NetPerformer Overview Verso’s NetPerformer® platform, a series of integrated multi-protocol access devices is a family of high-performance Integrated Access Devices used over public or private Frame Relay networks as well as leased-line, Satellite (SkyPerformer is a software option), ATM or IP networks. Well suited for large point-to-point and any-to-any networks, the NetPerformer uses a QoS cell based protocol called PowerCell to efficiently integrate either voice/data or data-only solutions. Also, the NetPerformer SIP software option goes further by uniting today’s distributed voice communications systems with SIP compliant VoIP softswitch and gateway platforms. This using standard protocols like SIP for the call setup, RTP for voice and T.38 for fax. The NetPerformer is intended for a broad range of applications and serve the internetworking needs of central sites, regional offices and small branch offices. Individual products utilize a common hardware platform and are available as standalone products or scalable rackmount models with data only or integrated data and voice capabilities over any networks. The feature-rich NetPerformer is able to: • Integrate SNA, legacy data, LAN traffic, toll-quality voice and fax/modem transmissions over a single

communication circuit. • Transmit and receive traffic over public or private IP, Frame Relay, ATM, leased line, ISDN, or satellite

networks. • Provide T1/E1 connectivity, including digital connections to PBXs or PSTN via T1 and E1 using CAS, CCS

(Q.SIG or ISDN) and transparent signaling. • Replace SNA leased lines with a single Frame Relay, ATM, Leased Line or IP connection. • Provide a gateway to legacy networking products: SDM-DX, SDM-FP and SDM-JFP. • Support IP/IPX/OSPF routing and bridging. • Take advantage of highly efficient data compression algorithms. • Add provision for line failure with Virtual Connections and Dial Backup functions. • Optimize line utilization with cell-based multi-protocol prioritization, Bandwidth-On-Demand and Load

Balancing. • Provide drop and insert multiplexing for data and voice over T1/E1. • Manage the impact of bursty Ethernet traffic. • Eliminate parallel voice and data networks. • Handle time-sensitive applications with reduced delays. • Ensure standards compliant interoperability with RFC-1490 (Frame Relay), RFC-1483 (ATM) and RFC-2364

(PPP over ATM) and SNMP management.

• Support standard Session Initiation Protocol (SIP) voice over IP protocol (NetPerformer SIP software option).

• Facilitate firmware upgrades through FTP or ZModem download tools. Verso’s NetPerformer with virtual-connections technology provides a complete system solution for organizations with wide area internetworking requirements. The NetPerformer maximizes bandwidth usage with high throughput levels, low overhead and minimal delays, and guarantees reliable integration of voice, fax/modem and data traffic. NetPerformer significantly cuts communications costs by cutting long-distance charges and the need for dedicated voice and data circuits in the network. NetPerformer LAN/WAN Support The NetPerformer series takes full advantage of innovative LAN/WAN capabilities: • Flexible network connections. • Efficient multiplexing of data from all sources. • Prioritization levels maintained across the network. • Routing of IP and IPX traffic; bridging of all other protocols. • End-to-end routing of cells in a meshed topology. • Dynamic rerouting in case of line failure. • Rapid, flexible and inexpensive transports of voice/fax/modem traffic without requiring network

reconfiguration. Verso’s integrated multi-protocol access devices provide an efficient means of integrating SNA, other legacy data and LAN data. They implement unique cell-based traffic prioritization and switching over virtual connections, while providing highly efficient data compression, superior traffic expediency and flexibility of the network topology. The NetPerformer merges SNA and other legacy traffic with LAN internetworks. It links Ethernet LAN networks, using routing or bridging, over dedicated or switched wide area network (WAN) services, as well as Frame Relay, ATM, ISDN or IP. Applications using diverse traffic types can be integrated as a single network, eliminating separate circuits. Reliable response time is guaranteed through prioritization of mission-critical applications, like voice and protocols such as LLC, SDLC or any user-defined protocol.

Other data-handling capabilities of the NetPerformer include: • Switching through intermediate NetPerformers using cell-relay technology. • PVC bundling to concentrate Frame Relay traffic originating from multiple FRADs or routers. • SVCs and hunt groups to maximize voice-switching capacity (standard NetPerformer only). • Bandwidth-on-demand over leased lines for managing bursty LAN traffic while keeping telecommunications

costs down. • Load balancing over leased lines, Frame Relay, ATM or IP, to provide high-speed support using multiple

circuits. • Dial backup. • Multi-protocol support. • SNA host port reduction. • High-performance data compression to improve throughput and reduce telecommunications costs. • Administrative filtering to reduce the internetwork load, based on protocols, source/destination addresses

and user-defined patterns. • PPP and BOOTP/DHCP Relay support. • Support connections to IP networks (PowerCell over IP).

LAN/WAN Interfaces • Serial ports, configurable as either user or link ports, • Ethernet LAN interfaces, either permanently installed or optionally provided through expansion slots in the

product chassis (depending on the product). • Console port. NOTE: The actual number and location of the serial ports, LAN interfaces and console port is product-dependent. For details, consult the Hardware Installation Guide for the individual product. Speeds attained on the serial ports may differ between individual NetPerformer models. In general, user ports can operate at speeds of up to 2 Mbps. Link throughput with or without data compression is product specific. Refer to table 1-1 and 1-2 of this document for details. The NetPerformer supports IP routing (RIP v1/v2 and OSPF v2) over PowerCell circuits on any networks (Frame Relay, ATM, Leased Lines, satellite or IP). The NetPerformer also support IP routing over standards Frame Relay RFC-1490, ATM RFC-1483, ATM RFC-2364, PPP or PPPoE circuits. Finally, the NetPerformer IP support also includes: IP Multicast, Network Address Translation (NAT), DHCP/BOOTP relay, DHCMP and DNS client and DiffServ/IP Precedence QoS. NetPerformer Frame Relay interfaces permit bundling of boundary Frame Relay traffic. Data originating from multiple Frame Relay Access Devices (FRADs) at the local or remote site can be concentrated onto single PVC. Returning traffic is directed to the destination devices or switched to a PVC on another NetPerformer. As a result, all Data Link Connection Identifiers (DLCIs) can be mapped and bundled over a reduced number of PVCs. Voice calls can be switched to any remote location using existing PVCs or by establishing Frame Relay SVCs on demand.

The NetPerformer supports SDLC-to-LLC2 conversion and SNA over Frame Relay through RFC-1490 PU connections (BAN/BNN). It can concentrate multiple low-speed SNA lines over a single Frame Relay circuit. In addition, cell-based prioritization combined with extensive emulation (spoofing) of the IBM SDLC protocol ensures reliable and consistent response times for mission-critical SNA applications. Network management capabilities of the NetPerformer include SNMP, TELNET remote access, FTP or ZModem firmware upgrade and direct or dialup console connection.

NetPerformer Voice Support Several NetPerformer models provide full-featured analog and digital voice support as well as voice/data integration ranging from branch to central site units. Voice support is provided on all NetPerformer products using analog and digital expansion modules. Note: Voice over PowerCell is available on all NetPerformer products (legacy and new generation), where the standard voice over IP (VoIP) SIP protocol is available, with a software option, only on the new generation NetPerformer SDM-9220, SDM-9230, SDM-9360, SDM-9380 and SDM-9585.

The NetPerformer supports connections to public and private networks, Bell Central Offices (COs), PBXs, Key Telephone System (KTS) extensions, standard telephones, fax machines and modems, and integrates their traffic with regular LAN/WAN data. It includes a variety of powerful features to ensure that voice, fax/modem and data are reliably integrated with data from other sources, efficiently transmitted across the network, and that excellent voice quality is maintained from source to destination: • Analog-to-digital conversion. • Fragmentation of the voice/fax/modem stream for reduced network latency. • High quality voice compression at 8Kbps or 6Kbps using ACELPCN algorithm. • Standard voice compression/codec supports includes G.729 and G.729a (8Kbps), G.723.1 (5.3Kbps or

6.4Kbps), G.726 (16Kbps to 48Kbps) and G.711 (64Kbps). • Fax/Modem demodulation for improved throughput of fax/modem traffic. • Variable bit rates for low bandwidth usage during silence and signaling tones. • Full support of a wide variety of interfaces and signaling types. • Cell relay for rapid transport of voice/fax/modem traffic. • Automatic voice/fax/modem prioritization. • Domain dialing for efficient inter-domain calls (not available on the SIP software version). • Voice broadcasting (not available on the SIP software version). • Autodial predefined (not available on the SIP software version) or switched line activation. • Echo cancellation. • Intelligent congestion control (voice traffic control, voice traffic re-routing, etc). Voice Interfaces The NetPerformer is equipped with voice channels, or ports, for voice/fax/modem transmission. Each channel has an analog or digital interface that supports signals from a variety of voice/fax/modem sources using industry-standard signaling methods. Input interfaces include: E&M: Ear and Mouth, used between the switching machine’s trunk circuit and an associated signaling system. FXO: Foreign Exchange Channel Unit – Office End, a loop-start signaling method used when connecting to a Central Office (CO). FXS: Foreign Exchange Channel Unit – Station End, a loop-start signaling method used when connecting to a telephone unit or facsimile machine (POTS line) or a modem or a Key Telephone System (KTS unit). T1/E1: Digital interfaces that support voice via Channel Associated Signaling (CAS) protocols, like Immediate Start and Wink Start, or via Common Channel Signaling (CCS) protocols like QSIG and ISDN-PRI. ISDN-BRI S/T: Support voice using ISDN signaling (Euro, Japanese and National). All voice channels uses DSP (Digital Signal Processor) for digitization and voice compression facilities. Echo cancellation is provided on all channels, following the CCITT G.165 standard.

Regional office SDM-8400 SDM-9400 1 (analog & digital)

SDM-9360, SDM-9380 (analog & digital) SDM-9230 (analog & digital)

Central site SDM-9530 1, SDM-9580 1 SDM-9585 (analog & digital)

The NetPerformer family supports a variety of applications. On the data side, they support SNA/SDLC with protocol emulation and port concentration, transparent point-to-point connections for HDLC and other protocols, plus LAN routing and bridging.

Note: SkyPerformer is a software option that provides satellite bandwidth optimization to the NetPerformer product line. The Enterprise Gateway SIP software option is required to provide standard VoIP using SIP. This new option can be installed/activated on the NetPerformer as well as the SkyPerformer products.

Those NetPerformers that offer voice and fax/modem integration, all support analog voice/fax/modem, and in the case of the SDM-9400 1, the SDM-9230, the SDM-9360, the SDM-9380 and the SDM-9585, digital voice/fax/modem as well. All NetPerformers also support both frame-relay switching and cell-based switching using PVCR. The customer must take into account all applications in a given network when designing NetPerformers or any similar access device into it. 1 Retired

Standard VoIP Support

The SIP project is a major development effort that Verso has taken in order to provide to our customers VoIP solutions using Session Initiated Protocol (SIP). This protocol is built on existing Internet and SMTP conventions and, because of that, is the most promising for future combination of voice and data applications. It is also an efficient VoIP protocol that provides intelligence at the edge of the network for user to take advantage for future applications like Presence, Instant Messaging, etc.

NetPerformer SIP software option

The NetPerformer with SIP is an Enterprise IP Gateway/Router that converge voice and data over IP via PPP links, Frame Relay or ATM standards protocols, PowerCell or IP/Ethernet circuits. This software option is available on the NetPerformer SDM-9360/9380(9585) as well as SDM-9220/9230 and provides the same data features but with voice transported over IP using SIP instead of PowerCell. These products support voice modules required to interface to PBX and PSTN (Analog FXS, FXO, E&M – Digital T1, E1, ISDN-PRI, ISDN-BRI and QSIG).

NetPerformer with SIP includes:

For voice:

• Standard VoIP implementation using SIP, SDP (Session Description Protocol) and SIP registration as per IETF RFC 2543 and 2327.

