TEW4994-1规格书详情
TEW4994 is designed to be used either as a transmit or a receive transformer in the ISDN primary access network, interfacing SIEMENS PEB2235 and PEB2236 to a 75, 100 or 120 ohm line.
When in transmit mode, connect the two primary windings in parallel, pin 1 to 2 and pin 5 to 6.
When in receive mode, connect the two primary windings in series, pin 5 to pin 2, thus forming a center tap at pin 5/2.
Typical applications are:
• Primary rate ISDN network nodes.
• PBX or computer to T1/CEPT Digital trunks.
• TDM Multiplexers.
