- the PCMCIA cards do not have MIC and SPKR I/Os, unless they are
- specifically built with extra features such as (a) business audio, (b)
- speakerphone, (c) digital simultaneous voice over data, (d) digital
- answering machine.
- In such cases, the side of PCMCIA normally dedicated for RJ-11 cable has a
- different connector which hooks up to an outside pigtail/box allowing to
- plug peripherals such as active quality speakers, external quality MIC,
- gain adjustment on MIC/SPKR, phone line, parallel phone.
-
- PCMCIAs that have scaled-down features, such as D+F would send the audio
- monitor signal via PCMCIA bus interface in digital form (pulse-width
- modulation) to the PC which routes it via its own means to the PC speaker.
-
- if used with Cellular features, it is typical to connect the cellphone via
- a cable to the same connector serving the landline RJ-11 cable hookup, the
- re-routing of signals is automatic. you need a specific cell driver for
- your phone (they are all incompatible) which can load itself automatically
- to the modem memory or user selects it (if he has more than 1 cell phone
- type).
-
- proven and not so new technology.
