Model Options
Selecting Model options from the Config<Global menu allows you to specify the model parameter
settings listed in Table 4-17.
Table 4-18 Execute Menu Model Parameter Settings
Setting Defaults Description
Optimize LDI Ports YY
—NMT tries to optimize the cost of the LDP cards by using lower cost
LDP-4 cards instead of LDP-8 cards.
If no, NMT only uses LDP-8 cards. You can still explicitly call for an
LDP card with a specific line count.
Group Bursty Conns YY
—NMT groups connections when their number exceeds the maximum
number of LCONS. An LCON is a resource required for each network
route with similar properties. The grouping of connections allows more
routed connections in a network.
If no, NMT does not group connections and fails to build a site when a
grouping is required.
Distribute Groups YY
—NMT optimizes the grouping of connections to smooth network
loading.
If no, NMT does not optimize grouping.
Use SRM-3T3 on
MGX 8220
NY
—NMT will provision an SRM-3T3 service redundant module on all
MGX 8220 shelves.
If no, NMT will provision an SRM-3T3 service redundant module only if
the case connection interface requires it.
Bundle Voice with CCS YY—NMT will bundle voice connections with CCS signalling and create
a transparent connection (type T) to carry line signalling.
If No, NMT will not bundle voice connections; it is your responsibility to
specify the channel for CCS signalling.
Use Preferred Route YY
—route the connection with the preferred route if one exists.
If no, use the current route.
Note This does not apply to failure analysis.
Note CET Extractions will set this field to ‘N’.
Use Port ID YY— NMT assigns slots and ports based on hub and feeder IDs.
If no, NMT treats all ID fields as though they were zero filled, and
provisions links and connections using its own algorithms.
Port ID Over Redundancy NY
—the system eliminates the redundant card if another card has
requested the hub ID of the backup card.
If no, the system gives backup cards precedence over another card that
was assigned the same port. In this case, NMT overrides the hub ID and
moves one of the connections to a different location.
New Share with Port ID NY
—NMT allows connections IDs of zero to share ports with connections
having IDs other than zero.
If no, NMT does not allow this.
