General Description

The Line Card Interface Controller, STLC5460, is a monolithic switching device for the path control of up to 128 channels of 16, 32, 64 kbps bandwidth.

Two consecutive 64 kbps channels may also be handled as a quasi single 128 kbps channel.

For these channels, the LCIC performs nonblocking space time switching be
