Telephones and Peripherals 8
This chapter covers Digital Telephones (DPs) and Internet Protocol Telephones (IPTs) and
peripherals that are compatible with Strata CIX telephone systems. The DP5000-series and the
IPT2000-series telephones have a number of enhanced features.
DP5000-series Digital Telephones
The DP5000-series telephones replace the DKT3200-series telephones in the Toshiba product line.
All three generations of telephones, DKT2000, DKT3200 and DP5000, can co-exist with full
functionality in one Strata CIX system with Release 5.1 software or above.
Although the DP5000-series telephones can be used on a CTX28 they will have limited
functionality.
The DP5000 telephones have three operational modes:
• When connected to Release 5.1 CIX systems, they will automatically run in DP5000 Mode.
• When connected to CIX systems with older than Release 5.1 (including Release 3) the
DP5000-series telephones will automatically act as DKT3200 telephones; DP5000-series
telephones can also be programmed to act as DKT2000 telephones.
• When connected to a PDKU card DP5000-series telephones automatically act as DKT2000
telephones.
• The DP5000 Backlight feature will function on all Strata CIX or CTX systems, regardless of
the system software version.
