48 Transmission Interface Handling
DS1 1544 kbit/s
This function specification covers RBS functions for layer 1
communications on A-bis.
The function Layer 1 Termination terminates a 1544 kbit/s DS1 PCM
line.
The function Supervision of Transmission faults detects faults in the
transmission interface.
The function Supervision of Transmission Quality monitors the quality
of the transmission.

48.2 Concepts
CMRU Central Main Replaceble Unit. An RBS
has exactly one CMRU. In the RBS 2000
hardware architecture, the DXU is the
CMRU
Main RU Contains one or more processors, to which
software can be downloaded from the
BSC. A Main RU is either central or
distributed, see above. A Main RU may
or may not have a direct signalling link to
the BSC.
RU Replaceble Unit. An RU is the smallest
unit that can be handled on site or in a
repair center and of which information can
be retrieved via OMT or BSC.
Extended superframe format The content and structure of the F-bit is
described in the figure below. This figure
is included to ease the understanding of
the functions Layer 1 Termination and
Supervision of Transmission Faults.
