Description
The XEISDNU integrated ISDN Terminal Adapter is a unique component level solution for high speed, stand-alone and embedded equipment applications needing access to ISDN service. The module can directly connect to a host computer through its on-board EIA-232E interface and link to the ISDN subscriber line U interface with its integrated NT1.

FEATUREs
• Small size: 2.75" x 1.38" x 0.42"
• On-board Motorola MC68302 Integrated Multiprotocol Processor with RISC controller for high speed operations; also included on-board: 128K x 16 SRAM, 256K x 16 Flash Memory and 8K x 8 EEPROM
• ISDN line U interface (integrated NT1) with 2B1Q encoding (ANSI T1.601) for North American usage. V.120 data rate adaptation protocol and point to point protocol (PPP)
• ISDN control program allows connection with AT&T 5ESS, Northern Telecom DMS 100 and National ISDN-1 central office switches
• Standard EIA-232E, ITU V.24 serial interface, 300 to 115,200 bps asynchronous and 1200 to 64,000 bps synchronous data rate
• Menu-driven and stored configurations
• Control signal outputs to interface with XEISDNP Analog Telephone (POTS) Equipment Interface module
• On-board ISDN Monitor supports user program downloading and system debugging
• Jumper configurable memory addressing allows change from Development mode (using ISDN Monitor) to Application mode (using either a built-in ISDN control program or a user developed program)
• ISP (In System Programmable) Flash Memory capability for future function up-grading
