The DTIM24 (Digital Terminal Interface gateway Module) supports 24 digital keysets (LKD and
LDP models). Keysets have access to all the resources of the iPECS as well as keyset
functionality and simple one-button feature access. The DTIM24 contains a processor for IP to
TDM and signaling conversion as well as DSP circuitry to provide transcoding for each channel.
Digital keysets can be connected up to 300 meters from the DTIM24 gateway using 24 AWG
twisted pair cabling.
The DTIM24 includes a 10/100 Base-T Ethernet interface as well as packet voice processing
functions. The Ethernet port incorporates auto MDI, MDIX switching, therefore, both straight and
cross cables can be used.
