Introduction to SIPs and SPAs Chapter 1 SIP and SPA Product Overview Shared Port Adapters The following list describes some of the general characteristics of a SPA: • A SPA is a modular type of port adapter that inserts into a subslot of a compatible SIP carrier card to provide network connectivity and increased interface port density. A SIP can hold one or more SPAs, depending on the SIP type. • Some SPAs provide services rather than network connectivity, and can be inserted into subslots of a compatible SIP. For example, the Cisco WebEx Node for ASR 1000 Series, which provides provides WebEx meeting services, and the DSP SPA which provides voice transcoding and transrating capabilities. • SPAs are available in the following sizes, as shown in Figure 1-1 and Figure 1-2: - Single-height SPA-Inserts into one SIP subslot. - Double-height SPA-Inserts into two single, vertically aligned SIP subslots.

These interfaces can be individually configured using the Cisco IOS command-line interface (CLI).
