Host Accelerated Modem 56K V.92 Chipset — 536EPXX 6.0 Chipset Descriptions The 536EPXX is a Host Accelerated Modem chipset family consisting of a DSP (digital signal processor), and a Silicon Laboratories CODEC/DAA or an Intel Analog Front End (AFE). These chipsets support a variety of applications and need no additional firmware development. The current 536EPXXchipsets are shown in Table 12 “Chipset Composition (PCI & Mini-PCI)” with their corresponding DSP and AFE device part numbers.

Host Accelerated Modem 56K V.92 Chipset — 536EPXX 7.1.5 Videoconferencing (V.80) Support The 536EPXX supports the ITU-V.80 recommendation. This option ensures compatibility with host-based H.324 videoconferencing application software. The 536EPXX chipsets support both transparent and framed submodes of the V.80 synchronous access mode, plus Voice Call First and full-duplex speakerphone. 7.1.6 Loopback Test Modes In all modes except V.

536EPXX — Host Accelerated Modem 56K V.92 Chipset 7.2.7 Call Progress The modem monitors the detection of call-progress tones during call origination and reports them to the DTE. Call-progress tones include dial, busy, ringback, and answer. 7.2.8 Caller ID Caller ID is a service that allows the user to see the caller’s telephone number and name. Caller ID also provides information on call date and time. 7.2.9 International Support The Intel chipsets support international applications.

Host Accelerated Modem 56K V.92 Chipset — 536EPXX Important: 8.3.3 A minimum recovery time of 200µs from D2 to D0 is required before the next function can be accessed. Attempted access sooner than this could result in undefined system behavior. D3cold Switching from main supply outputs to the auxiliary power source requires strict power budgeting of slots, determining those to consume full 3.3Vaux power. A PCI function must draw no more than 20 mA through the 3.
