Configuring Circuit Emulation Services
This chapter describes circuit emulation services (CES) and how to configure the CES T1/E1 port
adapters in the Catalyst8540 MSR, Catalyst 8510 MSR, and LightStream 1010 ATM switch routers.
You can use CES T1/E1 port adapters for links that require constant bit rate (CBR) services.
Note This chapter provides advanced configuration instructions for the Catalyst8540 MSR,
Catalyst 8510MSR, and LightStream 1010 ATM switch routers. For an overview of CES applications
and operation, refer to the Guide to ATM Technology. For complete descriptions of the commands
mentioned in this chapter, refer to the ATMSwitch Router Command Reference publicatio n. For
hardware installation and cabling instructions, refer to the ATMand Layer 3 Port Adapter and Interface
Module Installation Guide.
