QUAD T1/E1 CONNECTION Figure 14C
16 Port T1 or E1 with 256 HDLC Channel Support
Figure 14D shows an application where 16 T1 ports are interfaced to a single DS3134. In this
application, the T1 lines can be either clear channel or channelized. The DS21Q552 Quad T1 Transceiver
performs the line interface function and frames to the T1 line. To convert this application to an E1
design, the DS21Q552 is replaced with the DS21Q554 Quad E1 Transceiver, which is pin-for-pin
compatible. The DS21Q552 and DS21Q554 devices also are available in 3.3V versions (DS21Q352 and
DS21Q354 respectively).
