used on any type of DECT system. It thus represents
the smallest common denominator of all manufacturer-
specific variants of the DECT standard.
• An important limitation in the GAP standard is that
external handover is not possible. For this reason
connection handover is used, which is supported by
GAP terminals.
• The operation of GAP-capable telephones is
comparable to that of analogue terminals. For
example, features can be called up via ‘*’ and ‘#’
procedures.

A handover is similar to roaming, but occurs during an
ongoing call. A handover normally takes place “in the
background”, without disrupting the call (seamless
handover).

• 13-digit identification code for PPs
• Example: 00019 0592015 3
(the final digit is the checksum).
• The code is represented in decimal form.
• This code is globally unique.

Portable Access Rights Key
Access code for the Portable Part. This code determines
whether a PP can access a particular DECT system. Used
for unique selection of the system at handset
enrolment/subscription time. Provided with the Aastra
OMM Activation Kit and unique to each SIP-DECT
deployment.

Roaming
While in motion, the PP performs ongoing measurements
to determine which RFP is best received. The one that
can be best received is defined as the active RFP. To
prevent the PP from rapidly switching back and forth
between two RFPs that have similar signal strength,
certain threshold values are in effect.
