Description
EQL
EXT*
Replaces the internal equalizer with a 12 Vp/p driver for external equalizers.
0
Sets Equalizer to DSX-1 for 0-133 feet.
133
Sets Equalizer to DSX-1 for 133-266 feet.
266
Sets Equalizer to DSX-1 for 266-399 feet.
399
Sets Equalizer to DSX-1 for 399-533 feet.
533
Sets Equalizer to DSX-1 for 533-655 feet.
LPBK
DIS
Configures HiGain to ignore all in-band “smart-jack” loopback commands.
ENA*
Enables HiGain to recognize all in-band “smart-jack” loopback commands.
SPLB
GNLB*
Configures HiGain to respond to the generic (3/4 in 7) in-band loopback codes.
A1LB &
A2LB
Configures HiGain to respond to the Teltrend addressable repeater in-band
loopback codes.
A3LB
Configures HiGain to respond to the Wescom addressable repeater in-band
loopback codes.
A4LB
Configures HiGain to respond to the Wescom Mod 1 addressable repeater in-band
loopback codes.
A5LB
Configures HiGain to respond to the Teltrend Mod 1 addressable repeater in-band
loopback codes.
PWRF
DIS
Disables line powering to the HRU.
ENA*
Enables line powering to the HRU.
ZBTS
ON
Tells HiGain that the ESF frame is operating in its ZBTSI mode.
OFF*
Tells HiGain that the ESF frame is operating in its normal non-ZBTSI mode.
ESAL
17
Activates (closes) the minor alarm relay contacts on pins 12 & 14 and flashes the
red STATUS LED when 17 Errored Seconds (ES) (17 HDSL CRC errors on either
HDSL loop or a total of 17 BPVs) occur within a 24-hour period.
170
Activates (closes) the minor alarm relay contacts on pins 12 & 14 and flashes the
red STATUS LED when 170 ES (170 HDSL CRC errors on either HDSL loop or a
total of 170 BPVs) occur within a 24-hour period.
NONE*
Prevents generation of a minor alarm due to excessive Errored Seconds. (Note: this
is the recommended setting for protection switching applications.)
LBTO
NONE
Disables automatic time-out cancellation of all loopbacks.
20
Sets automatic cancellation of all loopbacks to 20 minutes after initiation.
60*
Sets automatic cancellation of all loopbacks to 60 minutes after initiation.
120
Sets automatic cancellation of all loopbacks to 120 minutes after initiation.
ALM
DIS*
Opens the minor alarm relay contacts, if closed, and disables activation of the minor
alarm relay when a minor alarm condition occurs.
ENA
Enables activation of the minor alarm relay when a minor alarm condition occurs.
DS1
AUTO
The HLU and HRU independently monitor their incoming DS1 bit streams for the
B8ZS pattern. If either unit detects this pattern, it enters its B8ZS mode. It reverts
back to its AMI mode if no B8ZS patterns are received for 5 seconds.
B8ZS
Places both the HLU & HRU into their B8ZS modes.
AMI*
Places both the HLU & HRU into their AMI modes.
