ISDN Echocancellation Circuit
4-Channel for 4B3T Line Code
The ISDN 4B3T Echocancellation
Circuit 4-channel (IEC4-T) is an
optimized chipset featuring 4
times ISDN basic rate access. It
consists of the analog frontend
PEB 24902 and the digital front-
end PEB 24901. This chipset
fulfills all relevant standards.
Potential Applications
E Central oNce digital linecards
I:I Access networks linecards
Features
I: Two chip solution featuring 4
channel full duplex data trans-
mission and reception over
two-wire metallic subscriber
loops providing ISDN basic rate
access at 144 kbit/s
El Fully compliant to:
- FTZ guideline 1TR 220
- ETSI ETR 080 (1996)
- Recommendation ITU-T G.961
n 4B3T block code at 120 kHz
symbol rate
I: LT mode for linecards
Auxiliary functions like relay
drivers and status inputs are
provided. An IOM®-2 interface is
used to provide data and control
access to the PEB 24901 thus
easing the PCB layout. The
IEC4-T chipset is pin compatible
to the lEC4-Q chipset. A sophisti-
n Low power consumption
El KOMO-i interface for stand alone
mode featuring different clock
speeds
El 1 kbit/s maintenance channel
Integrated wake-up unit
ta Monitoring of transmission
errors
I: Maximum loop length:
- 4.2 km with 0.4 mm wire
- 8.0 km with 0.6 mm wire
Absorption of up to 18 us peak
to peak phase jitter
Switching of analog testloops
Activation and deactivation
Masterclock generation by PLL
Automatic polarity adaption
Automatic gain control
cated powermanagement system
allows to reduce the application's
powerconsumption to a minimum.
Siemens Semiconductor offers
also a broad range of other
telecom ICs making it easy to
integrate the IEC4-T into a com-
plete system solution.
I: Adaptive echocancellation
El Adaptive equalization
n 4 drivers per channel to switch
relays or a power controller
EI 2 status inputs per channel
I: Extended temperature range
