You must purchase and install these keycodes before you can create any of the networks described
in this chapter. Consult with your Nortel distributor to ensure you order the correct keycodes for
the type of network you want to create.
Remote access to the network
Authorized users can access TIE lines, central office lines, and BCM features from outside the
system. Remote users accessing a private network configured over a large geographical area, can
potentially also place long-distance calls through the network and avoid toll charges. Also refer to
“Call security and remote access” on page 415.
Other programming that affects private networking
Besides the line programming, these links connect to other programming that affects or is affected
by private networks.

Types of private networks
There are several ways you can create private networks. Configuration can be based on such things
as cost of trunks, proximity of network nodes, size of the private network, and business
requirements for communications.
VoIP-based networking also requires an understanding of IP features such as codecs, jitter buffers,
Quality of Service (QoS) function, and silence suppression.
Note: You cannot program a Private DISA DN or Private Auto DN to a VoIP
trunk, as they act as auto-answer trunks from one private network to the next.
However, you can configure VoIP line pools with remote access packages so
that callers can access telephones or the local PSTN on remote nodes on a
tandemed network that use VoIP trunks between systems.
