About the Portable Parts

Portable Part (PP) is DECT standard terminology and in the context of the
SIP-DECT solution is interchangeable with Aastra DECT 142 Handset.
Please be aware of differences in regulatory requirements between North
America and all other areas of the world. These differences lead to different
PP variants which use specific frequency bands and field strengths:
• Aastra Phone 142 (EMEA)
Frequency Band 1.880 to 1.900 Mhz
-
120 duplex channels
-
250 mW (maximum output per active channel)
-
- 10 mW (average output per active channel)
• Aastra DECT 142 DECT142 (NA)
Frequency Band 1.920 to 1.930 Mhz
-
- 60 duplex channels
100 mW (maximum output per active channel)
-
- 5 mW (average output per active channel)
In addition to the Aastra DECT 142 Handset, standard 3rd party DECT GAP
phones may operate on the SIP-DECT solution. But the functionality may be
limited by the characteristics of the 3rd party DECT phone.
