+%description
+In GSM, A-bis is a BSS-internal interface link between the BTS and
+BSC. This interface allows control of the radio equipment and radio
+frequency allocation in the BTS.

+%description -n libosmoabis6
+In the GSM system architecture, A-bis is a Base Station
+System-internal interface linking the Base Transceiver Stations (BTS)
+and Base Station Controller (BSC). This interface allows control of
+the radio equipment and radio frequency allocation in the BTS.
+
+This library contains common/shared code regarding this A-bis
+interface. It also implements drivers for mISDN and DAHDI-based E1
+cards, as well as some A-bis/IP dialects.

+
+%description -n libosmotrau2
+This library implements the Transcoder and Rate Adaptation Unit (TRAU) for
+GSM systems.
+The TRAU enables the use of lower rates (32, 16 or 8 kbps) over the
+A-bis interface instead of the 64 kbps ISDN rate for which the Mobile
+Switching Center (MSC) is designed.
