TEW5376 Datasheet, PDF (1/1 Pages) Filtran LTD – CEPT/T1 Input/Output Transformer

CEPT/T1
Input/Output Transformer
TEW5376 is designed to be used
either as a transmit or as a
receive transformer in the ISDN
primary rate access network, for
the following devices.
Siemens
PEB2235
PEB2236
SGS-THOMSON STLC5432
Complies with ANSI T1.408 and
CCITT I.431, with regards to
Longitudinal Balance and with
T1.408 and G.703 for the return
Loss.
When in transmit mode, connect
the two primary windings in
parallel, pins 1 to 3 and 2 -4.
When in receive mode, connect
the two primary windings in
seriesp, pin 2 to pin 3.
Typical applications are:
• Primary rate ISDN network
nodes.
• PBX or computer to
T1/CEPT Digital Trunks.
• TDM Multiplexers.
