TL3200 Series T-1 CSU/DSUs provide the interface between customer
equipment and a T-1 or fractional T-1 facility. They support
D4 or ESF framing with AMI or B8ZS coding and provide both
front panel LCD and VT100 control.
Three
User Channels
TL3200
Series T-1 CSU/DSUs are available in three configurations.
The TL3213 provides three user channels, two V.35 synchronous
channels and a DSX1 drop-and-insert channel. The TL3212 is
similar except there is no DSX1 channel. The TL3210 provides
a single V.35 channel.
The
synchronous channels can operate at any multiple of 56 or
64 Kbps. The twenty-four DSOs may be given to either synchronous
channel, the DSX1 channel or allocated between them on a contiguous
or non-contiguous basis. Timing can be from the network, from
the V.35 channel, from the DSX1 channel or internal. |
Front
Panel and VT100 Management
TL3200
Series T-1 CSU/DSUs can be controlled from the front panel
or from a local or remote ASCII console. The front panel includes
a two-line by sixteen-character LCD display. Operating parameters
such as framing, coding and timing are selected by scrolling
through values stored in the CSU/DSU.
The
console port supports dial modems and VT100 terminals. All
operations can be performed using the three front panel pushbuttons
or from the console.
Built-in
Diagnostics
Alarm
conditions are shown on the RED/YEL front panel LEDs and described
on the LCD. Testing of the local and the remote, unattended
unit is initiated from the front panel or a VT100 console.
The user can choose from a variety of local, remote V.54 and
remote line loopbacks. Acknowledgment of remote loops is shown
on the LCD. A built-in 2047 pattern generator and checker
is also included. The TEST light illuminates with all loopbacks
and whenever the pattern generator is on. |
