3Com (3C0504222-00) Expansion Module - The advanced design of 3Com's 96-port Total Control 1000 DSP multi-span card set enables multiple modem sessions, ISDN processing, voice-codecs, and PPP co-processing on a single DSP - delivering high-level functionality in a small space. The card set can process three E1 or four T1 spans and 96 channels per card within just one platform slot.??In a fully populated Total Control 1000 system, the DSP card set can process up to 672 calls via T1 and up to 630 calls via E1. Unlike a simple modem card, the DSP card set features a fully reprogrammable DSP engine that lets administrators reconfigure the system to implement new technologies and applications such as VoIP. The card set supports a full range of trunk and communications standards, including V.Everything and many variations of CAS/PRI and NFAS/SS7.
