DS-30X Speech Links are used to carry speech and some signalling on Norstar Modular platforms.

== Physical ==
* Four wires (arrows are controller <-> card) <ref name="ds30xphy">[[File:NN43001-311_02.09_Installation_CirCrdFundamentals.pdf|page=25|25px]] Circuit Card Fundamentals, Page 25</ref>
** Tx PCM →
** Rx PCM ←
** 5.12MHz Clock →
** 1kHz Frame Sync →

== Electrical ==
* Signal levels unknown
* Isolation unknown

== Logical ==
* Clocked at 2.56MHz (half the 5.12MHz clock received from the controller)
* Carries 32 channels of PCM voice data
* Each channel consists of a 10-bit word
** 8 bits of voice data (called a "timeslot")
** 1 bit of signalling data
** 1 bit indicating "data valid"
* Signalling data is sent in 24-bit words, one bit at a time in each channel.
** Sent in both directions, one on Tx PCM and one on Rx PCM
