Section One: Introduction1.3 Equipment Performance1.3.1 ATM layerThe equipment will be fully compatible with the showed on the figure 1ofthe ANSI T1.413-19981. Adaptation layerThe modem will implement the adaptation layer AAL5, as requested by therecommendation ITU I.363.52. VCsSupport for non-zero VPIs is limit to PVCs only.The full VPI range(0~4095)is supported.The full VCI range(1~65536) is supported. Low-numberedVCIs on VPI0 are looked up.3. Service classThe modem will support : CBR,UBR,rt-VBR,nrt-VBR4. OAM streamsThe modem supports OAM F5 stream.5. ATM signaling & ILMIThe modem supports ATM Formun UNI 3.0,3.1,UNI4.0& IISP signalingbased on UNI3.0 or UNI3.1 using SSCOP as a data transport.Theimplementation of ILMI is based on the ATM Forum's ILMI v4.0 specification.1.3.2 Protocols1. BridgeIt provides a transparent and a spanning-tree bridge.2. RFC 1483 bridgedThe RFC in use is the 2684, , the 1483 and 2684 are admitted for LLCencapsulation and VC multiplexing for bridged traffic.4
