AUXILIARY
FUNCTIONS
ESF NET
—
The ESF out-of-band network loop
codes allow the T-BERD 107A to establish a
loopback with a compatible terminal or respond
to a network loop code. The ESF out-of-band
network loop-up code is 1111 1111 0100 1000.
The ESF out-of-band network loop-down code
is 1111 1111 0010 0100. If this choice is selected
when the mode is not an ESF operating mode,
the FAC2 loop code is transmitted instead.
When the LOOP CODES switch is in the PROG
position, the CATEGORY switch is used to select
USER, one of the intelligent network equipment
codes (Smart Loopback/Command Codes Option
required), or ESF DL. The T-BERD 107A does not
respond to intelligent network equipment loop codes.
The availability of intelligent network equip-
ment loop codes is determined by the AUX
SMARTNET function. If the intelligent network
equipment is not selected or is set to NONE in the
AUX SMARTNET function, the selection does not
appear in the AUX LOOPCODE function. Refer to
Appendix D for tables that list the intelligent network
equipment, available addresses, and commands. The
USER, intelligent network equipment type, and ESF
DL selections are described as follows:

The in-band, 3- to 8-bit program-
mable, loop code settings of the AUX PGM
LPUP and AUX PGM LPDN functions are
transmitted or responded to by the T-BERD
