chg-lsopts

Use this command to administer the thresholds for IPSG-M3UA linksets and to set SLS bit rotation for ANSI linksets.

Parameters

lsn (mandatory)

Linkset name. The name of the linkset. Each linkset name must be unique in the system.

Range:: ayyyyyyyyy
1 alphabetic character followed by up to 9 alphanumeric characters

icnimap (optional)

Incoming NI Map. The NI mapping for incoming MSUs on a linkset. The NI value in the incoming MSU is changed to the value specified by this parameter before processing the message.

Range:

itui2ituis: Map ITU International to ITU International Spare
ituis2itui: Map ITU International Spare to ITU International
itun2ituns: Map ITU National to ITU National Spare
ituns2itun: Map ITU National Spare to ITU National
none: NI mapping is not performed on the specified linkset.

Default:

No change to the current value

System Default:

none

numslkalw (optional)

Number of signaling links allowed. The IS-NR link count threshold required for an IPSG-M3UA linkset to transition from the Restricted or Prohibited state to the Allowed state.

Note:

When the number of IS-NR links in an IPSG-M3UA linkset transitions from a value less than numslkalw to a value equal to or greater than numslkalw, the linkset transitions to the allowed state.

Range:: 0 - 16
0 —The IS-NR link count threshold value for an IPSG-M3UA linkset is considered to be half of the number of links configured in the linkset.
Default:: No change to the current value
System Default:: 1

numslkproh (optional)

Number of signaling links required to prohibit a linkset. The IS-NR link count threshold required for an IPSG-M3UA linkset to transition from the Restricted or Allowed state to the Prohibited state.

Note:

When the number of IS-NR links in an IPSG-M3UA linkset transitions from a value equal to or greater than numslkproh to a value less than numslkproh, the linkset transitions to the Prohibited state.

Range:: 0 - 16

Note:
0 —The IS-NR link count threshold value for an IPSG-M3UA linkset is considered to be half of the number of links configured in the linkset.
Default:: No change to current value
System Default:: 1

numslkrstr (optional)

Number of signaling links required to restrict a linkset. The IS-NR link count threshold required for an IPSG-M3UA linkset to transition from the Allowed state to the Restricted state.

When the number of IS-NR links in an IPSG-M3UA linkset transitions from a value equal to or greater than numslkrstr to a value less than numslkrstr and greater than numslkproh, the linkset transitions from the Allowed state to the Restricted state. Transition from the Prohibited state to the Restricted state is not supported.

Range:: 0 - 16
0 —The IS-NR link count threshold value for an IPSG-M3UA linkset is considered to be half of the number of links configured in the linkset.
Default:: No change to current value
System Default:: 1

ognimap (optional)

Outgoing NI Map. The NI mapping for outgoing MSUs on a linkset. The NI value in the processed MSU is changed to the value specified by the ognimap parameter for that linkset before routing the message to the intended destination.

Range:

itui2ituis: Map ITU International to ITU International Spare
ituis2itui: Map ITU International Spare to ITU International
itun2ituns: Map ITU National to ITU National Spare
ituns2itun: Map ITU National Spare to ITU National.
none: NI mapping is not performed on the specified linkset.

Default:

No change to the current value

System Default:

none

pct (optional)

Point Code and CIC Translation. This option specifies whether to apply PCT to the specified linkset.

Range:

off: do not apply PCT to the linkset
on: apply PCT to the linkset

Default:

off

rsls8 (optional)

Rotate SLS by 5 or 8 bits. This parameter specifies whether the signaling link selector (SLS) of the incoming ANSI linkset is rotated by 5 or 8 bits.

Range:

yes: 8 bit SLS of the incoming linkset is considered for bit rotation
no: 5 bit SLS of the incoming linkset is considered for bit rotation

Default:

No change to the current value

System Default:

no

Example

The following example changes the threshold value of the numslkproh parameter to 3 for an IPSG-M3UA linkset.

chg-lsopts:lsn=lsm3ual:numslkproh=3

The following example sets the incoming and outgoing NI Mapping for a linkset.

chg-lsopts:lsn=lsnimap1:icnimap=itun2ituns:ognimap=ituns2itun

The following example sets 8 bit incoming bit rotation for an ANSI link set

chg-lsopts:lsn=lsl:rsls8=yes

chg-lsopts:lsn=ls111:pct=on

Dependencies

The value specified for the numslkproh parameter cannot be greater than the value specified for the numslkrstr parameter.

The value specified for the numslkrstr parameter cannot be greater than the value specified for the numslkalw parameter.

The value specified for the lsn parameter must indicate an IPSG-M3UA linkset before the numslkalw, numslkproh, and numslkrstr parameters can be specified.

The value specified for the numslkalw, numslkproh, or numslkrstr parameter cannot be greater than the number of links configured in the IPSG-M3UA linkset.

The ITU National and International Spare Point Code Support feature must be enabled before the icnimap and ognimap parameters can be specified.

The icnimap and ognimap parameters must be specified together in the command.

The NI mapping for incoming messages in a linkset must be compatible with the NI mapping for the outgoing messages.

Values for the icnimap and ognimap parameters other than none can be specified only for ITU-I and ITU-N APCs of the linkset.

An ANSI linkset must be specified by the lsn parameter before the rsls8=yes parameter can be specified.

The ISLSBR feature must be enabled before the rsls8 parameter can be specified.

A PCT quantity feature must be enabled before the pct parameter can be specified.

Notes

NI Mapping Parameter Compliance Rules

The values specified for the icnimap and ognimap parameters for a linkset must be compatible. Table 4-12 shows the relationship between the parameters for a linkset.

Table 4-12 NI Mapping Rules

ICNIMAP	OGNIMAP
ITUI2ITUIS	ITUIS2ITUI
ITUIS2ITUI	ITUI2ITUIS
ITUN2ITUNS	ITUNS2ITUN
ITUNS2ITUN	ITUN2ITUNS
NONE	NONE

If the rsls8=yes parameter is specified, then 8 bits of the Incoming ANSI SLS are used for the ISLSBR feature. If the rsls8=no parameter is specified, then 5 bits are used.

Table 4-13 summarizes the cases in which rotation is done on the Incoming ANSI SLS bits:

Table 4-13 Incoming SLS Bit Rotation for ANSI Linksets

Number of Incoming SLS Bits	RSLS8	Valid range of values of ISLSRSB	SLSCNV/SLSCI	If Incoming SLS bits are rotated or not
5	No	1-5	No	Yes
5	No	1-5	Yes	Yes ( Lower 5 bits)
5	Yes	1-8	No	No
5	Yes	1-8	Yes	Yes
8	No	1-5	Yes/No	Yes (Lower 5 bits)
8	Yes	1-8	Yes/No	Yes
