Cisco ONS 15454 SDH Product Overview

Card Protection

The G1000-4 card supports three types of standard Cisco GBICs: SX, LX, and

extended reach (ZX). The G1000-4 has four ports rather than two. The additional

ports give the ONS 15454 SDH a practical limit of 40 Gigabit-Ethernet ports per

node. STM-16 is the maximum bandwidth on each G1000-4 card.

Card Protection

The ONS 15454 SDH provides 1:1 and 1:N electrical protection and 1+1 optical

protection. This section describes the protection options and explains protection

switching in the ONS 15454 SDH. Figure 9 shows the CTC tools used to create

card protection groups. For a description of E-series Ethernet protection, see the

“Spanning Tree Protocol” section on page 34.
