The Xecom XE1201/1203 MOSART should more than fit your requirements.
The listed features of this device are:
- small size: 2.25"x 1.0" x 0.5" -Full Bell 212A & 103 compatible
- 8251A software compatible -DTMF or pulse dialing
- Call Progress monitoring -DTMF reception and decoding
- Software controlled audio interface for voice communication or
acoustic coupling
- FCC registered -Parity generation & checking
- Synch byte generation/detection -Extensive inbuilt diagnostics
- +/- 5VDC power only -Telephone-line diagnostics
- Voice synthesis option (1203) -Synch/asynch operation.
- Connects directly to phone line
Xecom also has a development kit which includes a board to fit the IBM-PC
slot.
The device was featured as a Circuit Cellar Project in BYTE a couple of
years ago.
