AUSM cards are service modules that provide ATM Network-to-Network Interfaces (NNIs)/UNIs that
operate at T1 or E1 rates so that ATM UNI user devices can transmit and receive traffic.
Consistent with the Cisco intelligent quality of service (QoS) management features, AUSM cards
support per-virtual circuit (VC) queuing on ingress and multiple class-of-service queues on egress.
AUSM/Bs fully support continuous bit rate (CBR), variable bit rate (VBR), unspecified bit rate (UBR),
and available bit rate (ABR) service classes.
When the AUSM is combined with a back card, a card set is created.

The AUSM cards also support ATM Forum-compliant inverse multiplexing over ATM (IMA) 1.0. This
capability enables multiple T1 or E1 lines to be grouped into a single high-speed ATM port. This n x T1
and n x E1 capability fills the gap between T1/E1 and T3/E3, providing bandwidth up to 12 Mbps
(n x T1) or 16 Mbps (n x E1), without requiring a T3/E3 circuit.
