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.
