Cisco 24-port Channelized Shared Port Adapter

The 24-port Channelized T1/E1 ATM CEoP SPA must be installed in a Cisco 7600 SIP-400 SPA interface processor (SIP) before they can be used in the Cisco 7600 series router. A maximum of four CEoP SPAs can be installed in each SIP, and these SPAs can be different models. You can install the SPA in the SIP before or after you insert the SIP into the router chassis. This allows you to perform online insertion and removal (OIR) operations either by removing individual SPAs from the SIP, or by removing the entire SIP (and its contained SPAs) from the router chassis.
