If the queue is congested and early packet discard is enabled, an early packet discard operation is performed to check if the cell needs to be discarded.
Page 245 CTX Switch The default memory conﬁguration uses all available memory. In order to reallocate memory to a given queue, you must ﬁrst deallocate it from one of the other queues. Since the CTX is output-buffered, and if the WAN trunk has the lowest speed (for nxT1/E1), the WAN trunk should take up most of the buffer.

See “Conﬁguring Virtual Circuits” in Chapter 4, for details about setting up virtual circuits.
Page 247: Oc3/Stm-1 Port
OC3/STM-1 Port The IMA logic spreads the cells in a particular group across the physical lines and adds the IMA overhead functions. The cells are passed to a line HEC framer to synchronize to the line speed. The T1/E1 chip adds the T1/E1 overhead and converts the digital data into a bipolar format suitable for transmission.
Page 248: Serial Interface
B: P S330/S310 M PPENDIX UILDER ODULE AND PPLICATION VERVIEW The E3 UNI module performs the following key functions: Performs ATM to physical layer mapping and adds PLCP according to UNI 3.0 Performs peak trafﬁc shaping on the transmit (14 bulk shapers) Serial Interface The serial interface is designed to interconnect frame-based devices/networks and cell-based ATM devices/networks.

Page 250 B: P S330/S310 M PPENDIX UILDER ODULE AND PPLICATION VERVIEW The DXI protocol itself is based on HDLC and provides the mapping within the HDLC frame to place the router data on an appropriate VC. (See Figure 172.) Figure 172 DXI Protocol Enabling Transmission Between ATM Network and DXI Device Synchronous V.35 RS 449/422, X.21, RS-530...
Page 251 Serial Interface Figure 173 DCE Allows DTE to Participate in ATM Network through ATM DXI DTE SDU DTE SDU AAL 5 CPCS DXI Data Link AAL 5 SAR DXI Data Link DXI Physical DXI Physical UNI Physical DXI mode 1A is designed to allow legacy routers to use frame-based transmission to transmit an ATM network to the DXI mode 1A device (PathBuilder S330/S310 serial interface), which then will perform SAR and AAL5 mapping to an ATM PVC.
Page 252 B: P S330/S310 M PPENDIX UILDER ODULE AND PPLICATION VERVIEW DXI protocol frame is an HDLC LLC1 frame similar to PPP protocol. Mode 1A supports an AAL5 transit encapsulation. In terms of the brouter, it is easier to implement DXI protocol, since it only requires the brouter to encapsulate the SDU. DXI protocol supports up to 1023 connections and up to 9232 octets of payload.
Page 253: Hdlc/Sdlc Mode
Serial Interface HDLC/SDLC Mode Transparent HDLC mode is used for point-to-point HDLC connections across the ATM network. No service-based encapsulation other than AAL5 is needed. All packets are terminated and SAR’d (processed via segmentation and relay) to a single VP/VC in the ATM network. Transparent mode functionality is best implemented with a PRBS type of pattern included in a sequence of frames.
Page 254: Frame Relay Mode
B: P S330/S310 M PPENDIX UILDER ODULE AND PPLICATION VERVIEW Frame Relay Mode Frame relay mode is used to terminate a frame relay router, across the ATM network, for example. This protocol mode converts the frame relay DLCI to a VP/VC ATM connection.
Page 255 Serial Interface The interworking scheme shown in Figure 177 works as follows: The application on the frame DTE passes its data through Q.922 core service with the assumption that there is an end-to-end pipe to carry its data from its end to the other DTE at the far end.
Page 256: Ethernet Interface (10Base-T Or 10/100Base-T)
B: P S330/S310 M PPENDIX UILDER ODULE AND PPLICATION VERVIEW In the interworking scheme shown in Figure 178, a Frame Relay DTE communicates with the other Frame Relay DTEs through an ATM network. Note that FR-SSCS is used in this conﬁguration. This interworking scheme works as follows: The Frame Relay DTE at either end works exactly the same way as the Frame Relay DTE in the Service Interworking conﬁguration: it passes its data through...
Page 257: Bridge Operation
Ethernet Interface (10BASE-T or 10/100BASE-T) The SAR contains 15 trafﬁc shapers, each of which can be programmed for sustained cell rate of transmission (SCR), peak cell rate (PCR), and maximum burst size (MBS). The trafﬁc shapers work as follows: The packet is segmented using a dual leaky buffer algorithm, whereby the cells are transmitted from each connection in the shaper at an average rate until the bucket of token ﬁlls up (a token is given to the connection at an average rate if it has no cells to transmit at that moment).
Page 258: Filtering
B: P S330/S310 M PPENDIX UILDER ODULE AND PPLICATION VERVIEW Filtering The ﬁrst bridging operation determines if the packet is to be processed and transmitted across the bridge or ﬁltered out based on the list of protocols and addresses input as part of the PathBuilder S330/S310 conﬁguration. Filtering gives you control over who communicates with whom in the network.
Page 259: Spanning Tree Instances
Ethernet Interface (10BASE-T or 10/100BASE-T) Spanning Tree Instances The spanning tree logic supports a maximum of 255 physical and virtual ports, thereby allowing a maximum of 254 ATM VCs. (One Ethernet port is required be set aside for other purposes.) For the purpose of spanning tree operation, the Ethernet port and its associated ATM VCs is treated as one bridge entity.

