1-Port and 3-Port Clear Channel OC-3 ATM SPA Overview
Note If you oversubscribe the SIP, and the SPA subslot is locked in the failed state, refer to the
“Troubleshooting the SPA” section on page 7-2 for instructions on how to enable the SPA.
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.
The following sections describe the 1-Port and 3-Port Clear Channel OC-3 ATM SPA:

1-Port and 3-Port Clear Channel OC-3 ATM SPA LEDs
The 1-Port and 3-Port Clear Channel OC-3 ATM SPA has three types of LEDs. There are two LEDs for
each port on the SPA, and one STATUS LED. Figure 3-2 sho
ws an example of these LEDs on a 3-Port
Clear Channel OC-3 ATM SPA.
