operation, the channel rate for the ISU 512e can be con-
figured for 56 kbps or 64 kbps. When 64
KBPS
is selected, bandwidth
of 1x64 kbps to 8x64 kbps can be selected by setting the maximum bit
rate. When
56
KBPS
is selected, bandwidth from 1x56 kbps to 8x56
kbps is selected. See V.35 Options/Maximum Bit Rate on page 6-15 for
more information.

When the T

option is E

, the unit performs an auto-
matic 2047 BERT of the line(s) immediately following BONDING con-
nection. When set to

ISABLED
(def), no test is performed after
initialization.
Line 1 must always be connected for leased line applications
to function properly. Once line 1 is connected, the ISU 512e
will wait for all lines required to achieve the maximum bit
rate to show READY. If this does not occur, the ISU 512e
will time out and place a call using all the available lines
once line 1 becomes READY.
