CEPT Primary Rate Transceiver
DS2181A
022798 1/32
FEATURES
Single–chip primary rate transceiver meets CCITT
standards G.704, G.706 and G.732
Supports new CRC4-based framing standards and
CAS and CCS signalling standards
Simple serial interface used for device configuration
and control in processor mode
Hardware mode requires no host processor;
intended for stand-alone applications
Comprehensive, on-chip alarm generation, alarm
detection, and error logging logic
Shares footprint with DS2180A T1 Transceiver
Companion to DS2175 T1/CEPT Elastic Store,
DS2186 Transmit Line Interface, DS2187 Receive
Line Interface, and DS2188 Jitter Attenuator
5V supply; low-power CMOS technology
DESCRIPTION
The DS2181A is designed for use in CEPT networks
and supports all logical requirements of CCITT Red
Book Recommendations G.704, G.706 and G.732. The
transmit side generates framing patterns and CRC4
codes, formats outgoing channel and signalling data,
and produces network alarm codes when enabled. The
receive side decodes the incoming data and esta-
blishes frame, CAS multiframe, and CRC4 multiframe
alignments. Once synchronized, the device extracts
channel, signalling, and alarm data.
A serial port allows access to 14 on-chip control and sta-
tus registers in the processor mode. In this mode, a host
processor controls features such as error logging, per-
channel code manipulation, and alteration of the receive
synchronizer algorithm.
The hardware mode is intended for preliminary system
prototyping and/or retrofitting into existing systems.
This mode requires no host processor and disables
special features available in the processor mode.
