2-Port and 4-Port OC-3c/STM-1 POS SPA Overview
The 2-Port and 4-Port OC-3c/STM-1 POS SPA is a single-height SPA that installs into one SIP subslot.
The 2-Port and 4-Port OC-3c/STM-1 POS SPA with small form-factor pluggable (SFP) optical
transceiver modules provides SONET and SDH network connectivity with a per-port bandwidth of
155.52 Mbps. The 2-Port and 4-Port OC-3c/STM-1 POS SPA operates at quarter rate.
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 SPAs and their compatibility with SIPs and modular optics, see the
and SPA Compatibility" section on page
