RFP mixed installations
In sites (or whole systems) with disabled Hi-Q audio, an arbitrary mixture of
RFP (L) 32/34 IP / RFP (L) 42 WLAN and RFP (L) 35/36/37 IP / RFP (L) 43 WLAN is
allowed. No further restrictions appear for mixed installations.
DECT XQ
The DECT radio communication generally suffers from attenuation and radio wave reflection.
Especially if a building’s walls and ceilings contain a higher portion of metal-based material
or if larger metal surfaces are present, the DECT XQ improves the radio communication
between an RFP and an Aastra 600d / Aastra 650c portable part at the expense of DECT
channel capacity (see 9.3). Enable this feature for some or all of your RFPs (see chapter
7.6.3, “DECT settings” or chapter 8.7.1.2, “DECT tab”).
It is not possible to have DECT XQ audio combined with Hi-Q audio within the same
connection.
Three operating modes regarding audio quality are selectable at the Aastra 650c handset:
standard audio, Hi-Q audio and automatic.
•
In case that an Aastra 650c operates in Hi-Q audio mode, it will exclusively establish
wideband connections and not switch to narrowband later on. An Aastra 650c in this mode
will ignore the XQ capability of the RFP.
•
In case that an Aastra 650c operates in standard audio mode, it will exclusively establish
narrowband connections and not switch to wideband later on. An Aastra 650c in this mode
will switch to DECT XQ and back as necessary.
•
In case that an Aastra 650c operates in automatic mode, the connection establishment
depends on whether the current base provides DECT XQ or not. If DECT XQ is available,
a narrowband connection will be established. Otherwise a wideband connection will be
established.
UTF-8
The UTF-8 support allows the presentation of a wider range of language specific characters
e.g. umlauts and eases the internationalization/localization. Since SIP–DECT 2.1 the OMM
and the Aastra 600d handset family support UTF-8 for text messaging.
With the SIP–DECT 3.0 the OMM and the Aastra 600d / 650c handsets support an extended
character set for
•
User parameter (configurable via WEB, OMP or external user configuration files)
– System name
– User name
– Number
•
SIP “display names” und SIP “user id’s” of incoming and outgoing calls
•
Call logs
•
LDAP directory access
•
XML terminal interface objects
Be aware that this feature needs at least following handset firmware releases:
•
Aastra 600d: firmware release 4.00 or later
•
Aastra 650c: firmware release 1.00 or later
