Sip Dect Capacity Limitations - Nortel CS 1000 Manual

16 Product overview
If you use a twinned configuration for a DECT handset, the corresponding
IP or TDM phone correctly reflects the current state of MWI, if it receives
MWI notifications for the Primary DN from CallPilot.

SIP DECT capacity limitations

The following capacity limitations apply to SIP DECT:
•
a maximum of 12 simultaneous calls for each DAP
•
a maximum of 256 DAPs on each network (where handover and
synchronization between DAPs is possible)
•
a maximum of 6000 DECT handsets on each SIP DECT system
(potentially, several isolated SIP DECT systems can connect to CS
1000)
•
a maximum of 1000 simultaneous calls on each network
•
a maximum of 25 subscription records for each DAP
If the planned number of DECT handsets in a SIP DECT system is
equal to M, and the number of DAPs in that system is equal to N, M
must be less than or equal to N*25.
Consider the following additional capacity limitations based on the CS
1000 configuration characteristics.
•
The number of available UEXTs is limited by the number of available
virtual Telephone Numbers (TN) in the system.
•
The number of DNs available for DECT handsets depends on the
configured dialing plan and the availability of the Directory Number
Expansion (DNXP) package (150).
