channel support
Each nanoBTS supports a single TRX and can act as a
standalone BTS
Up to 4 nanoBTS can also be connected to act as a Multi-TRX
BTS
Single TRX or C0 of MultiTRX
TS0 = full BCCH, Combined BCCH or Combined BCCH with
CBCH
TS1-7 = TCH(full or half rate), PDCH or Dynamic PDCH/TCH
Additionally TS1 may be SDCCH/8 + SACCH/C8 (with optional
CBCH)
Multi TRX (non C0)
TS0-7 = TCH(full or half rate)
Additionally TS1 may be SDCCH/8 + SACCH/C8
Internal clock frequency
Better than 100ppb as per GSM 05.10 pico
