Congestion Control

ATM encapsulations provide congestion control via EPD thresholds on a per logical
interface basis. For Circuit Emulation PICs, the EPD number specifies the number
of packets (or frames or cell bundles).

QoS/Shaping

Unspecified bit rate (UBR) is supported.

Configuring the PIC Type

To configure Circuit Emulation PICs, you must specify the
pic-type

Configuring Layer 2 Circuit and Layer 2 VPN Pseudowires

ATM Layer 2 circuit and Layer 2 VPN pseudowires are configured using the same
syntax described for ATM2 PICs:

Supported Interface Configurations

With 12-port Channelized T1/E1 Circuit Emulation PICs, ATM supports T1 and E1
interfaces:
