We also recommend that you print the file for comparison with previous history files and entry into your maintenance log.
Using Loopbacks Using Loopbacks 179 Loopbacks allow you to check circuit continuity between one point and another. You should use the PathBuilder S330/S310 loopback feature to check continuity to the nearest point first, and if the circuit is valid to that point, then loop to the next point. If a circuit has been compromised, isolating the problem between two points should help you identify and resolve the problem.

B PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW This chapter describes the operation and data flow for each of the SuperStack® II PathBuilder® S330 and S310 WAN access switch (PathBuilder S330/S310) modules and supported applications.
210 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW enabled, an early packet discard operation is performed to check if the cell needs to be discarded. Counters for cells received and cells dropped are also updated, depending on the operation. CTX Output Queues and Memory Partition The CTX is an output buffered switch, with a bus capacity of 400Mbits total. It can store 64K cells. The CTX terminates three Utopia buses, each capable of terminating an OC3/STM-1 payload.
CTX Switch 211 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. CBR traffic (voice and video) requires the least latency during transmission, while VBR traffic (email and FTP) is more tolerable to delays but more sensitive to errors.
212 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW VPI and VCI Ranges As explained earlier in this chapter, address translation is performed in the CTX. For VP connections, the full 8 bits of the VPI is looked up, so up to 256 VP connections are supported per port. For VC connections, only two LSB VPI bits and 8 LSB VCI bits are considered. So, for VC connections, VPs 0 through 3 and VCs 1 through 255 are the only ones supported.
OC3/STM-1 Port 213 n The cells are passed to a line HEC framer to synchronize to the line speed. n The T1/E1 chip adds the T1/E1 overhead and converts the digital data into a bipolar format suitable for transmission. An 8 KHz clock is extracted from the T1/E1 clock (on all T1’s/E1s) and is used for system synchronization. The system uses this clock or other clocks to generate a stable 8 KHz clock for all other modules and interfaces.
214 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW Serial Interface The serial interface is designed to interconnect frame-based devices/networks and cell-based ATM devices/networks. The PathBuilder S330/S310 provides a single serial interface that can be configured as DTE or DCE and, with different cable adapters, can support V.35/RS-449/RS-530/X.21 interface to routers. The PathBuilder S330/S310 can perform cell-to-frame as well as frame-to-cell conversion.
Serial Interface 215 When connecting the PathBuilder S330/S310 to an ATM network, verify that the PVC mapping for in and out ports is defined for proper operation. (See Figure 153.) Figure 153 PathBuilder S330/S310 to ATM PVC PathBuilder S330/S310 Frame In PathBuilder S330/S310 VP 0 VC 50 Out DLCI 50 ATM VP 0 VC 50 VP 3 VC 45 Out VP 3 VC 45 In It is also important to select the proper traffic contract from the ATM switch/service provider.
216 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW DXI protocol defines an open interface between the router and the Data Service Unit. The Data Service Unit off-loads cell encapsulation services from the Brouter. This will allow your current brouter to support ATM, simply by supporting V.35 and High-level Data Link Control (HDLC). 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 156.
Serial Interface 217 Through ATM DXI, the DCE allows the DTE to participate in an ATM network. (See Figure 157.
218 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW 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. (See Figure 158 on the previous page.) Figure 159 shows the applications for DXI. Figure 159 DXI Applications V.
Serial Interface 219 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 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. The TTC Firebird V.35 frame relay interface provides that simple capability.
220 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW These interworking features are described in FRF.8 and FRF.5 respectively. The major difference between these two features is that there is no FR-SSCS function required for Service Interworking. The following sections describe the details of these two interworking functions as well as the features provided by the PathBuilder S330/S310.
Serial Interface n 221 The PathBuilder S330/S310 sitting in the middle performs all the required translation and management functions between these two networks, implementing the stacks as indicated in Figure 162 and performing the following key functions: n Translating from Q.922 Frame to ATM AAL5 PDU and from ATM AAL5 PDU to Q.
222 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW n The PathBuilder S330/S310 performs all the required translation and management functions between these two networks, implementing the stacks as indicated in Figure 162 and performing the following key functions: n n Supporting 2-octet—not 3-octet or 4-octet—FR header (10-bit DLCI) n Allowing you to configure DLCI to VPI/VCI mapping n Ethernet Interface Translating from Q.
Ethernet Interface Bridge Operation 223 n The SAR will then assemble the cells belonging to the connections specified for it. n When the cells are assembled, the CPU is given confirmation, and the bridge function of the CPU examines the packet header, removes the encapsulation, and—after learning the address and updating the bridge table—forwards the packet to the proper destination. n The pointer of the packet to be forwarded is placed in the transmit queue of the Ethernet port.
224 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW Spanning Tree Spanning Tree (IEEE 802.1d) is a technique that detects loops in a network and logically blocks the redundant paths, ensuring that only one route exists between any two LANs. It eliminates the duplication of packets and provides fault tolerance for resilient networks.
Ethernet Interface 225 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, each set of one Ethernet port and its associated ATM VCs is treated as one bridge entity. The STAP module runs a separate instance for each bridge entity.
226 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW Figure 163 Virtual Circuit Scheme Transmission Path Virtual Circuit { VPI 1 VCI 1 (Transmit) VCI 1 (Receive) VPI 2 VCIs { VPI 3 VCIs { Figure 164 illustrates this on a network using PathBuilder S330s. Suppose workstation 1 on LAN AA wants to send data to workstation 2 on LAN BB. It transmits Ethernet packets which include its MAC address and that of workstation 2.
Ethernet Interface 227 The aggregate of VPIs/VCIs assigned to the Ethernet connection of the PathBuilder S330/S310 is referred to as a bridge. Since the PathBuilder S330/S310 reads and stores MAC addresses and associated VPIs/VCIs as described above, the bridge is called a learning bridge. Each learning bridge of the PathBuilder S330/S310 has a separate forwarding table containing the MAC address to VPI/VCI associations. When a learned entry is stored in a forwarding table, it is time tagged.
228 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW 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 166. 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).

230 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW Figure 168 shows three PathBuilder S330s 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 to another port on another PathBuilder S330.
CBR Module 231 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. See Figure 168. The ATM network will transport the cells according to the VPI/VCI headers.
232 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW 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 DSO and ABCD signaling components using structured mode or tunneled through the ATM network using unstructured mode. Structured mode allows DSO mid span drop and insert or grooming.
CBR Module Structured DS1 233 Implement the structured service if you require DS0 midspan drop-and-insert. (See Figure 170.) Figure 170 CBR Structured DS1 - Drop and Insert B A DS0 = 5 DS0 DS1 DS0 = 5 VP0/VC35 C ATM Network Structured CBR traffic DS0 = 5 PathBuilder S330/S310 Channel Bank Public Switched Telephone Network A Channel bank converts analog to T1; putting channel on DS0 5.
234 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW 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 172.
CBR Module 235 These frames are then followed by the ABCD bits of each active DS0. Two DS0’s ABCD bits are provided in each byte after the last DS0 group. Figure 174 shows an example of three DS0s and their ABCD bits sent in a structured encapsulation. Figure 174 Multiframe Structure for 3x64kbit/s DS1 with CAS AAL1 Pointer First Transported Octet of Multiframe Second Transported Octet of Multiframe First 125 µsec Frame of Multiframe for DS1 Second 125 µsec Frame of Multiframe for DS1 ...
236 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW 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.
CBR Module Unstructured DS1 237 Implement unstructured DS1 service when you want DS1 tunneling through an ATM system. DS1 tunneling allows an entire DS1 frame, including framing bits, to travel across an ATM network. See Figure 176.
238 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW Figure 177 depicts the effects of structured versus unstructured service on the DS1 framing.
CBR Module 239 Figure 178 illustrates point-to-point video conferencing between three PathBuilder S330 switches (#1111, #2222, and #3333). Table 33, Table 34, and Table 35 list possible routing tables for the three units. Figure 178 Point-to-Point Video Conferencing Video/Audio Codec V.35/ RS-449/ RS-530/ X.21 Video/Audio Codec V.35/ RS-449/ RS-530/ X.21 RS-366 PBS330 #1111 Video/Audio Codec V.35/ RS-449/ RS-530/ X.
240 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW Multi-point Video Conferencing In multi-point video conferencing an MCU (Multi Conference Unit) device is connected to one T1-DSX/E1 CBR port of a PathBuilder S600 or PathBuilder S330/S310 at the central site. The remote PathBuilder S330/S310 switches communicate with each other via their serial (V.35/RS-366) ports, as they do in point-to-point video conferencing.
Voice Compression Module 241 To set up multi-point video conferencing, you build virtual circuits (defined by transmit and receive vpi/vci combinations) between the remote units and between the remote units and the central unit. The remote units can use the same vpi/vci to communicate with the central unit (one at a time), or you can allocate different channels and set up separate virtual connections to each remote unit.
242 APPENDIX B: PATHBUILDER S330/S310 MODULE AND APPLICATION OVERVIEW Supported Voice Compression Features The VCM supports the following features: n G.729A, G.726, and G.711 compression algorithms—You must configure the voice coding (compression) for each DS0 channel. The decompression runs in the same mode as the compression. In addition, the remote end must be set up to run the same mode as the local end—there is no auto-switching for the voice compression mode.
