336 Chapter 36 Private networking: DPNSS network services (UK only)
A typical Private Number, using a private access code and dialed from another site on the network,
appears below.
Private Access
Code
6
In this networking example, a private network is formed when several systems are connected
through a Meridian M1 and a terminating BCM system. Each site has its own HLC and a range of
DNs. Figure 104
Calls are dialed and identified to the system as follows:
• To reach a telephone inside the Private Network, at the BCM site, the user dials the DN of
choice.
• To reach a telephone inside the Private Network, from another site, the user dials HLC + DN.
• To reach a telephone outside the Private Network, the user dials an Access Code + HLC + DN
Each node has its own destination (dest) codes which includes the appropriate access and HLC
codes to route the call appropriately.
Table 71 shows examples of the construction of numbers used when dialing within the example
network. Note that 6 is the Private Access code.
