This document addresses the major differences and compatibility issues between the Cisco ONS 15454 and
the Cisco ONS 15327 Synchronous Optical Network (SONET) Add/Drop Multiplexer (ADM) Network
Elements (NE). This document encompasses software releases up to Release 4.0 on the ONS 15454 and
Release 4.0 on the ONS 15327.

The ONS 15327 is a small, cost−effective device for managed services and high−speed bandwidth
aggregation for multiple services when the full capabilities of the ONS 15454 are not required. It supports
DS1, DS3, Optical Carrier (OC)−3 (R3.3 and higher), OC−12, OC−48, Ethernet 10/100, and G1000(R4.0)
services, and you can deploy in linear, Unidirectional Path Switched Ring (UPSR), Bi−direction line swich
(BLSR R3.3) or Path Protected Mesh Network (PPMN) configurations. You may deploy the ONS 15327
along with the ONS 15454 in any of the ONS 15327's supported configurations. Figure 1 shows the ONS
15327 and the ONS 15454:
