DKT2204-CT Cordless Digital Telephone

Toshiba’s reliable 2204-CT telephone was first released in 2003, manufacturing ceased in March 2010 and manufacturer support ended March 2017.

The DKT2204-CT cordless digital telephone is compatible with all Strata CTX/CIX and Strata DK telephone systems (except Strata DK24/56/96, Release 3). All it requires for connection is a digital station port.

The DKT2204-CT uses 900 MHz spread-spectrum technology. Spread-spectrum technology provides five to seven times greater range than conventional cordless telephones.  The 2204-CT base station has a typical range of up to 300-400 feet, 1.1 miles if unobstructed.  While the DKT2204 provides more range than the DKT2304, the 2204 has only 10 available channels while the 2304 has 30 channels.

Features for the benefit of enhanced productivity:

  • Single button access to: Message, Menu/Mute, Speaker, Redial, Conference/Transfer, Talk, and Hold

The DKT2204-CT cordless digital telephone has 10 operating channels available.  A common misconception is that this limits a customer to 10 cordless telephones.  This is not the case.  Each cordless digital telephone can operate on any of the 10 channels.  When you turn on a cordless digital telephone, the telephone selects an available channel within its’ range.  In the given cordless range, 10 simultaneous calls can be made.  In most businesses, it is unlikely that all 10 channels will be in use at the same time.  Typically, 20 to 30 telephones can share the 10 channels.  Another factor is the distribution of the telephones in a facility.  If your cordless digital telephones are disbursed throughout a facility, there should not be contention for channels.  If there are more than 10 cordless digital telephones in one area and 10 users are using their cordless telephones, an 11th user would not be able connect at that time.
