Define the dialing plan information 319
Follow the steps in Procedure 48 "Defining the local Dialing plan" (page
322) to define the local dialing plan.
Non-Gatekeeper-resolved (local) dialing plan
The local dialing plan consists of a number of VoIPdestination nodes, such
as IP Trunk3.01 (and later) and ITG Trunk 2.x nodes, and one or more
dialing plan entries for each destination node.
If the destination node is also provisioned as a node in TM 3.1, select the
destination node and the protocol is provided. If the destination node is not
provisioned in TM 3.1, manually enter the destination node and select the
node capability. For each destination node, select whether QoS monitoring
is enabled and the levelof QoS required. Qos monitoring is only available
on IP Trunk3.01 (and later) and ITG Trunk 2.x nodes. Enter the destination
nodes for all destination nodes in the VoIPnetwork.
The following sections provide information on the node protocol to use, the
QoS values to enter, and the dialing plan type to enter.
Destination node protocol
The dialing plan information in TM 3.1 must correspond with what is
provisioned on the far end. The node capability must match what is
provisioned in TM 3.1 and on the Meridian 1/CS 1000M. For example, the
ESN5 feature works optimally if all endpoints contacting an ESN5 node
have SL1ESN5 provisioned as the node protocol. Foe more information,
see "ESN5 network signaling" (page 231).
If the far end is using IP Trunk 3.01 (and later) or ITG Trunk2.x software,
and is a Small System, the possible protocols are SL1 and SL1ESN5. If the
far end is using IP Trunk3.01 (and later) or ITG Trunk 2.x software, and is a
Large System, the possible protocols are SL1, SL1ESN5, and QSIG.
Quality of Service
Quality of Service monitoring allows new calls to fall back to alternate
circuit-switched trunk routes such as PRI trunk when the IP network QoS
levelfalls below the configured threshold. Ifthe QoS is disabled, then the IP
Trunk3.01 (and later) node attempts tomake new calls over the IP network,
whether the IP network status is good or poor.
If the far end is an ITG 2.x Trunk node or an IP Trunk3.01 (and later)
node and all calls to that far end are going to be locally resolvedusing the
provisioned dialing plan, then QoS can be used. If QoS is selected, then a
level of Qos must also be selected. The level of QoS is based on a model
developed by the ITU-T which is explained in the section "E-Model" (page
73). The default is value for QoS is 3 which is considered "Good", according
to the E-model.
