DESCRIPTION
The DS2186 T1/CEPT Transmit Line Interface Chip in-
terfaces user equipment to North American (T1–1.544
MHz) and European (CEPT–2.048 MHz) primary rate
communications networks. The device is compatible
with all types of twisted pair and coax cable found in
such networks.
Key on–chip components include: programmable wave
shaping circuitry, line drivers, remote loopback, and
zero suppression logic. A line–coupling transformer is
the only external component required.
Short loop (DSX–1, 0 to 655 feet) and long loop (CSU; 0
dB, –7.5 dB and –15 dB) pulse templates found in T1
applications are supported. Appropriate CCITT recom-
mendations are met in the CEPT mode.
Application areas include DACS, CSU, CPE, channel
banks, and PABX–to–computer interfaces such as DMI
and CPI. The DS2186 supports ISDN–PRI (Primary
Rate Interface) specifications.
