T1 CSU/DSU ASE is
deployed on a T1 access line at the demarcation point
between the provider network and customer premises.
It supports full and fractional (FT1) T1 networks and
provides connectivity through V.35 and additional
digital cross connect signal (DSX-1) interfaces.
The ASE supports Multi-Protocol software for deploy-
ment in standard frame relay or HDLC networks and
IP Transport software for deployment in frame relay or
HDLC-based networks that use IP switching.
In addition to performing standard CSU/DSU
functions—such as BER tests, loopbacks, and power
failure detection—the ASE is capable of inserting
management traffi c.
The ASE’s “drop-and-insert” feature provides a
secondary DSX-1 port that can connect to a Private
Branch Exchange at a customer’s site. T1 Timeslots
can be segmented for a PBX on the same circuit car-
rying data traffi c (see fi gure).
