Description

The SDNS-7050 is an integrated ISDN Terminal Adapter that provides an easy-to-use, high-performance solution for equipment designs requiring access to ISDN service. It features a small size of 2.75" x 1.38" x 0.42" and can directly connect to a host processor through its onboard serial TTL level interface. The module also supports ISDN Basic Rate Interface ETS 300 012 compliance and offers various protocols such as V.110, V.120, PPP, AIMux, and synchronous BONDING.
