Specify a HSSI

To specify a HSSI and enter interface configuration mode, perform the following tasks in global
configuration mode:
Task
Begin interface configuration.

Specify HSSI Encapsulation

The HSSI supports the serial encapsulation methods, except for X.25-based encapsulations. The default
method is HDLC. You can define the encapsulation method by performing the following task in interface
configuration mode:
Task
Configure HSSI encapsulation.
For information about PPP, see the "Configure SLIP and PPP" chapter of the Cisco IOS Release 11.3
Access Services Configuration Guide and the "Configure PPP for Wide-Area Networking" chapter of
the Cisco IOS Release 11.3 Wide-Area Networking Configuration Guide.

Invoke ATM on a HSSI Line

If you have an ATM DSU, you can invoke ATM over a HSSI line by mapping an ATM virtual path
identifier (VPI) and virtual channel identifier (VCI) to a DXI frame address. ATM-DXI encapsulation
defines a data exchange interface that allows a DTE (such as a router) and a DCE (such as an ATM DSU)
to cooperate to provide a User-Network Interface (UNI) for ATM networks.
