Guralp Systems CMG-DCM build <10,000 - Manual (Page 18)

Acquisition Modules and Platinum Firmware Equipment Overview
The CMG-NAM can also act as a data server to remote clients supporting GCF
(SCREAM server), EARTHWORM (via scream2ew), ANTELOPE (via
Guralp2orb), CD1.0/CD1.1 and SEEDLINK.
It is also possible to use data filtering (by channel name and/or sample rate) in
such a way that, should it become necessary to use the higher-cost link, only
high priority data (e.g. samples resulting from an activated trigger) are sent
across this link while lower priority data are enqueued until the low-cost link
becomes available again.
