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.