Suppose workstation 1 on LAN AA wants to send data to workstation 2 on LAN BB.
Page 261 Ethernet Interface (10BASE-T or 10/100BASE-T) The aggregate of VPIs/VCIs assigned to the Ethernet connection of the PathBuilder S330/S310 switch is referred to as a bridge. Since the switch reads and stores MAC addresses and associated VPIs/VCIs as described above, the bridge is called a learning bridge.
Page 262: Segmentation
B: P S330/S310 M PPENDIX UILDER ODULE AND PPLICATION VERVIEW Segmentation Once it is determined that a packet should go across the bridge, the packet is encapsulated per RFC 1483 and a pad and trailer conforming to AAL5 (ATM Adaption Layer 5) is added at the end of the packet. See Figure 182. The trailer is ﬁxed at eight bytes and contains information such as the new length of the packet and cyclic redundancy check bytes (CRC facilitates error checking at the receive end).

Page 264 B: P S330/S310 M PPENDIX UILDER ODULE AND PPLICATION VERVIEW Figure 184 shows three PathBuilder S330 switches connected through a carrier ATM network or a private switch. The ATM switch or network should be conﬁgured with Permanent Virtual Circuits (PVCs) connecting one LAN or Ethernet port on one PathBuilder S330 switch to another port on another PathBuilder S330 switch.
Page 265 CBR Module Each PVC represents the logical circuit being used to connect one PathBuilder S330/S310 port to a remote PathBuilder S330/S310 port. Once you have entered all PVCs, the bridge will learn the network addresses for the local and remote sites and start bridging packets to the correct destination by segmenting the packets into cells which are destined to a remote PathBuilder S330/S310 port.
Page 266 B: P S330/S310 M PPENDIX UILDER ODULE AND PPLICATION VERVIEW The T1-DSX/E1 inputs can be either ESF, SF, or no-framing using B8ZS or AMI. In accordance with the ATM Forum’s Circuit Emulation Service (CES) speciﬁcations, the received frame can be broken up into its DS0 and ABCD signaling components using structured mode or tunneled through the ATM network using unstructured mode.

B: P S330/S310 M PPENDIX UILDER ODULE AND PPLICATION VERVIEW Drop-and-Insert DS0 channels can be allowed to transit the entire path, providing DS0 to DS0 connectivity between end locations. Structured DS0s can also be groomed to be combined through an ATM network, thereby allowing end-to-end DS0 switching, as shown in Figure 188.

Page 270: Unstructured Ds1
B: P S330/S310 M PPENDIX UILDER ODULE AND PPLICATION VERVIEW Structured data DS0s allow for clear channel signaling (CCS). As opposed to CAS, in which signaling is done on all channels, in clear channel signaling (CCS) one channel is used to signal for the other channels. The PathBuilder S330/S310 software can also monitor a full 8-bit pattern on a DS0 to determine circuit activity.
