Cordless Single Line Headset Telephone, CT-11 — P/N 730090
The CT-11 is a 2.4GHz cordless headset which connects
to an analog port or an analog telephone line as a stand-
alone unit or to an analog port adapter (APR, P/N
0890056). When the APR is set up as the same extension
of the telephone, you can use the headset to answer and
make calls using the cordless headset. The CT-11 offers
Caller ID, but only if it is connected to an analog port on
an analog station card. The CT-11 will not receive Caller
ID if it is connected to an APA or APR adapter (these
adapters do not output Caller ID).
The number of units which can be used on the system is
greatly affected by the environment. The closer or
smaller the area, the smaller the number of units which
can be used. It is recommended to start with 3 or less. If
there are no con
fl
icts between the telephones, you can try adding additional units (up to 5 would be
the recommended maximum).
When using wireless LAN, keep in mind that although there should not be a problem with interfer-
ence from WLAN’s, 802.11b and 802.11g both share the same frequency as the CT-11 telephone.
In theory, the CT-11 is a narrow band high power device where as the 802.11b and 802.11g are both
wide band low power technologies. Therefore, the higher power CT-11 could disrupt the low power
device and slow the data network. There are, however, many exceptions to this (for example, if the
WLAN uses highly directional antennas, higher power relays between buildings, etc.). The CT-11
can not lock down channels, unlike the 802.11b and 802.11g.
