APPLICATION NOTE 306
DS2141A, DS2143 Three Channel Drop and Insert
Abstract: Application Note 306 provides the design requirements for implementing a three channel drop and
insert application using the Dallas Semiconductor/Maxim DS2141A T1 framer or DS2143 E1 framer.
Notes:
1. A "looped-timed" application is shown.
2. This application assumes the dropped channels occupy the same timeslots as the inserted channels.
3. The idle registers in the DS1241A/43/51/53 can be used to fill unused (if any) channels.
4. The used channels do not need to be contiguous nor do they need to b……
