoneX or NetMeeting, but Coen tells me that this info will be of value to iSight users wanting to do so.
As related to Coen's
]"One next step to be solved: connection across LANs.",
Bill, if YOU can't answer this one, I do not stand a chance!! <big><big><big>☺</big></big></big>
If Coen does not get needed answer from someone here, I suggest he might find better help from http://xmeeting.sourceforge.net/ or in the Tiger > Getting Online & Networking Discussions area.
That is the best I have to offer.

RV082 and video conferencing

RV082 router is not allowing video conferencing through to Polycom 7000 HD. voice comes through but no video.
Have tried several things.
1.) necessary ports ( Polycom provided) forwarded to designated internal ip / firewall acess allowed ( external ips to designated internal ip ) respective port Qos set to high.
2.) set dmzhost to designated internal ip address. Respective port Qos set to high.
3.) enabled Upnp with necessary (Polycom provided) ports forwarded to designated internal ip address.
Is something missed?
Other option is obtain second external ip address and connect to DMZ port. Trying to avoid a second external ip.

multicast passthrough is enabled.
At this point I am leaning towards a bandwidth problem. Since this unit is sharing the local network - there may not be
enough bandwidth the support the video signal but sufficient for voice.

Video conferencing deployment

Hello,
I work in a hotel, and we intend to deploy video conferencing service to guests and management. Can anyone please help with products, design etc(new to video conferncing). Our internet connection is thru VSAT. Please advice
Thank you
Daniel.

Hello,
Video conferenceing requires large amounts of bandwidth and is even worse than VOIP in reguards to jitter and quality. You have a couple of options depending on what your wanting to do for conferencing.
Polycomm and Tandbergs are two major manufactures of video equipment. I'm not familiar with the tandbergs other than there more ruggged.
If you looking at only doing two sites the equipment is fairly easy but if your looking at haveing anything more than three sites conferencing at the same time you'll have have to look into bringing equipment that consolidates all the streams and sends out one to each of the conferencing units.
Polycomm VSX7000 have the ability setup a conferene to two other video units.
If your looking at doing conferences of ISDN you'll have to look into getting a gateway if just ip it's fairly straighforward.
Its probably best to contact a video engineer group like the chariot group.

Video Conferencing in IPT

Hi,
We have IPT setup in our customer location. With CUCM cluster and PSTN PRI for in/out calls and using microsoft exchange for VM.
1. How about deploying Video Conferencing setup in the above IPT environment or do we need to take seperate BRI's for that ?
2. If yes so, do we need any additional hardware like Router, cards or modules etc...
can someone advise..

Tommer is absolutely right about defining your business requirements and clearly define *who* you want to do video with first. If the answer is "anyone" then someone is wasting money because they actually have no one specific in mind. There needs to be specific use cases that can make an impact to the business.
A few technical things to add though:
Video support over ISDN is covered by the ITU H.320 standards. Cisco IOS does actually support H.320 video gateway functionality now. This was added very late 12.4T or early in the 15.0T trains (use feature navigator to be sure). The configuration is somewhat complex though and requires some time to figure out. H.320 Video - ISO/IEC-13871 Bonding
Cisco IOS can also perform the MCU functionality now starting in 15.1(4)M if using PVDM3 DSPs. This is very resource intensive though so be sure that the DSP calculator is run; it now has an extra page for video conferencing. The Tandberg Codian MCUs will still provide a much larger feature set. The good news is they can also register to CUCM now or in the near future as a video conference bridge.
When doing inter-company video CUBE is a valid option but it predated the Tandberg aquisition. You may want to consider the VCS Expressway now as it seems to be the product direction. Personally I suspect it will eventually be the downfall of IME but that's just unfounded speculation.

Hi,
The media traffic bandwidth usage can be challenging to calculate because of the number of different variables.
You need to calculate with codec usage, resolution, and activity levels.
Please calculate with the help of the link below of “Network bandwidth requirements for media traffic in Lync Server 2013”
http://technet.microsoft.com/en-us/library/jj688118.aspx
Also, please double check if you meet the hardware requirement for Lync Server as well.

Designing Cisco Video conferencing solution

Hi All,
I need to design a single site Cisco IP Video Conferencing soultion which should support web, chat, ISDN and email etc support.
there will be one conferencing room which will be communicating with other remote or traving users.
the requirement is that remote or travelling users should be able to have the video conferencing facility with the Headoffice(single site) and vise versa.
Any help will be much appreciated.
Regards,
Waqas

I would recommend Cisco unified presence server for your deployment with MPX. That will give you chat, voice and video conferencing. If you dont use MPX then you can only do point-to-point video CUPS on its own doesnt support video conferencing.
YOu can also intergrate with exchange to view meetings and unity to listen to voicemails.
You can use VTA for the remote clients and 7985 for central site or some sort of tanberg phone if you want a larger screen.
The remote users are going to have to have a pretty low latency connection to get good quality video/voice.

IP Video conferencing best practice - Tanberg/Cisco hardware

We are currently experiencing intermittant issues with our Video conferencing internal and external network with intermittant screen fragmentation. We have separate VLAN's configured on our internal network for the Video traffic only. We use the movi client on the with the majority of our remote users. I'm wondering what is the best practice based in setting up and support a Video conference network.

Have you set up QoS policies for video?
I have a very good network readiness document you are welcome to, if you want to ping me your email address?
I can't seem to copy it properly into the tech support app on my iPad, drop me an email to [email protected] and I'll send over the info - should help!
