DATASET 2 100 Series Description 
Terminate B channel command, which it can do because the D channel is active while 
the B channel session is in progress. 
Data is clocked to and from the shift registers at a constant rate by the synchronous 
clocks on the PI.5232 interface. The data set firmware converts this data into packets 
which are passed through the PABX in Ul frames. No error detection or correction is 
performed on this data; synchronous data usually includes its own error detection and...

Timing Modes 
10.6 There are four modes of timing available with a DATASET 2100 series that are used 
according to the current mode of operation. 
Internal - The Internal clock is used when the DATASET 2100 Series is operating in 
Data Communication Equipment (DCE) mode. The transmit clock (SCT) to the Data 
Terminal Equipment (DTE) is generated within the dataset’s baud rate generator and 
is not synchronized with PABX timing. The dataset’s receive clock (SCR) to the DTE 
is...

Standalone DATASET 2103 Description 
10.9 A Standalone DATASET 2103 is packaged in a fiat case which can be placed under 
a standard desk telephone set. It is functionally the same as the Rack Mounted 
DATASET 2102 (they share the same base printed circuit board). The Standalone 
DATASET 2103 can be connected to the PABX using a four-wire connection; two 
wires connect the dataset to the Digital Line Card, and two different wires connect the 
telephone set Tip-Ring pair...

DATASET 2100 Series Description 
Circuit Description 
10.10 The DATASET 2100 Series circuit contains six basic blocks, as shown in Figure 10-3. 
The microcontroller is the central processor for the dataset; it contains two timers, the 
BAUD rate generator, the Universal Asynchronous Receiver Transmitter (UART) and 
the system High-level Data Link Control (HDLC). The switches on the data set inter- 
face directly to the microcontroller; this way, the firmware can override the switch 
settings.
