Re: ASK THE EXPERT - TELEPRESENCE

Is there a limitation on the number of H323 Video Endpoints to be displayed on a TP Screen during an Interop Multipoint call?

New Member

Re: ASK THE EXPERT - TELEPRESENCE

Currently you can display up to 16 video Endpoints during an Interop Multipoint call using a "Hollywood Squares" type format that is configured on CUVC.

Re: ASK THE EXPERT - TELEPRESENCE

Hi Tom,

This is not a technical question but more of a learning question if I was put in a situation to support TelePresence.

1. Is the book Cisco just released a good start?

2. Is a full understanding of CallManager needed or is TelePresence specific to trunks or device administration?

3. Other then the design guide on the Cisco site, do you recommend any other materials or reading to ramp yourself up on the Telepresence technical aspects?

Thanks,

Mike

Re: ASK THE EXPERT - TELEPRESENCE

1. Yes the book is a great place to start and I highly recommend it. Keep in mind that TelePresence is gaining momentum so this book should lay a strong foundation to build upon.

2. This is a good question but I believe you need to step up one additional level to consider all the components. The TelePresence session can rely upon multiple services and servers such as Call Manager CUCM, Exchange or Domino, CTMS, CUVC and CTS Manager as well as the network infrastructure. An installation tech can install a TelePresence system with a limited knowledge base of the supporting servers and applications however a TelePresence specialist and troubleshooter may be required to know all these servers and applications to be effective. At a minimum someone working with TelePresence should understand how SIP trunks work, how TelePresence endpoints and phones are configured in the Call Manager and how these items interact. To fully understand Call Manager CUCM would be nice but beyond the normal requirements needed to support TelePresence.

3. There are several documents on the Cisco.com and the Partner Portal that you should consider reviewing. The TelePresence Network Systems 2.0 Design Guide and the current Product Overview documents will give you a good understanding of TelePresence. The Endpoint administration guides and Assembly FRU documents will help with the deployment and support of the equipment. Besides these I would also recommend making sure you understand Room Design, Camera Tuning and how Latency, Jitter and Packet loss can affect TelePresence.

Re: ASK THE EXPERT - TELEPRESENCE

Hi Tom,

Do we have a Software/Plugin to measure and Generate a statement for TP Calls for billing purposes ?

I understand that from the admin page, logs and CDR you can gather data.

But have we got any specific utility just for TP?

Best Regards,

Neeraj

Cisco Employee

Re: ASK THE EXPERT - TELEPRESENCE

Currently a TelePresence specific plugin or software for CDR billing does not exist. All the TelePresence call processing is done through the CUCM so if you are looking for a simple billing solution a CUCM CDR billing software solution should work. The CUCM CDR data includes a field that specifies the type of call, what bandwidth was used and the calling and called party numbers. Based upon this information you could filter out all the TelePresence calls.

Thanks Tom,

More Questions

Q1.Are there any plans for removing remote for projector too ?

Q2.Are we planning to put specific Labels on the Back of Codec so that they are easily identfied. So that if someone has to disconnect and reconnect lose cables he is not confused.

Q3.Are we planning to add some kind of collabrative drawing tool which will further enhance the "experience" ?

Re: ASK THE EXPERT - TELEPRESENCE

Neeraj,

1. I am not aware of any plans to remove the remote however it is a Best Practice to place the remote in stored location instead of leaving it out. This is also the case for any Aux Display remotes once the monitors have been configured correctly and tested.

2. I am slightly confused on this question because the top of the codecs are all labeled and use a color coding. The larger installations can be more tedious because of the large number of cables however Cisco supplies a book of labels so that the installer can add their own labeling scheme. I do know that the 1300 has some additional labeling on some of the cables but that is because the unit has the cables pre-installed in the assembly.

3. I cannot disclose any information on unannounced products or applications so my answer at this point is that I am not aware of any new peripherals. If the demand is high enough I am sure the Business Unit will either develop or OEM a tool to fill this need.

Regards,

Tom

Re: ASK THE EXPERT - TELEPRESENCE

Thanks again !!

One more ..is there a proactive tool for monitoring latency, jitter etc ...apart from IPSLA routers.

Re: ASK THE EXPERT - TELEPRESENCE

Neeraj,

Here is a link to a white paper that discusses Managing TelePresence Networks and various tools to use. At the very bottom of the article there are additional links to the individual tools.

Re: ASK THE EXPERT - TELEPRESENCE

Hi : Does the Cisco TelePresence work over Satellite links (>600 ms latency)?

