Interfacing to the Fractional
abstract: this application note provides an example fractional t1 and e1 circuit design using dallas semiconductor/maxim communications products t1/e1 single chip transceivers (scts) and t1/e1 framers.
introductionthis application note shows a looped-timed application where a dallas framer or single-chip transceiver (sct) is configured for a fractional t1/e1 interface.
this application note applies to the following products:
t1 framers e1 framers t1 scts e1 scts t1/e1 scts

ds26521
ds26519
ds26518
general configurationit is common for a t1/e1 carrier subscriber to not have the full t1/e1 rate of service, but a fractional t1 or e1 service, since the full bandwidth may not be needed or affordable. the circuit shown in figure 1 shows an example of a fractional t1/e1 circuit design, where the application is looped-timed and connected to a v.35/rs-449/s530 interface. in this figure, the transmit and receive ft1/e1 streams occupy the same time slots. the ds2175 is our t1/cept elastic store ic and the xr-t8000 is the exar clock synchronizer/adaptor for communications ic. the idle registers on the dallas framer/sct can be used to fill unused channels, and the used channels do not need to be contiguous. rchblk can be used with tchblk to allow up to three additional ft1/e1 ports. reset should be activated after all the clocks are stable.

conclusionthis application note has shown how to design our framers/scts for fractional t1/e1 in a loop-timed application.
