TN-CIN voice, fax, and data multiplexer
TN-CIN voice, fax, and data multiplexer
The TN-CIN Provides QSIG and private networking transparency on demand across a switched
network. The TN-CIN integrates circuits over a single separate digital link. The circuits include
up to three G.728 LD-CELP voice or fax circuits, six CAFT voice or fax circuits, and two data
circuits. The three or six voice or fax circuits are presented as a G.703 E1 data stream that uses
either QSIG peer-to-peer or channel-associated signaling.
All voice or fax circuits support low bit rate voice compression at 8 to 16 kbps when the circuits
use CAFT. The same voice compression is supported at 16 kbps when circuits use LD-CELP.
LD-CELP voice compression supports FAX at V.29 (7200 bps). CAFT voice compression
supports FAX at V.27ter (4800 bps). The Composite port supports V.11 and V.35 at speeds up to
128 kbps.
The TN-CIN features an on-demand voice networking mode for use with time-based
communications links like ISDN. A high-speed data port is available for data applications. This
port uses V.24 or V.11 or V.35 at up to 115.2 kbps synchronous or V.24 at up to 115.2 kbps
asynchronous. The port also incorporates dynamic bandwidth allocation, also known as
variable data clocking. A low-speed V.24 data port of up to 96 kbps synchronous or 57.6 kbps
asynchronous is available for data applications.
