    Issue 2 DEFINITY Enterprise Communication Server Release 9 Installation and Maintenance for Survivable Remote EPN 555-233-121 November 2000 About This Document About This Document The Survivable Remote EPN (SREPN) is a disaster recovery operation rather than an additional reliability option. As such, the SREPN, if administered properly, provides phone service to users on the remote EPN when the link to the main R9r processor fails or is broken, or when the R9r processor or center stage fails.
