DS2175
T1/CEPT Elastic Store
DS2175
022798 1/12
FEATURES
Rate buffer for T1 and CEPT transmission systems
Synchronizes loop–timed and system timed data
streams on frame boundaries
Ideal for T1 (1.544 MHz) to CEPT (2.048 MHz), CEPT
to T1 interfaces
Supports parallel and serial backplanes
Buffer depth is 2 frames
Comprehensive on–chip “slip” control logic
– Slips occur only on frame boundaries
– Outputs report slip occurrences and direction
– Align feature allows buffer to be recentered at
any time
– Buffer depth easily monitored
Compatible with DS2180A T1 and DS2181A CEPT

DESCRIPTION
The DS2175 is a low–power CMOS elastic–store
memory optimized for use in primary rate telecommu-
nications transmission equipment. The device serves
as a synchronizing element between async data
streams and is compatible with North American
(T1–1.544 MHz) and European (CEPT–2.048 MHz)
rate networks. The chip has several flexible operating
modes which eliminate support logic and hardware cur-
rently required to interconnect parallel or serial TDM
backplanes. Application areas include digital trunks,
drop and insert equipment, digital cross–connects
(DACS), private network equipment and PABX–to–
computer interfaces such as DMI and CPI.
