What bandwidth and provisioning issues are recommended?
Local LAN Bandwidth: • Minimum 10 Mbps, 100 Mbps is preferred. Because some routers do NOT auto negotiate reliably, we recommend NOT using the AUTO setting, instead select 10 or 100 fixed. Codecs should also be fixed 10 or 100. • Full duplex from the codec to the Access New Jersey edge router minimizes the effects of latency and jitter and is preferred. Codecs should also be fixed to full duplex. Bandwidth and provisioning to Access New Jersey Video Portal: • To allow for 384 Kbps calls, as an example, you need bandwidth plus overhead. One H.323 connection at 384K plus overhead for call setup and signaling is about 512K. One T1 can never have more than one H.323 call across it. • In some cases it may be better to have a central High School be the main “hub” in the district and all the others sites to aggregate here. • Communicate your needs to Video Portal staff for recommendations. • To have a circuit provisioned between school or school district to the Video Portal’s backbone, please
