T1 (24 time slots):
The use of a T1-based system.
E1 (31 time slots):
The use of an E1- based system.
Skip Timeslot 16:
Select this check box to set the module for CAS signaling in a 2MB (E1)
multiplexer.
Use Alternating Timeslots:
Select this check box to use alternating time slots (1, 3, 5, 7, 9, and so
forth). If this check box is not selected, sequential time slots are used (1, 2, 3, 4, 5, and so forth).

Circuit Configuration
Buffer Depth:
The transmit-side and receive-side each have first-in, first-out (FIFO) buffers with a
depth of 12,000 bits. The starting depth of these buffers can be set either to 256 bits for normal
synchronous operation or to half of the full depth (6000 bits) for plesiochronous operation.
Transmit Mode:
The mode for transmit side of the DS-64NC module: off at all times for receive only,
polling mode operating only when clear-to-send is asserted, at all times request-to-send/clear-to-send
handshake operational, or clear-to-send forced on at all times.
External Timing:
Select this check box to enable the external timing output. The normal condition for
the external timing output is disabled (off).
Turn On Receiver:
Select this check box to enable receive features for the module.
Data Rate Configuration
Timeslot Bit Rate:
Click
64 kbps
for the module to use 8 bits per time slot mode. Click
56 kbps
for
the module to use
7 bits per time slot mode.
Data Rate:
The total data rate that can be set to any rate from 8 kbps up to the maximum payload
capacity of the multiplexer, in increments of 8 kbps.
Timeslots:
The desired starting time slot (1 to 24 in T1 system, 1 to 31 in E1 system).
