Figure 2 - Example of V1500 System on a Wide Area Network
It is important that the bandwidth capability of the WAN connections is sufficient to support real-time
performance of the system. The table below can be used as a guideline to determine the bandwidth
requirements at each site. The bandwidth requirements for the V1500CPU WAN connection is the sum of all
remote sites. For example, a typical V1500CDU with the following specifications:
•
128 monitors connected to the video control and titler application cards
•
512 alarms on 2 alarm ports
•
two serial cards, each with 1 keypad and 1 receiver port
would require the following bandwidth (refer to the table below).
Bandwidth requirements for this example =
(# monitors x 200) + (# titling monitors x 1000) + (2 keypad ports x 10,000) + (2 receiver ports X 10,000) + (2 alarm ports x 1000)
= (128x200) + (128x1000) + (2x10,000) + (2x10,000) + (2x1000) = 195,600 bits/sec.

40,000
Each host port.
Your routers (you can use any Cisco router, software revision 12.0 or higher) must support multicasting,
which is the method that the
V1500CDU
s use to identify the main V1500CPU. You do not need to perform this
procedure if you are not on a WAN.
