E-Series and G-Series 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 covers the operation of the E-Series and G-Series Ethernet cards. E-Series and G-Series
cards are supported on the ONS 15454, ONS 15454 SDH, and ONS 15327. 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, Cisco ONS 15454
SDH Reference Manual, or Cisco ONS 15327 Reference Manual. For step-by-step Ethernet card circuit
configuration procedures, refer to the Cisco ONS 15454 Procedure Guide, Cisco ONS 15454 SDH
Procedure Guide, or the Cisco ONS 15327 Procedure Guide. Refer to the Cisco ONS SONET TL1
Command Guide or Cisco ONS SDH TL1 Command Guide for TL1 provisioning commands.

G-Series Application
The G-Series cards reliably transport Ethernet and IP data across a SONET/SDH backbone. The
G-Series cards on the 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 card on the ONS 15327 maps two Gigabit Ethernet
ports. 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:
