Chapter 23 E-Series And G-Series Ethernet Operation; G-Series Application - Cisco ONS 15454 SDH Configuration Manual

E-Series and G-Series Ethernet Operation
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms
Note
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 covers the operation of the E-Series and G-Series Ethernet cards. E-Series and G-Series
cards are supported on the ONS 15454 and ONS 15454 SDH. Provisioning is done through Cisco
Transport Controller (CTC) or Transaction Language One (TL1). Cisco IOS is not supported on the
E-Series or G-Series cards.
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. For TL1 provisioning commands, refer to the Cisco ONS SONET TL1 Command Guide or the
Cisco ONS 15454 SDH and Cisco ONS 15600 SDH TL1 Command Guide.

G-Series Application

The G-Series cards reliably transport Ethernet and IP data across a SONET/SDH backbone. The
G-Series cards on the ONS 15454 and ONS 15454 SDH map up to four Gigabit Ethernet ports onto a
SONET/SDH transport network and provide scalable and provisionable transport bandwidth at signal
levels up to STS-48c/VC4-16 per card. The G-Series cards provide line rate forwarding for all Ethernet
frames (unicast, multicast, and broadcast) and can be configured to support Jumbo frames (defined as a
maximum of 10,000 bytes). The G-Series cards incorporate features optimized for carrier-class
applications such as:
