DTIM8 (Digital Terminal Interface gateway Module)

The eight (8)-channel Digital Terminal Interface gateway Module supports 8 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 DTIM8 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 DTIM8 gateway using 24 AWG twisted
pair cabling.
The DTIM8 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
