The CH24606, a V.22bis
modem module (2400 bits per second), is the first Cermetek modem designed to comply with UL 60601-1 requirements for medical equipment safety.
The Si2457, Si2434, Si2415 and Si2404 support V.90, V.34, V.32bis and V.22bis
respectively over the Public Switched Telephone Network (PSTN) in both synchronous and asynchronous data formats.
It combines all the controller (DTE) and data pump functions necessary to implement an intelligent V.22bis
The MT1932BL provides the higher data rates while maintaining compatibility with lower-speed modems based on V.32bis, V.32, V.22bis
and other common modulation standards.
To provide the required fallback modes for V.32bis schemes and to allow the flexibility of "old-to-new" system migration in OEM products, the CMX869 offers V.32bis: V.32 and V.22bis
(QAM), V.22 (DPSK) and V.23, V.21 and Bell equivalent (FSK) modulation schemes.
Oki Semiconductor, a technology partner for the new era of digital communications and convergence, and Innovada, a provider of device to device communications, have unveiled a V.22bis
embedded modem solution for Oki's advantage microcontroller family of general purpose MCU products.
Both comply with CCITT V.21, V.22 and V.22bis
standards for 300/1200/2400 baud operation, and with Bell 103/212A standards.
The CH1788 V.22bis
full function modem is a surface-mount device configured in a 68-pin PLCC format package, incorporating an FCC-approved telephone interface.
* Standards support including CCITT V.22bis
, V.22, V.23, V.21 and Bell 212A and 103.
It features no interactive display, instant screen response, and compatibility with v.22bis
, Bell 212A, and Bell 103 modems.
