Network-wide PU groups

Network-wide call pickup

In the case of ECMA or Cornet-NQ networks between an OpenScape 4000 and a Hicom 300 E V2.0 or a Hicom 300 E V1.0, the COT parameters NQNP and NQPI must be set on the tie trunk circuits of the OpenScape 4000, which lead to the Hicom 300 nodes of system version Hicom 300 E V2.0 (V3.6) or Hicom 300 E V1.0 (V3.5).

If the COT Parameter NQNP or NQPI is not set, the connected number is missing in the call data record under CALL PICKUP. The error occurs because the FACility signal with a call pickup information element is not understood by the older Hicom 300 system versions Hicom 300 E V2.0 or Hicom 300 E V1.0.

NQPI = CorNet-NQ network-wide call pickup information for the network-wide PU groups feature is not supported between the calling and called subscribers (trunks that do not support NQ Operations Call Pick Info)

NQNP = CorNet-NQ network-wide call pickup between the calling and called subscribers is not supported (trunks that do not support NQ Operations Call Pick-up)
