3.1.13.2 WTIM8
The Wireless Terminal Interface gateway Module (WTIM8) provides connections for eight (8)
Ericsson-LG Enterprise multi-channel DECT Base stations. The DECT Base station acts as the
Remote Fixed Part (RFP) defined in the DECT specifications. The GDC-400B, GDC-600B and
GDC600BE DECT Base Stations are supported.
DECT handsets can be used if the Base station is connected to the WTIM8 and the proper
Attendant programming is completed. The WTIM8 contains a processor for IP to TDM and
signaling conversion and DSP circuitry to provide transcoding for each channel. The Base station
can be connected to the WTIM8 up to 600 meters from the gateway using 24 AWG twisted pair
cabling.
The WTIM8 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.
