Gb congestion does not prevent a TBF establishment or PDCH allocation.
Gb congestion will lead to throughput reduction thanks to flow control mechanisms in SGSN and PCU (MFS)
PDCH allocation failure can be due to
Abis congestion
Ater-PS congestion
radio timeslot congestion (too many TCH, or too many PDCH accordingly to the parameter settings)
PCU congestion (= GPU/DSP congestion in ALU)
Interference
Coverage…
