Description
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 in-band
loopback codes of the Wescom addressable repeater.
Configures the HiGain system to respond to the in-band
loopback codes of the Wescom Mod 1 addressable
repeater.
Configures the HiGain system to respond to the in-band
loopback codes of the Teltrend Mod 1 addressable repeater.
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-200 and HRU into their B8ZS modes.
Places both the HLU-200 and HRU into their AMI modes.
The AUTO mode is not supported. If selected, the DS1 code
defaults to AMI.
Configures the HiGain system 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 the HiGain system can also process
unframed data in AUTO mode, it is recommended that the
unframed (UNFR) 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 the HiGain system to operate in an unframed
mode. This mode disables the auto framing process and
forces the HiGain system to function as a transparent bit
pipe.
