The Quad ISDN 2B1Q Echocanceller Digital Front End (DFE-Q) is the digital part of an
optimized two-chip solution featuring 4x ISDN basic rate access and IDSL access at 144
kbit/s. The PEF 24911 is designed to provide in conjunction with the Quad ISDN
Echocanceller Analog Front End (PEF 24902 V2.1) full duplex data transmission at the
U-reference point according to ANSI T1.601 (1998), ETSI TS 102 080 (1998) and ITU-
T G.961 standards.
The DFE-Q 2nd generation has been completely reengineered to guarantee the
availability of the well proved DFE-Q/AFE solution over the year 2000. The PEF 24911
V2.1 is downwards pin compatible and functionally equivalent to the DFE-Q V1.x. Thus,
line card manufacturers can make use of the most advanced process technology without
the need to change their current design (besides the changeover to 3.3 V power supply).
No software changes are required if the DFE-Q V2.1 is deployed in existing DFE-Q V1.x
solutions. Some new features are provided such as free programmable filtering options
for the maintenance bits (M1-6) and enhanced monitoring and test functions. The data
rate is programmable from 1 Mbit/s to 4 Mbit/s.
Figure 1
The output and input pins are throughout 5 V TTL compatible although the PEF 24911
is processed in advanced 3.3 V CMOS technology. A power down state with very low
power consumption is featured.
The PEF 24911 comes in a P-MQFP-64 package.
