Description
The XEISDNB integrated ISDN Terminal Adapter offers an easy to use, high performance, component-level solution for equipment designs needing access to ISDN service. The module can directly connect to a host processor through its on-board serial TTL level interface and link to the ISDN subscriber line U interface with its integrated NT1.

FEATUREs
