Franklin Telecom ICT-1 CSU
T1 Interface with Channel Service Unit
Direct Connect
The ICT-1 provides a 4-wire, 100 ohm interface network access device between a T1
facility and a variety of voice and data modules. It is also used as an intelligent
multiplexer or fractional channel bank for public or private networks.
The ICT-1 multiplexes/demulitplexes up to 24 (64Kbps) DS-O channels from voice or
data modules into a DS-1 bit stream. The ICT-1 provides the PCM interface between the
platform and the external span for networks operating at 1.544Mbps
