ABSTRACT: GR-581 replaces TR-TSY-000581, Issue 1, but contains NO TECHNICAL CHANGES from that original document. It has been issued strictly to conform with the new Telcordia Technologies document format and GR process, and carries a new issue number and date.

It is sometimes advantageous for a telephone subscriber to provide others with a telephone number other than his/her Directory Number DN). Such action could allow others to call at little or no cost. The Remote Call Forwarding (RCF) feature provides for all calls to a DN to be permanently forwarded, through the Direct Distance Dialing (DDD) network, to a remote DN. RCF is similar to Call Forwarding Variable (CFV), which is described in GR-580-CORE. The RCF differences are as follows:

• The forwarding is always activated
• No physical telephone is associated with the RCF base DN
• Simultaneous calls (up to a limit) may be active between the base switching office and the RCF remote DN
• RCF calls may require gain
• The forwarded-to number cannot be changed by direct customer action
