Least Cost Routing (Lcr) - Toshiba Strata DK14 General Description Manual

Calling Number Identification Services (CNIS)
CNIS features provide "Calling Party Information" to the network (outgoing calls) and from the
network (incoming calls). There are four types of CNIS services:
Number Provisioning for outgoing calls is controlled by subscription parameters with your
telco provider. The choice is for the number to be necessary or not. The number sent is based
on the call originator and the call type. The originator can be a tandem call, a station (with or
without DID), or a station with a designated number. The type of call refers to whether it is a
direct or redirected (call forwarded) call.
For a tandem call, the Calling Party Number digits received are the digits that will be sent. For
a direct station call, the default number assigned to the selected service, and which is
programmed into the Strata DK as the Listed Directory Number (LDN), will be the number
sent. In this case, the system can send a fixed number (assigned in the system) or it can use the
DID programming to determine the number to be sent.
Number Screening is normally performed by the public network to ensure that the call being
placed has a valid billing number. In systems with a flexible Calling Number Provisioning, the
network can determine if the call is for a valid billing number. Based on this, it can either place
or reject the call, rather than completing the call and billing it to the default LDN.
Number Privacy allows the caller to prevent the public network from delivering the Calling
Number to the called party on a per-call basis. Service subscribers can request that the number
be presented or not, as a default from the public network. Subscribers can also change default
settings. If a public telco service allows changes to be made, then a user can enter change a
code to the setting for that call after selecting a trunk group.
Number Delivery sends the calling number with the call setup message, if that number is not
blocked. The Strata DK handles the number the same way that ANI information from T1
trunks is handled. For instance, the number can display on the called telephone's LCD, or it
can be used by TAPI interfaces, or it can be recorded in SMDR data records.
Name Delivery will not be supported in this release, due to the lack of a common
Note
specification for the public ISDN network.

Least Cost Routing (LCR)

Different route plans may be designed to automatically place outgoing calls over the most cost-
efficient routes. See the table below for LCR capacities.
Three different LCR time schedules with their own priority schedules can be set up for the
business day. Stations can be grouped into one of eight LCR classes, each with its own routing
priority. Selected station users may have priority use of a line, even when the route with the lowest
cost is not available. LCR is compatible with ABR.
