Table 573-1. HLX Loopback Configuration Fields, continued
FIELD TYPE OPTIONS DESCRIPTION DEFAULT
HLXR NID Loopback
Toggle UNIT SWITCH
Version E HLXR only:
Selects
NID setting (enabled) for the
HLXR.
Version D or earlier HLXR:
Selects NID setting (either enabled
[default] or disabled) on the HLXR.
When the HLXR is provisioned to
function like an NID, it supports
inband and out-of-band loopback
codes.
MPU V5.1:
UNIT SWITCH
MPU V5.2:
ENABLED
ENABLED Enables response to NID loopback
codes and overrides hardware
configuration settings.
DISABLED Disables response to NID loopback
codes and overrides hardware
configuration settings.
HLXR Activation
Code
(“Activation Code” is
equivalent to
“Programmable
Code.”)
Input 16 binary characters (0’s
and 1’s) must be entered.
16-bit codes can be programmed to
any 16-bit binary value except: all 0s,
all 1s, or a value that is already used
in another 16-bit code.
The signal is
sent inband. HDSL units go to
loopup state when they are in armed
state. Loopup is activated for selected
units. Detection time is 3 secs.
MPU V5.1:
1100 0111 0100 0010
MPU V5.2:
1100 0111 0101 0100
HLXR Programmable
Lpbk
Toggle ENABLED Enables response to programmable
loopback codes and overrides
hardware configuration settings.
DISABLED
DISABLED Disables response to programmable
loopback codes and overrides
hardware configuration settings.
One HRX in system
only:
HRX or HRX1
Activation Code
(“Activation Code” is
equivalent to
“Programmable
Code.”)
Input 16 binary characters (0’s
and 1’s) must be entered.
16-bit codes can be programmed to
any 16-bit binary value except: all 0s,
all 1s, or a value that is already used
in another 16-bit code. The signal is
