Mechanical Interrupts - Interrupts can be individually enabled by STD Bus mechanical dimensions: 4.5” x 6.5” software for any or all of the following conditions: Received Data Available, Transmitter Holding Register Connectors Empty, Receiver Line Status and Modem Status. An Telephone: RJ-11C interrupt request can be jumper selected to one of the Frontplane interrupt: 10-pin on 0.100 inch grid four STD Bus backplane INTRQ lines or over the front Jumpers: 0.025” square posts plane of the board. Environmental Telephone Line Interface - The connection to the Operating Temperature: 0 to +60°C phone line is through a RJ-11C jack. An onboard FCC Part 68 registered DAA provides the required isolation ORDERING INFORMATION and protection for connection to dial-up lines. MCM-33.6M 33600 bps STD Bus Fax/Modem Non-volatile RAM - A 256 x 8 NVRAM is on the board LPM-33.6M CMOS STD Bus Fax/Modem which allows storage of two user configurations and MCM-14.4M 14400 bps STD Bus Fax/Modem four 35-digit speed-dial strings. LPM-14.4M CMOS STD Bus Fax/Modem Auto Dialing - Both pulse and tone dialing are support- ed. DTMF dialing using DTMF tone pairs is supported in accordance with ITU-T Q.23. Pulse dialing is sup- ported in accordance with EIA/TIA-496-A. Auto Answer - When an incoming ring is detected, the board goes Off-Hook and returns an answer tone to the remote caller. If a carrier is not detected, it terminates the call and goes On-Hook. Software - The LPM/MCM-33.6M/14.4M supports the enhanced “AT” Command Set and is compatible with many PC communications software packages. Self Test - The board provides analog loopback, digital loopback, and remote digital loopback functions for testing purposes. 715 Stadium Drive  Arlington, Texas 76011  (817) 274-7553  http://www.winsystems.com