Any special configuration?

thank you

Cisco Employee

Re: ASK THE EXPERT - TELEPRESENCE

Cisco TelePresence System Software release 1.5 does support Satellite endpoints however a software license is required to activate this feature. The Cisco TelePresence System 1000 and Cisco TelePresence System 500 endpoint models are supported as the remote endpoint on the far end of a satellite link. You will need a minimum of 3-MB bandwidth (at 720p, good motion handling) in a single-channel-per-carrier (SCPC) configuration over a single-hop satellite link. Interoperability is not currently supported and only one satellite endpoint can be added to a multipoint call at this time. Because of the significant latency introduced with the transmission to and from the satellite noticeable delay is involved in the conversation. This latency will be noticeable during a TelePresence call. In addition, atmospheric conditions or other interferences may impact satellite-link performance and introduce jitter or packet loss into the call. If this occurs the result may be noticeable degradation of the video quality.

Re: ASK THE EXPERT - TELEPRESENCE

Hi,

Does the core Telepresence devices - CTS-Man, CTMS and CUCM support dual NICs? I am basically looking for LAN redundancy for these components by connecting them to 2 switches. Do they support NIC teaming like any other HP servers?

Regards,

Shashi

Cisco Employee

Re: ASK THE EXPERT - TELEPRESENCE

Shashi,

We support NIC teaming in our CTMS and CT-Man servers running TelePresence CTMS and CT-Man software release 1.5. We also support NIC teaming in our CUCM but you should verify this with your local reps because there are many variations of CUCM hardware and software. With NIC teaming enabled both NICs are connected but only one is active so this does not provide load balancing, only failover.

Tom

Re: ASK THE EXPERT - TELEPRESENCE

Thank you so much for the confirmation. Can you please provide me with any link or doc which provides more info about the same?

Regards,

Shashi

Cisco Employee

Re: ASK THE EXPERT - TELEPRESENCE

Shashi,

Here is the link to the CTMS Admin guide ver. 1.5. If you look under Interface Failover on page 4-28 it will show you how to configure the NIC teaming. Keep in mind that the interfaces are active/standby. Both NICs are connected to the network with only the primary NIC active until a failure is detected on the primary NIC, at which time the NIC in standby goes active. A virtual MAC address is used for both NICs allowing a single IP address to be shared by both NICs. As I stated in my correction above, NIC teaming is currently not supported for the CT-Manager but will be supported in the 1.6 software release. NIC teaming is supported in the CUCM but I would recommend working with your local Cisco rep to find out if its implemented in your current release and hardware.

Re: ASK THE EXPERT - TELEPRESENCE

Again, Thank you very much!! It definitely helps.

Cisco Employee

Re: ASK THE EXPERT - TELEPRESENCE

IMPORTANT CORRECTION: In researching the NIC teaming documents I found out that the code to support the NIC teaming on the CT-Man did not in fact make it into the 1.5 release but is scheduled to be included in the 1.6 release. So currently we support NIC teaming in the CTMS and CUCM today and will be supporting it in the CT-Man soon. Sorry for the confusion.

Re: ASK THE EXPERT - TELEPRESENCE

My company is installing TCS systems.

1. Is there somewhere a list of problems worth monitoring to assure the proper availability of the systems. (e.g. Registrations, Is it running, etc)

2. Is there an SNMP MIB (or SOAP schema) for the various boxes? Which boxes should be monitored for each solutions.

3. Are there performance metrics worth keeping an eye out for? How do you fetch them? SNMP?

4. Do these boxes generate SNMP traps? Is there a MIB for them.

Cisco Employee

Re: ASK THE EXPERT - TELEPRESENCE

Jerry,

1. On Cisco.com you can download the release notes for your software release. You can also go to the specific item under TelePresence product - such as CTS-3000 - and select Troubleshoot Alerts and then Field Notices which will list latest field notices. Using this information you can track any bugs/ddts using the tools on TAC web pages. Beyond this I can tell you what we see are some of the more common issues. The projector for collaboration can be an issue if its not set up correctly or if the user doesn't know how to set their laptop to the proper resolution. As mentioned in another response I would recommend testing the settings and then store (hide) the remote so that the end users cant change the settings. This also applies to any Aux. Displays as well. The network obviously can be a major issue and there are screens to help identify those issues - see #3 below.

2. Yes all the devices support SNMP v.3 I would recommend monitoring all the boxes.

3. There are performance metrics but there are also other tools to consider. If you have a CT-Man installed you can quickly look at the Support Dashboard for a quick overview or at the Room level to get the status of every endpoint as well as the resources such as the CUCM and CTMS. Also under the Troubleshooting tab there are system logs and log files that capture pertinent data. Every endpoint has a System Status on the Gui which gives you a quick snapshot of its overall health. Under the CTS Troubleshooting tab there is the ability to look at log files, system files and sip messages. Most importantly under the Monitoring tab you have the Call statistics and Network statistics. Both of these tabs are very valuable when evaluating a network issue. You should download and read the System Admin guide for the software version you have installed for more information.

4. Yes, please download the Cisco TelePresence System Message Guide for more information.
