12 CONVENTIONAL IP NETWORK / 12.1 Communicating with a Repeater Connected by Using an IP Network
(Intersite Call)
Note
・ A maximum of 16 repeaters can be interconnected if Unicast communications are used. If Multicast communications are used,
the number of repeaters that can be interconnected varies depending on the type of network devices, such as a router.
・
A network device which supports Multicast needs to be used in order to use Multicast communications.

Maximum Jitter Buffer Size
Maximum Jitter Buffer Size is the maximum length of time to store the received packet data in the buffer memory
when the receiving repeater receives an Intersite Call.
If voice communications are made by using Intersite Call, the transmitting repeater sends packet data to the network
at certain time intervals. On the other hand, there may be a variation in the intervals for packet data to reach the target
site. Therefore, the receiving repeater starts sending the received packet data after the received packet data is stored
in the buffer memory for once and the length of time configured in Minimum Jitter Buffer Size elapses.
Although the receiving repeater stores the received packet data in the buffer memory, the received packet data is
discarded if the receiving repeater receives the packet data exceeding the value configured in Maximum Jitter Buffer
Size elapses. If the received packet data is discarded, quality of voice communications may be degraded due to audio
interruption, etc.
Smaller buffer size reduces delay of the received audio, but the risk of interruption of the received audio increases.
Larger buffer size reduces the risk of interruption of received audio, but delay of the received audio increases.
This function is available only for doing voice communications. The received packet data is not stored in the buffer
memory if data communications are made.
