Private networking with DPNSS

(International only)

DPNSS supports the Universal Dialing Plan (UDP), an international standard for sending and

receiving private numbers over networks. The UDP requires that a dialing number include the

following:

• a Private Access Code, programmed into the system as part of the destination code table to

prevent conflicts with the internal numbering system. (Access Codes)

• a Home Location Code (HLC) assigned to each PBX system, and configured as part of the

destination code (a maximum of seven digits). For each HLC, a destination code must be

programmed in the system. (Configuration > Telephony > Dialing Plan > Private

Networking)

• a Directory Number (DN) assigned to each extension as a line appearance. The DN appears as

the last string segment in a dialed number. In the number 244-1111, 1111 is the DN.

A typical Private Number, using a private access code and dialed from another site on the network,

appears below.

In this networking example, a private network is formed when several systems are connected

through a Meridian 1 and a terminating BCM system. Each site has its own HLC and a range of

DNs. Figure 11 illustrates this example.

Table 7 shows examples of the construction of numbers used when dialing within the example

network. Note that 6 is the Private Access code.
