DESCRIPTION
The DS2188 T1/CEPT Jitter Attenuator Chip contains a
128 X 2–bit buffer which, in conjunction with an external
4X crystal, is used to attenuate the incoming jitter pres-
ent in clock and data. The device meets all of the latest
applicable specifications including those outlined in TR
62411 (Accunet* T1.5 Service Description and Interface
Specifications, December 1990), TR–TSY–000170
(Digital Cross–Connect System Requirements and Ob-
jectives, November 1985), and the CCITT Recommen-
dations G.735 and G.742. The DS2188 is compatible
with the DS2180A T1/ISDN Primary Rate Transceiver
and DS2181A CEPT Transceiver and it is the compan-
ion to the DS2187 T1/CEPT Receive Line Interface and
DS2186 T1/CEPT Transmit Line Interface. It can also
be used in conjunction with the DS2190 T1 Network In-
terface Unit.
