1-Port and 3-Port Clear Channel OC-3 ATM SPA Overview
The 1-Port and 3-Port Clear Channel OC-3 ATM SPA is a single-height SPA that installs into one SIP
subslot. The Clear Channel OC-3 ATM 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.
For more information about SPA bandwidth, see the "Bandwidth Oversubscription" section in this
chapter.
