8-Port OC-12c/STM-4 Multirate POS SPA Overview

The 8-Port OC-12c/STM-4 Multirate POS SPA is a single-height SPA that installs into one SIP subslot.
The SPA with small form-factor pluggable (SFP) optical transceiver modules provides Optical Carrier
Level (OC-n) for SONET and Synchronous Transport Module (STM-n) for SDH network connectivity.
On this SPA, any given port can use either an OC-3 or OC-12 SFP module, so the per-port bandwidth
can be either 155.52 Mbps or 622.08 Mbps, respectively, depending on the customer configuration.
When SFP modules are replaced, the SPA interface retains any previously defined configurations. These
Note
configurations include settings for IP address, clock source, loopback, CRC, and POS flags.
For more information about SPA bandwidth, see the "Bandwidth Oversubscription" topic in this chapter.
For more information about SPAs and their compatibility with SIPs and modular optics, see the "SIP and
SPA Product Overview" chapter in this guide.
