1 - 5 DSOs Assigned: These five positions select the bit rate and the number of DSOs assigned to the
channel (refer to the table below).
6
Rate Multiplier: Sets the multiplier for the input timing (refer to the table below). The unit oper-
ates at any data rate that is a multiple of 56 or 64 kbps.
7
Channel Assignment: The Contiguous mode assigns the channels as a block beginning at DS0
channel 1. If ‘Alternate’ is selected, channel assignments are made with an idle channel following
each data channel.
8
Control Lines: ‘On’ permanently sets the CTS, DSR, and CD leads to ON. With ‘Follow’, the
DSR lead follows T1 sync, the CTS lead follows RTS, and the CD lead follows the density status
of the incoming T1 signal (
≥
175 zeros = CD OFF). The TM line goes high when the unit is in a
local or remote test mode.
9
Data Invert: Determines whether the data bits are inverted.
NOTE: The ‘A’ position is the factory default for
all switch settings. If a particular user configuration
requires that a switch be placed in the ‘B’ direction,
then mark this sheet for future reference.
