General information Aastra 650c - TFT-Colour display (2", 176 x 220 dots, 65536 colours) - 1 hotkey / 3 sidekeys (programmable) - 3 softkeys (of which 2 are programmable) - 2 programmable navigation keys - Caller list for 50 entries - Redial list for 30 entries - Local phone book for 200 entries - Headset connection via cable or Bluetooth - Mini USB connection - microSD card interface - Safety class IP 50 - Supports CAT-iq broadband audio The Aastra 650c telephone supports the new CAT-iq DECT standard. CAT-iq stands for "Cordless Advanced Technology - internet and quality", and allows high-quality broadband telephony (compatible with Aastra Hi-Q audio). Significantly larger data rates can be transmitted with CAT-iq thanks to the G.722 audio codec, which ensures the high audio quality. In order to benefit from this, your telephone system and DECT transmitter (RFP) - plus the telephone of your call partner - must also support this codec. The voice connection must be made as before via Internet (IP). The new standard is supported by Aastra SIP-DECT® systems (as of Release 3.0) and through the use of the latest DECT transmitters (e.g. RFP 35, 37 and 43) throughout the system. In contrast to conventional telephones that can also support broadband telephony, CAT-iq offers the security of being certified by an independent laboratory. This ensures that all other important components (e.g. loudspeaker, microphone and amplifier) support this improved audio standard in addition to the codec. Differences between Aastra 6x0d and 6x2d Devices of the Aastra 6x2d series (612d, 622d, 632d) are identical in design to those of the older 6x0d series (610d, 620d, 630d). However, 6x2d devices are equipped with state-of-the-art technology; they are quicker at accessing data and have a greater storage capacity for other, future applications. Difference in appearance: Aastra 6x0d have a blue "A" in the Aastra device logo Aastra 6x2d have a black "A" in the Aastra device logo 2

- Supports CAT-iq broadband audio
The Aastra 650c telephone supports the new CAT-iq DECT standard. CAT-iq stands for “Cordless
Advanced Technology – internet and quality”, and allows high-quality broadband telephony (com-
patible with Aastra Hi-Q audio). Significantly larger data rates can be transmitted with CAT-iq thanks
to the G.722 audio codec, which ensures the high audio quality. In order to benefit from this, your
telephone system and DECT transmitter (RFP) – plus the telephone of your call partner – must also
support this codec. The voice connection must be made as before via Internet (IP). The new standard
is supported by Aastra SIP-DECT® systems (as of Release 3.0) and through the use of the latest DECT
transmitters (e.g. RFP 35, 37 and 43) throughout the system.
In contrast to conventional telephones that can also support broadband
telephony, CAT-iq offers the security of being certified by an independent
laboratory. This ensures that all other important components (e.g. loudspe-
aker, microphone and amplifier) support this improved audio standard in
addition to the codec.

6x0d series (610d, 620d, 630d). However, 6x2d devices are equipped with state-of-the-art tech-
nology; they are quicker at accessing data and have a greater storage capacity for other, future
applications.
