Multipoint Dialing Speed Table

© Polycom, Inc. 2002
When there are more than two parties participating in a video call,
it is called a multipoint call. You can have up to four parties
participating in a call with the ViewStation FX or the VS4000.
If you have a PRI or BRI network interface, you can place multipoint
calls over a PRI or BRI line or over IP (H.323) on the LAN. If you
have a V.35/RS-449 network interface, you can place multipoint
calls only over IP on the LAN.
The following table shows the maximum allowable dialing speeds
according to the number of sites in a call. All parties in a multipoint
call must be connected at the same speed.
