Hi,
Only I know that we can use DRD cards for RF inputs instead of using DVBs as D9854
I know that there is DRD cards with 4 RF ports as below
DCM-DRD-4SAT4CI
DCM DRD Satellite Reception and Decryption board with 4 RF and 4 CI inputs
But I found the below 8VSB card
DCM-8VSB-8RF
DCM 8-VSB input card with 8 RF inputs
So can we use this 8VSB card to do the same function as DRD cards that it'll give more ports. Is there any limitation for this ?
Also what is the function of ASI card that I can't remember it?
Thanks

8VSB is ATSC standard which is very different to DVB-S standard. 8VSB is only used in America, that too for Terrestrial TV, not for satellite TV. So, you cannot use 8VSB card to receive DVB-S signals.
ASI card is an input/output card with 10 ports. Each of these ports can be configured as either input or output for ASI signal and can be used for basic multiplexing operation.

Hello Haitham
There is no 8 port card for DVB-S or DVB-S2 reception. It has only 4 ports.
There is a 8 port card for 8VSB. But, as I said, this is for the American ATSC standard, 8VSB which is for terrestrial transmission.
Regarding licenses, yes, you are correct. You need one license per RF port. So, if you are planning for 3 cards and using all the 12 ports, you will need 12 licenses. This license will enable only one stream per RF port. If you want to process multiple streams on each RF port, then another license is required which is called "multi stream license". Even with this one, you need 1 license per RF port.
If you just want to receive the signal, encapsulate the MPEG streams in IP and transmit the IP streams, you don't need MFP, coprocessor or transcoder card. These cards are required for additional processes like scrambling, statmux, Digital Program Insertion or transcode between MPEG2/MPEG4 etc..
You will need a GbE interface card for inserting ASI streams in to IP. In addition, since it is IP streaming, you may also consider using an FEC card for packet loss protection. Of course, it will also require FEC processing at the receiving end, where the IP packets are received..
There are set top boxes available from Cisco, but whether they are suitable for your purpose, depends on your system. It is best if you contact Cisco sales in your region who can best advise you. You can find the phone numbers at http://www.cisco.com/cisco/web/siteassets/contacts/index.html#~tab-f

Hi Kusridha,
Great. Thanks a lot for your answer
So there is only the 4 port DRD card and there is no 8 port new cards from Cisco
only I have another question
do I need a license for each DRD port. So for 3 cards. I'll need 12 license ? Also do I need MFP or Coprocessor or transcoder cards for normal IPTV installation? Also is there a set top box from Cisco or it is only from other vendors 3rd party?
thanks again for your great info

Hi Kusridha,
Thank you very much for your great info. It is very helpful
Only I'm confused about your words about multiple streams per port
" If you want to process multiple streams on each RF port, then another license is required which is called "multi stream license". Even with this one, you need 1 license per RF port"
Is multiple stream mean that I can use one frequency per port but multiple channels and every channel will have its multicast IP. or multiple stream mean multiple frequencies per port which I don't think it is doable ?
If you can share me the IPTV ordering guide, It'll be great
Thanks again for your help
Best Regards

Hi Haitham
You are correct about the multiple streams. You can have multiple channels in one frequency. It is not multiple frequencies per port.You can only have one frequency per port. You can have multiple channels in one frequency and once the RF is demodulated, you can see ASI stream which may contain multiple services (or channels). You can then pass each of these services to the GbE card as output and assign individual multicast IP addresses to each service. Alternatively, you can have the same multicast IP address, but can assign different port numbers to each service.
I do not have any IPTV ordering guide, since I am from Technical support division. As I said in my earlier reply, it is best if you contact the regional Cisco sales office.

Hi Kumar,
Kindly do you know what suitable SFP for this card DCM-GBE-MK1 ?
Thanks

Hi Haitham
The DCM data sheet available at http://www.cisco.com/c/en/us/products/video/multiplexers/datasheet-listing.html lists all the SFPs that are suitable.
I am also attaching the data sheet here.

Hi Kumar,
I have allready used SFP-GE-T that I found SFP-CU-RJ45 that is mentioned in datasheet isn't available anymore
Thanks again

Hi Haitham
I am not sure where you got the information that SFP-CU-RJ45 is not available anymore.
I checked our on-line price list and it is still available.

i have a client who has a project which consist of 1380 apartments. they asked me for classic sat tv solution for their apartments. instead i offered them cisco ip headend for better solution. i have never done this before. i m working for this for two weeks still i ve questions. i contacted regional cisco sales office and they told me "we never did this kind of project in Turkey. so if you tell us that which products you need and we ll give you price offer"
but as i told i have never done this before. it will be my first dcm project. i learned much but still need to learn a lot. my client wants 4 dish and terrastial. which products do i need besides DCM 9902. can i connect lnb to RF input ? can i use ip lnb and connect it to gbe card ?
i dont want to be very sorry against my client because of offering cisco solution.
i ll appraciate for any help.
thank you

Hi Reha
Without knowing the full requirements of the system, it is difficult to answer these questions. This forum is mainly to answer general questions.
Customer specific designs like these require some expert from Cisco to look at the requirements and propose the appropriate solution.
Your local Cisco office should be able to point you in the right direction and provide the required assistance.
