DS2180A T1 Transceiver

The DS2180A is a monolithic CMOS device designed to implement primary rate (1.544 MHz) T-carrier transmission systems. The 193S framing mode is intended to support existing Ft/Fs applications (12 frames/superframe). The 193E framing mode supports the extended superframe format (24 frames/superframe). Clear channel capability is provided by selection of appro.

Features

Single chip DS1 rate transceiver Supports common framing standards
  – 12 frames/superframe “193S”
  – 24 frames/superframe “193E” Three zero suppression modes
  – B7 stuffing
  – B8ZS
  – Transparent Simple serial interface used for configuration, control and status monitoring in “processor” mode =“Hardware” mode requires no host processor; intended for stand-alone applications Selectable 0, 2, 4, 16 state robbed bit signaling modes Allows mix of “clear” and “non-clear” DS0 channels on same DS1 link Alarm generation and detection Receive error detection and counting for transmission performance monitor.
