New AS7-D equal to SWPRO-C
new AS7-D unit offers:
- 512 HDLC channels (2x that of AS7-C), 8xmore memory, data processing performance is
estimated to be ~1.4x that of AS7-C- an interface to OMC (X.25), then it is installed
in OMU,
- capability to co-exist in the same cartridge with AS7-C
- capability to act as a new control unit forGSWB
- the relevant FU is then called SWPRO-C and AS7-D is installed in MCMU
- SWPRO-C will replace SWCOP-A used so far
- due to the need to serve 1000 additional TRX anew control unit is mandatory
- SWPRO-C allows to control higher amount ofconnections and generates less load to theMCMU CPU in comparison to SWCOP-A

– 480 LAPD@64 – 4 SS7@128
– 480 LAPD@64 – 2 SS7@256

– 448 LAPD@64 – 1 HSL (ETSI/ANSI)
– 384 LAPD@64 – 2 HSL (ETSI/ANSI) *
* Note: configuration is basically supported, but not yet tested
The signaling capacity of AS7-D units installed within anindividual BCSU must be sufficient to the max radioconfiguration:
– 500 TRX / BCSU – 16000 SDCCH / BCSU (32 SDCCH / TRX)
– 8000 TCHH / BCSU (16 TCH / TRX)
– 500 CCCH / BCSU (1 CCCH / TRX)
