Wide Bank 28 DS3 - Release 2.4 19
T3 Circuit Configuration
T3 Configuration Parameters
Keyword Description
aid Access ID. Required for ED-T3 command.
•ALL
AISC= Specifies conditions on the input (receive) side of a connection under which AIS will be
generated on the output (transmit) side of a connection. Hard-coded to
LOS&AISNAS&LOF.
AIST= Indicates the type of the AIS signal to be generated/transmitted, and the AIS signal
mode expected on input should a failure condition exist. Hard-coded to ONES.
CKTID= The circuit identification parameter contains the Common Language Circuit ID or other
alias of the channel being provisioned. This is an ASCII string limited to 32 characters.
CMDMDE= Indicates command execution mode. Hard-coded to FRCD, meaning that commands
may override existing parameter settings in order to execute.
FMT= Indicates DS3 digital signal format. Values are:
•CBIT
•M23
IDLE= Indicates DS3 idle signal is used or not used. Hard-coded to N.
LBO= Indicates line build out setting. Values are:
• 1 – short connections (less than 50')
• 2 – long connections (50' or longer)
LINECDE= Indicates DS3 line code. Hard coded to B3ZS.
MCOND= Specifies conditions to be monitored on the input side of the connection. Hard-coded to:
LOS&RAI&AISNAS&LOF&T-BERL&RTCLK&IMPROPRMVL&INT
&PWR&INTERR&CONTEQPT&BPV
OMODE= Specifies what will be transmitted from the DS3 output port. Values are:
• NORM – normal
• AIS – Alarm Indication Signal
TMG= Timing Source. Applies only to T3 modifier. Values are:
• INT – Internal Stratum 4E clock
• EXT – External Clock (44.736 Mbps)
• LINE – Slave to DS3 Line
TMGLOCK= Timing Lock. Applies only to T3 modifier. Indicates whether provisioned timing source
is to be locked to disable automatic source switching. Values are:
•Y – yes
• N – no
XBIT= Indicates how the X-bits are handled for this particular channel. Hard-coded to PASS,
meaning it will pass the X-bits with no modification.
XBITRCV= Indicates the usage of the outgoing X-bits. Hard-coded to ALM1, meaning all the X-
bits equal to 1 for indicating incoming remove alarm.
XPOL= Indicates the value/polarity to which the outgoing X-bits are forced. Hard-coded to
ALM1, meaning the Wide Bank will set X-bits to one for indicating alarm.
