Nortel Networks NN43001-563 Congure dialing plans within the corporate network

230 Install and conﬁgure IP Trunk3.01 (and later) node

interface MACaddress; for example: 00:60:38:01:06:C6. To ﬁnd the ELAN

network interface MAC address, referto the IP Trunk 3.01 (and later)

Installation Summary Sheet. The ELAN network interface MAC address

is labeled on the IP trunk card faceplate as the "motherboard Ethernet

address." Alternatively,use the ITG shell command "ifShow" to displaythe

Ethernet address for lnIsa (unit number 0).

Conﬁgure dialing plans within the corporate network

Conﬁgure the dialing plan by programming LDs 86, 87, and90 as required.

Conﬁgure the Meridian 1/CS 1000M ESN by creating or modifying data

blocks in LDs 86, 87, and 90, as required. The Meridian 1/CS 1000M and

TM 3.1 IP Trunk3.01 (and later) dialing plan information must correspond.

When adding IP Trunk 3.01 (and later) TIE trunks to an existing ESN,

a common practice is to create a new Route List Block (RLB) forESN

translations that are to be routed by the IP Trunk3.01 (and later) network.

Insert the new IP Trunk3.01 (and later) route ahead of the existing alternate

routes for circuit-switched facilities,which are therefore shifted to the next

higher entry number. Increment the ISET (initial set) if Call-Back Queueing

or Expensive Route Warning tone are being used.

route For the IP Trunk3.01 (and later) trunk route entry in the Route List Block

(RLB), enter RRA at the Step Back on Congestion (SBOC) prompt. This

enables fallback to alternate circuit-switched trunk routes in the following

situations:

•due to network QoS falling below the deﬁned threshold forthe IP Trunk

3.01 (and later) node

•when there are no ports available at the destination IP Trunk3.01 (and

later) node

Based on site data, if fallback routing occurs frequently and consistently

for a data network during speciﬁc busy hours (for example, every Monday

10-11am, Tuesday2-3pm), these hours should be excluded from the RLB

to maintain a high QoS for voice services. By not offering voice trafﬁc to a

data network during known peak trafﬁc hours, the incidence of conversation

with marginal QoS can be minimized.
