Marketing Information |
|
The T-336 is a series of high performance,
synchronous and asynchronous, full-duplex, multi-standard standalone or
rack-mounted modem. It is designed for use on 2-wire dial-up and 2/4-
wire leased-line circuits.
The T-336 is fully compliant with ITU-T V.34 recommendation as well as
being compatible with ITU-T recommended V.32bis/V.32, V.22bis, V.23 and
V.21 international standards while operating at 33600, 31200, 28800,
26400, 24000, 21600, 19200, 16800, 14400, 12000, 9600, 7200, 4800, 2400,
1200, and 300 bits per second.
In V.34 mode the T-336 provides full-duplex operation at up to 33.6Kbps
on a 2/4-wire PSTN line with features like line probing, symbol rate and
carrier frequency automatic selection. A range of performance enhancing
techniques are available for V.34 mode, including adaptive precoding,
adaptive pre-emphasis, nonlinear encoding (Warping), constellation
expansion, multidimensional trellis coding, transmission power back-off
(power
drop), V.8 standard modem initialization and shell mapping. An in-band secondary channel allows the
user to monitor and control the remote site unit. The T-336 series also
offers auto callback and leased-line security checks in addition to the
dialup security checks.
The TRS32 rack can accommodate up to 16 modem cards with 32 ports,
control unit and single or dual redundant power unit. Dual redundant
power supply meaning if one power does fail, the other one is capable of
powering the entire rack. |
