2.2 DESCRIPTION
The Model 1080A Series Universal Short Range Modem operates 2-
wire (half duplex) or 4-wire (full or half duplex), in synchronous or asyn-
chronous modes, over unconditioned telephone lines. The Model 1080A
supports bit rates up to 57.6 kbps. The 1080A operates in synchronous
mode between the local and remote modems; when connected to an
asynchronous RS-232 device, the Model 1080A Series SRM converts
the asynchronous data to synchronous data.
The Model 1080A Series has several features to enhance overall perfor-
mance: automatic equalization, automatic gain control, anti-streaming
timer, transformer isolation to guard against data loss due to ground
potential differences, and Silicon Avalanche Diode surge protection to
guard against data line transients.
