As you can see the Network ID and Original Network ID (ONID) should be the same in all
units and preferable the same ID as the Main Cable operator use (in Sweden ComHem
are using 41001 as Network ID). Network ID could have another value than the ONID but
most of STB:s and TV:s with inbuilt STB will accept same ID for Network ID and ONID.
To avoid problems between two or more Muxes in a Headend it’s recommended to use
different Transport Stream ID (TSID) for each EXM unit in the same Headend. A rule to
make the TSID easier to remember is to use same TSID as the last digits in the IP
address of the unit. This also makes it easier to remember if a unit shall be replaced.
NetworkProviderName is possible to change. However, if you do not know what STB:s
and TV sets customer use it’s NOT recommended to change. If the owner of the Headend
also provide all STB:s to all households in the Cable TV network this could be changed.
The choice of Logical channel type is depending on in which country the installation is
made. For the Nordic countries the correct choice is ”Nordig”. This should be chosen only
in the unit with the outgoing MUX i.e. in other units the correct choice is ”Undefined”. For
other countries refer to your DVB specification. Beside Nordig you can choose between
EACEM and Independent Television.
(See next page for configuration of Mux #2)
NOTE! All three units has SW option EXM-RC.
