I-27 Inter-PBX Coordinated Station Numbering Plan - PRI
Interactions
1. LEAST COST ROUTING (LCR) - 3/6-DIGIT PRI [L-31]: The first codes for INTER-PBX
COORDINATED STATION NUMBERING calls must be distinct from the assigned LCR access codes.
INTER-PBX COORDINATED STATION NUMBERING calls are routed independently of EPN calls.
The routing patterns are shared by both LCR and INTER-PBX COORDINATED STATION
NUMBERING.
2. UNIFORM NUMBERING PLAN (UNP) [U-4]: INTER-PBX COORDINATED STATION
NUMBERING - PRI can be integrated with the EPN UNIFORM NUMBERING PLAN calls. For
example, a five-digit coordinated telephone number may also be the same as the last five digits of a seven-
digit UNP number.
