CALEA System Security and Integrity (SSI) Plan — CLEC SS7 / facilities.
|
|
|
|
Tailored variant of the generic CALEA SSI plan for a Competitive Local
|
|
Exchange Carrier that operates its own TDM / SS7 / SIGTRAN switching
|
|
infrastructure. The lawful-intercept method is provisioned at the Class 5
|
|
softswitch and at the SS7 / SIGTRAN STPs using the industry-standard
|
|
ATIS J-STD-025 interface. CALEA scope covers both local-exchange
|
|
switching and resold access transport.
