Description: This object specifies whether the Idle Channel suppression (ICS) is enabled for an AAL2 connection.
What is ccasIfExtVoiceCfgICSEnable?
This enables Idle Channel Suppression (ICS) for an AAL2 (ATM Adaptation Layer 2) voice connection on this DS0 group, letting the gateway stop sending bearer traffic when the channel is idle. ICS specifically saves ATM cell bandwidth on AAL2 trunks by suppressing transmission during silence, which matters on bandwidth-constrained ATM backhaul links where every AAL2 cell carries real cost, unlike TDM trunks where the timeslot is reserved regardless. On an AAL2 trunk backhauling voice over a constrained ATM link, enabling ICS here might cut idle-channel cell traffic to near zero between calls, freeing capacity for other active AAL2 connections sharing that link.
