Alcatel-Lucent 3600 manual T E C H N I C A L S U M M A R Y, Card Variants, ATM Service Adaptation

T E C H N I C A L S U M M A R Y

Card Variants

There are 8 variants based on:

•Primary rate interface (T1 or E1)

•AAL type (AAL1 or AAL1/AAL5)

•System backplane bandwidth (4 Mb/s or 16 Mb/s)

•EMC compliance

ATM Service Adaptation

•AAL1 and AAL5

•Selectable on a DS0 basis for channelized user-side interfaces (e.g., T1/E1)

AAL1 Adaptation and CES

•AAL1 or AAL1/AAL5

•Adapts CBR data and associated signaling (n*64 kb/s) to AAL1 VCs over an ATM network, in accordance with AF-SAA- 0032.000 and GR-1113- CORE

•DS0s

¬Supports up to 84 for T1 interfaces

¬Supports up to 104 for E1 interfaces

¬Multiple DS0 CESs can be transmitted over the same VC

¬Voice (LGS) and data (V.35) DS0s with a common desti- nation can be transmitted together

•Configurable signaling multi- frame size: 16 or 24 frames

•Supports voice signaling with robbed-bit signaling and channel associated signaling

•Received cell delay variation tolerance is user defined per VC

•Transmit cell level is user defined per VC from n to 47, in one byte increments, where n is the number of DS0s in the VC

AAL5 Adaptation and

HDLC Services

•AAL1/AAL5

•Transports HDLC-formatted traffic over an ATM network

•Transparently adapts streams of HDLC frames into AAL5 VCs

•Interworks and adapts streams of frame relay HDLC frames into AAL5 VCs

•Supports up to 3,968 Kb/s of HDLC-formatted traffic

Interworking Mode

•Supports service interworking mode (translates frame relay into ATM, for transmission across an ATM network to ATM devices)

•Supports network interworking mode (transports frame relay across an ATM network to another frame relay network)

•Compliant with FRF.5 and FRF.8 using AAL5 and non real-time variable bit rate (nrt-VBR) or unspecified bit rate (UBR)

Data Link Connections (DLCs)

•Supports up to 250 DLCs per stream

•Supports up to 1,024 DLCs per card

Connection Admission Control (CAC)

•Static and dynamic

•Based on:

¬Peak information rate (PIR)

¬Sustained information rate (SIR)

¬Minimum information rate (MIR)

ATM Traffic Management

•Configurable service categories

¬AAL1 VCs

¬CBR

¬AAL5 VCs

¬nrt-VBR, with VC traffic management

¬nrt-VBR, with virtual path (VP) traffic management

¬UBR, with VC traffic management

¬UBR, with VP traffic management

Frame Relay Traffic

Management

•Configurable class of service parameters

¬Committed information rate (CIR)

¬Committed burst size (Bc)

¬Excess burst size (Be)

•Configurable congestion thresholds

¬Absolute congestion threshold (ACT)

¬Severe congestion threshold (SCT)

¬Mild congestion threshold (MCT)

•Supports link management protocols

¬Local management interface (LMI): user, network and network extended

¬ITU-T Q.933 Annex A: user, network and bidirectional

¬ANSI T1.617 Annex D: user, network and bidirectional

Interfaces

•Single logical ATM interface, user programmable for up to four T1 or E1 interfaces

•Supports ATM Forum IMA standard AF-PHY-0086.000

•4-port T1 interface, user program- mable for DS1 or DSX-1 operation

•4-port E1 interface, compliant with ITU-T G.703, 75 Ω or 120 Ω

•Transmit timing obtained from node system clock or network

•ATM Forum UNI 3.1
