• you create access codes that are routed out on auto-answer
lines connected to the other sites (
Access Codes
and
Call
Routing
)
• a telephone can be reached using the access code and the
telephone number, regardless of where the call originates
in the network
Calls routed over private networks using UDP require a
private DN length, since each node requires an identification
code in the dialing string, which makes the DN length different
than for a public-routed call.
If you are networked using UDP:
• you indicate a private DN length, which is the number of
digits required to access sets in the system (
System
Programming/Dialing Plan/Private network
)
• each system has a unique location code (
System
Programming/Dialing Plan/Private network
)
• you indicate that you are using a UDP dialing plan
(
System Programming/Dialing Plan/Private
network
)
• you set up private access codes (
Access codes/Private
access codes
)
• a telephone in another node is accessed using the access
codes, the location code, and the telephone DN.
Any programming for routing and access codes should be
carefully planned using the tables supplied with the
Programming Record . The settings for routing and destination
codes are fully explained in Services on page 381.
Note: Network access codes must not conflict with access
codes used for other purposes.
