Channel Distribution Function
The RBS searches for Remote OMT link establishment on PCM A
timeslot 23 whenever this timeslot is not used by other functions. The
timeslot is in use when it:
• is configured in the IS (subchannels with bitrate other than 64
kbit/s, TN O&M timeslots, traffic functions)
•
carries the CF link
•
is scanned for the CF link
The remote OMT link will be disconnected if a new IS configuration
configures PCM A timeslot 23 for either:
•
traffic functions
•
subchannels with bitrate other than 64 kbit/s
The remote OMT link uses a protocol based on LAPD. The TEI value
used is 0 and the SAPI value used in the range 20 - 30.
50.4 Operational conditions
50.4.1 Operation and maintenance
Not applicable.
50.4.2 Capabilities
The maximum number of concentration groups is 12 and the
concentration ratios 1:1 to 12:1 (this is only valid for RBS).
The maximum scanning capacity is 24 channels per 1–second interval.
Each TRX handles two links, one OML- and one RSL-link on a
common terrestrial signalling channel.
The CMRU handles one OML link, normally on a signalling channel
shared with a TRX.
When multidrop is used only one PCM (PCM-A) path can be used for
communication towards the BSC.
A maximum of five RBSs can be connected in a linear cascade chain.
