Introduction
The Motorola UTA220 terminal adapter connects existing
Data Terminal Equipment (DTE) to the Integrated Services
Digital Network (ISDN). The UTA220 uses the ISDN Basic
Rate Interface which consists of two bearer (B) channels for
data and one delta (D) channel for signaling.
The UTA220 has two DTE port connectors. In addition, the
UTA220 can be ordered with two additional DTE port
connectors for EIA-232 asynchronous use or EIA-366
dialing. Each DTE has access to the 56 kbps/64 kbps ISDN B
channels. The UTA220 functions similarly to two standard
modems in this mode.
