CE-1000-4 Ethernet Operation
Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms
do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration.
Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's
path protection feature, which may be used in any topological network configuration. Cisco does not
recommend using its path protection feature in any particular topological network configuration.
This chapter describes the operation of the CE-1000-4 (Carrier Ethernet) card supported on the
Cisco ONS 15454 and Cisco ONS 15454 SDH. A CE-1000-4 card installed in an ONS 15454 SONET
is restricted to SONET operation, and a CE-1000-4 card installed in an ONS 15454 SDH is restricted to
SDH operation.
Use Cisco Transport Controller (CTC) or Transaction Language One (TL1) to provision the CE-1000-4
card. Cisco IOS is not supported on the CE-1000-4 card.
For Ethernet card specifications, refer to the Cisco ONS 15454 Reference Manual or the
Cisco ONS 15454 SDH Reference Manual. For step-by-step Ethernet card circuit configuration
procedures, refer to the Cisco ONS 15454 Procedure Guide or the Cisco ONS 15454 SDH
Procedure Guide. Refer to the Cisco ONS SONET TL1 Command Guide or the Cisco ONS SDH Command
Guide for TL1 provisioning commands.

CE-1000-4 Overview
The CE-1000-4 is a Layer 1 mapper card with four Gigabit Ethernet ports. It maps each port to a unique
SONET/SDH circuit in a point-to-point configuration.
Figure 25-1 illustrates a sample CE-1000-4
application. In this example, data traffic from the Gigabit Ethernet port of a switch travels across the
point-to-point circuit to the Gigabit Ethernet port of another switch.
