中文名称 ATM上的语音和多媒体 - 使用AAL2的环路仿真业务
英文名称 Voice and Multimedia Over ATM - Loop Emulation Service Using AAL2
发布日期 2000-07-01
工作组 Voice & Telephony over ATM
摘要 This specification describes the procedures and signaling required to support the efficient
transport of voiceband services across an ATM network between two Interworking Functions
(IWF) located respectively at a customer premises and at a service provider premises. It specifies
the use of ATM virtual circuits with AAL2 to transport bearer information and signaling. The
virtual circuits used may be PVCs, SPVCs, or SVCs. The specification supports the transport of
common channel signaling (CCS) information as well as channel associated signaling (CAS)
information.
The scope of this specification is to define the following
?The functionality of the IWFs
?Relevant control plane aspects of the Loop Emulation Service using AAL2
?Relevant user plane aspects of the Loop Emulation Service using AAL2
?Relevant management plane aspects
?Timing and synchronization requirements specific to the Loop Emulation Service
An IWF complying with this specification shall conform to the procedures described in ITU-T
Recommendation I.366.2 except where stated.
