Public And Private Received Numbers; Private Network Dialing; Setting Up Public Network Dialing - Nortel BCM50 Configuration Manual

Public and Private Received numbers

If the received number is different than the regular DN number, in the target line configuration
programming, enter the number in the Private number and/or Public number field.
Programming note: Auto-answer trunks such as PRI, T1, BRI, and VoIP trunks, use these
settings to route calls:
• DPNSS lines use the Private received number to route calls in the system.
• BRI (ETSI-QSIG), PRI (ETSI-QSIG, MCDN, DMS-100, DMS-250), and VoIP trunks route
calls on a per-call basis to either the public or private received digits.
Note: VoIP trunking does not support Auto DN/DISA DN functionality.
• BRI (ETSI-Euro, NI), PRI (ETSI-Euro, NI, 4ESS), T1 (LoopStart, E&M, DID, GroundStart),
Analog LEC (LoopStart), and DASS2 trunks route calls using the Public received number.

Private network dialing

If your BCM is part of a private network, you have a choice of dialing plans. However, all BCMs
on a network must use the same type of dialing plan and have the same Private DN lengths to
ensure proper call direction. Plan these settings before you start programming for the private
network.
• UDP (Universal Dialing Plan) uses a destination code and a location code plus the set DN (that
is, 6-403-XXXX) to determine where a call gets routed. You specify a Private DN length to
allow all required digits to be dialed. Each node on the network has a unique location code.
• CDP (Coordinated Dialing Plan) uses a unique steering code that is transparent to the user and
is dialed as part of the destination set's DN (that is, 2XXXX for one node, 3XXXX for another
node, and so on) to determine where the call gets routed. Since each node on the network has a
unique code, no other routing is required.
• The Meridian system administrator, or the call control system, generates the Private Network
IDs. These IDs are unique to each node on a network. Both UDP and CDP must include this
code in programming.

Setting up public network dialing

The public network settings allows you to enter DN lengths for the networks the callers are
allowed to dial, including special numbers such as 411 and 911.
The public DN lengths table is used for all PRI calls except for those routes that use service type
Private or service type TIE with DN Type specified as Private. This table allows the BCM to
determine the length of a DN, based on the initial digits dialed.
