Six-Port MICA Modules and Carrier Cards

The 6-port MICA modules can send data at up to 56 kbps and receive data at up to

33.6 kbps. Connections at 56 kbps start as analog, are converted to digital, and are not

converted back to analog at the service provider. Because one conversion (from digital to

analog) is omitted, speeds of up to 56 kbps are possible. However, the actual speed that you

can achieve with the module depends on the condition of your local telephone network.

The 6-port MICA modules and carrier cards support the following protocol and modulation

standards:

• Rockwell K56ﬂex at 56000 to 32000 in 2000 bps increments

• Software upgradeable to ITU V.90 56K

• ITU-T V.34 Annex 12 at 33600 and 31200 bps

• ITU-T V.34 at 28800, 26400, 24000, 21600, 19200, 16800, 14400, 12000, 9600, 7200,

4800, and 2400 bps

• ITU-T V.32terbo at 19,200, 16,800, 14400, 12000, 9600, 7200, and 4800 bps

• ITU-T V.32bis at 14400, 12000, 9600, 7200, and 4800 bps

• ITU-T V.32 at 9600 and 4800 bps

• ITU-T V.23 1200/75 bps (back channel)

• ITU-T V.22bis at 2400 and 1200 bps

• ITU-T V.22 at 1200 bps

• ITU-T V.21 at 300 bps

• Bell 212A at 1200 bps

• Bell 103A at 300 bps

• ITU-T V.42 error correction (including MNP 2-4 and LAPM)

• ITU-T V.42bis (1K nodes) and MNP 5 data compression
