LERG Category/Location Type is Incorrectly Loaded as NONSWITCHING/Test or Service Position (Doc ID 1639060.1)

The rules for CLLI Entity code generation have changed recently and those changes are not included as part of the LERG loader. identified approximately 70 switches that were defined in LERG with a PS(n) entity code that were loaded as ‘NONSWITCHING’ instead of ‘SWITCHING’, which prevents them from being used as switches.

Based on the current CLLI code rules from Telcordia/iConectiv, it looks like PS(n) should map to a Network Location Category/Type of ‘SWITCHING/Packet End-Office”. Currently, all CLLIs with an entity code starting in ‘P’ that don’t end in ‘B’ or ‘D’ are mapped to ‘NONSWITCHING/Test or Service Position’, so this would require an update to the LERG rules to handle PS(n) appropriately.

From the CLLI code “Bible”:

Packet End-Office - PS(x7)
This Entity Code identifies multiple gateways that together function as an end-office switch in a voice-over-packet (VoP) network. It supports a VoP network that is comprised of both line/access and trunk gateway(s), and is associated with a call agent that provides the necessary call control functions.
Functionality is similar to a PSTN end-office switch in that all connections are done on a line-to-line, line-to-trunk, and trunk-to-line trunk-to-trunk basis. The gateway functionality can support packet-to-packet or TDM-to-packet switching fabric.
