Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet- Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet- Drafts as reference material or to cite them other than as "work in progress."

Abbreviations CO - Central Office FXO - Foreign Exchange Office CPE - Customer Premises Equipment SDMF - Single Data Message Format MDMF - Multiple Data Message Format 1. Abstract This document describes the events and signals helpful for signaling between CO and FXO at CPE. It is intended to satisfy the requirements in section 12 of the Megaco RFC 3015/H.248 document. 2. Conventions used in this document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC-2119. 3. FXO Package Package Name: FXO handling package PackageID: fxo (0xIANA) Description: This package handles various events and signals on FXO. Version: 1 Kalubandi & Patil [Page 1] INTERNET DRAFT MEGACO/H.248 FXO package February 2002 Extends: None 3.1 Properties None 3.2 Events 3.2.1 Detect Ring EventID: ri (0x????) Generated when a ring is detected on the FXO. EventsDescriptor parameters: None ObservedEventsDescriptor parameters: Caller ID ParameterID: cid (0x????) Type: String, returned as quoted string which MAY be empty. The string could be either in SDMF or MDMF format. If Caller Id information could not be detected for any reason an empty string SHALL be returned and SHALL NOT generate an Error Descriptor. 3.2.2 Remote hangup EventID: rh (0x????) Generated when remote party going on-hook is detected at FXO using end of call signal, which MAY vary depending on local CO. This event abstracts the actual signaling method (depending on Loop-start or Ground-start signaling techniques) used by CO to indicate remote party going on-hook to FXO. EventsDescriptor parameters: None ObservedEventsDescriptor parameters: None 3.3 Signals 3.3.1 Send off-hook SignalID: of (0x????) Sends off-hook through FXO to CO. Kalubandi & Patil [Page 2] INTERNET DRAFT MEGACO/H.248 FXO package February 2002 Signal Type: Brief Duration: Provisioned Additional Parameters: None 3.3.2 Send on-hook SignalID: on (0x????) Sends on-hook through FXO to CO. Signal Type: Brief Duration: Provisioned Additional Parameters: None 3.3.3 Send flash-hook SignalID: fl (0x????) Sends flash-hook through FXO to CO. Signal Type: Brief Duration: Provisioned Additional Parameters: None 3.4 Statistics None 3.5 Procedures None 4. FXO Enhanced Package Package Name: FXO enhanced handling package PackageID: fxoen (0xIANA) Description: This package handles sending digits on FXO useful in enblock dialing. Version: 1 Extends: None 4.1 Properties None Kalubandi & Patil [Page 3] INTERNET DRAFT MEGACO/H.248 FXO package February 2002 4.2 Events None 4.3 Signals 4.3.1 Send digits SignalID: sd (0x????) Sends the digits presented by MGC on FXO. Signal Type: Brief Duration: Provisioned (for single digit) Additional Parameters: DigitString ParameterID: ds (0x????) Type: String of digits which are to be sent. 4.4 Statistics None 4.5 Procedures None 4.
