Reply To: CAMEL parameters for ALCATEL 2000 system


Hi Tally,

In CAP, OCSI and TCSI mark are used for CAMEL subscribers. When LU, the OCSI and TCSI mark stall in VLR data base. When subscriber make a call, IDP(initial DP) was triggering directly to IN servers, and MSC/VLR is not intelligent enaugh to now that IN server is not available or not.
One case, When PPS system is not available, here SS7 connection between MSC/VLR and IN servers also not available. When this happen the conversation between IN and MSC/VLR also not available, So call will be rejected.
