The 40-795/796 Daisy Chain Switching Module is designed
for telecom test applications. It allows production or
verification testing of SONET/SDH transmission multiplexers

balanced lines. The following modules are available:
• 8 Tributary Daisy Chain Switch Balanced Module
(40-795-001)
• 16 Tributary Daisy Chain Switch Balanced Module
(40-796-001)
Multiple modules can be cascaded together to form very large
systems, for example a 7-slot PXI chassis can contain a 112
tributary switching system and an 18-slot PXI chassis can
contain up to 272 tributaries.
The Daisy Chain Switching Module allows traffic to be
sequentially Daisy-Chained through all tributaries (or any
selection of tributaries) and modules can be cascaded to test
any number of tributaries. Multiplexers are provided to allow
transmit or receive instrumentation to be connected to any
tributary. This allows specific testing of a port, for example for
the measurement of pulse shape distortion or return loss.

SDH/SONET Tributary Testing is a very specialised
area, please contact Pickering Interfaces for additional
application information and to discuss your exact
requirements.
Pickering Interfaces also have SDH/SONET switching
solutions in our System 30 (VXI) and system 20 (IEEE-
488) switching systems.
