Description
Configures the HLU-200 to ignore the 2-in-5 Smart-Jack loopback
command.
Enables the HLU-200 to respond to the 2-in-5 Smart-Jack
loopback command.
Configures the HiGain system to respond to the generic
(3-/4-/5-/6-in-7) in-band loopback codes.
Configures the HiGain system to respond to the Teltrend
addressable repeater in-band loopback codes.
Configures the HiGain system to respond to the Wescom
addressable repeater in-band loopback codes.
Configures the HiGain system to respond to the Wescom Mod 1
addressable repeater in-band loopback codes.
Configures the HiGain system to respond to the Teltrend Mod 1
addressable repeater in-band loopback codes.
Disables powering to the HRU and/or doubler over the HDSL
pairs.
Enables powering to the HRU and/or doubler over the HDSL pairs.
Places both the HLU and HRU into their B8ZS modes.
Places both the HLU and HRU into their AMI modes.
The AUTO mode is not supported. If selected, the DS1 code
defaults to AMI.
Confirms that all operating parameters (except Margin) are to be
updated to the new selections.
Prevents newly selected operating parameters from being
updated. These options remain as they were before the setting
options procedure was started.
Configures HiGain to operate in an auto-framing (AUTO) mode in
which it continuously searches the input T1 bit stream for a valid
SF or ESF frame pattern. This feature is required for fractional T1
applications (DS0 blocking) where it insures proper channel time
slot alignment. While HiGain can also process unframed data in
this AUTO mode, it is recommended that the UNFR mode be used
for all unframed applications. Using the AUTO mode for unframed
applications runs the risk of detecting "pseudo valid" frame
sequences, which can affect the data integrity.
Configures HiGain to operate in an unframed mode. This mode
disables the auto framing process and forces HiGain to function as
a transparent bit pipe.
