8-Port OC-3/STM-1 POS SPA Overview
The 8-Port OC-3/STM-1 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 an OC-3 SFP module, so the per-port bandwidth can be 155.52 Mbps.
Note
When SFP modules are replaced, the SPA interface retains any previously defined configurations. These
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.
The following sections describe the 8-Port OC-3/STM-1 POS SPA:
