DESCRIPTION
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 appropriate zero suppression
and signaling modes.
Several functional blocks exist in the transceiver. The transmit framer/formatter generates appropriate
framing bits, inserts robbed bit signaling, supervises zero suppression, generates alarms, and provides
output clocks useful for data conditioning and decoding. The receive synchronizer establishes frame and
multi-frame boundaries by identifying frame signaling bits, extracts signaling data, reports alarms and
transmission errors, and provides output clocks useful for data conditioning and decoding.
The control block is shared between transmit and receive sides. This block determines the frame, zero
suppression, alarm and signaling formats. User access to the control block is by one of two modes.
In the processor mode, pins 14 through 18 are a micro-processor/ microcontroller-compatible serial port
which can be used for device configuration, control and status monitoring.
In the hardware mode, no offboard processor is required. Pins 14 through 18 are reconfigured into “hard-
wired” select pins. Features such as selection “clear” DS0 channels, insertion of idle code and alteration
of sync algorithm are unavailable in the hardware mode.
