Release Information

Statement introduced in Junos OS Release 8.2.

Description

This statement is used only in conjunction with J Series Services Routers that support voice over IP with the TGM550. For Fast Ethernet and Gigabit Ethernet interfaces, ISDN BRI interfaces, and serial interfaces with PPP or Frame Relay encapsulation, configure dynamic call admission control (CAC). Dynamic CAC provides enhanced control over WAN bandwidth. When dynamic CAC is configured on an interface responsible for providing call bandwidth, the TGM550 informs the Media Gateway Controller (MGC) of the bandwidth limit available for voice packets on the interface and requests that the MGC block new calls when the bandwidth is exhausted.

Dynamic CAC must be configured on each J Series Services Router interface responsible for providing call bandwidth.

The remaining statements are explained separately.
