multIstreAmIng ArrAngements
The following includes two examples of
Multistream
arrangements involving the MultiRack. In the first
environment, the MultiRack that is serving the Multistream initiates calls, and in the second, the serving MultiRack
accepts all of the incoming connections.
multIrAck InItIAtes the cAll
In the “Multistreamer as caller” model, two different profiles will be built on MultiRack A. The first profile, labelled
“Multi-Duplex”, will be defined as a standard, duplex MultiRack connection. The encoder to be used will be selected
in the
Local Encoder
section, and the stream desired in return will be defined in the
Remote Encoder
section.
The second profile is called “Multi-Simplex” and in this profile the
Remote Transmitter
is turned
Off
. Most other
selections in this profile are irrelevant. User A will define remote connections for MultiRack B, C, and D. They will
assign the “Multi-Duplex” profile to MultiRack B, and “Multi-Simplex” profile to the others. They will then establish
a connection with MultiRack B first, followed by C and D.
multIrAck receIVes the cAll
In model number 2 where the serving MultiRack accepts all incoming connections, all the profiles are built on the
Remote Receivers
. MultiRack B will use a simple profile by defining the encoders in each direction, and assign it to
MultiRack A. MultiRack C and D will each define a profile with their
Local Encoders
turned
Off
, and assign them to
A. MultiRack B should connect first. When C and D connect, they will hear the same stream as B, regardless of how
their
Remote Encoders
are set in their profiles.
In a
Multistream
environment, the first man wins. For example, the first connection made between units will
determine the encoders used for all others. After the first full-duplex connection is made, all other attempts at
full-duplex connections to either end will be rejected.
usIng crosslock wIth multIstreAm connectIons
CrossLock functionality in Multistreaming has been introduced with MultiRack. Previous Comrex Access Racks
did not support CrossLock VPN when performing a
Multistream
. With the introduction of MultiRack, the added
broadcast reliability of CrossLock brings increased connection stability in Multistreaming environments.
