Introduction
Product overview
In addition to traditional router functionality the NetComm NTC-6000 series cellular
routers (NTC) have been designed to facilitate the use of packet switched digital cellular
networks in legacy applications which support a V.250 (V.25ter, AT, Hayes compatible)
modem interface.
These applications often do not support the PPP and TCP/IP transport commonly supported
by the digital cellular networks.
Although the NTC-6000 series includes a cellular terminal module the external application
does not communicate directly with the digital cellular terminal, instead V.250 (AT)
commands and data are processed by the NTC.
Any V.250 commands that the NTC does not process internally may optionally be passed to
the internal cellular terminal in order to access terminal specific features.
Additionally the NTC can be configured for use as a standard circuit switched cellular data
modem.