• Support of RTP for voice and T.38 for fax. • Support of RTCP for VoIP statistics and monitoring • QSIG supplementary services tunneling over SIP. • NetPerformer to NetPerformer calls handled without SIP Proxy (Call Manager). • NetPerformer call via Clarent Class 5 Call Manager/Command Center to another NetPerformer or a

Clarent Gateway. • Standard voice compression G729 (a), G711, G726 and G723 (low/high) as well as ACELP-CN. • CAS signaling: Immediate Start, Wink Start, Loop Start and R2 voice. • CCS signaling: QSIG and ISDN (Euro, Japanese and National). • VTR (Voice Traffic Re-routing)

For data (from the NetPerformer):

• PowerCell on dedicated or backup links, Frame Relay, ATM, ISDN and IP links. Note that Voice over IP over PowerCell is supported between NetPerformer units.

• Async/Sync PPP (Point to Point Protocol) as well as PPPoE (PPP over Ethernet) • Frame Relay RFC-1490 and switching • ATM RFC-1483, ATM-RFC-2364, PPP, FRF.8 and PowerCell. • SkyPerformer for connection over the Satellite (PowerCell, RFC-1490 or transparent) • IP routing, RIP1, RIP2, OSPF2, Multicast, DHCP/BOOTP relay, IP static, NAT and SNMP • IPX routing and bridging of the other LAN protocols • SNA SLDC, LLC, BAN and BNN local and remote conversion • HDLC, BSC, DDCMP, COP, X.25 and ASYNC legacy multiplexing • Data Compression

NetPerformer with SIP option enabled does not support the following legacy NetPerformer features:

• FP mode for inter-operation with legacy voice FRADs: SDM-FP/JFP/DX. • Direct conversion between PowerCell Voice and SIP/RTP/IP. Interoperability is achieved with back-to-

back voice conversion, e.g. E1 to E1 on two distinct NetPerformer units, one with SIP enabled, the other with PowerCell Voice.

• Transparent point-to-point voice signaling. All SIP calls are switched and transparent is non-switched.

For more details on the NetPerformer feature set, refer to the NetPerformer Datasheet located on the Verso web site at the following address: http://www.verso.com/enterprise/convergence/netperformer/index.html

Data and Voice Traffic Throughput Issues Data issues: Each NetPerformer can clock any and all of its serial ports up to 2Mbps and even up to 6Mbps in the case of the SDM-9230. But bit clocking alone does not define overall device throughput. The NetPerformer is a fast-packet access device, and as such, its basic datagrams are data cells of 96 bytes maximum obtained as a result of the NetPerformer incoming frame fragmentation process. How fast the NetPerformer can process cells is measured in Cells Per Second (CPS). Specifically, CPS measures how fast the NetPerformer can build and hand-off or receive and re-build cells and frames, regardless of prioritization schemes. The following tables 1-1 & 1-2 summarize CPS throughput for each NetPerformer product.

SkyPerformer issues: When the SkyPerformer option is enabled the NetPerformer will accept the appropriate cells or filter cells not specific to the unit. This function of analyzing and filtering cells utilizes a small amount of CPU processing. Thus SkyPerformer CPU utilization will vary depending on demod RX data rate. Please refer to the SkyPerformer design guide for more details. Voice issues: The ACELP-CN 8K/6K algorithm, the ACELP 8K/5.8K, 64K PCM and 32K ADPCM are all supported in the NetPerformer for homologation purposes, but the ACELP-CN is the algorithm of choice. One may configure either 8Kbps or 6Kbps as fixed, or configure 8K to automatically fallback to 6K during periods of congestion. Due to framing of the compressed voice, overhead must be added to the overall voice rate. For example, 8K-CN (comfort noise) really takes 12.44Kbps of bandwidth while voice is active and running on a PVCR PVC. And let us not forget the effect of comfort noise, reducing overall bandwidth utilization by around 40% when the silence suppression feature is activated.

Furthermore, one may configure the amount of buffering (single, double or triple) preferred for voice encapsulation. Double and triple buffering reduces bandwidth and CPS consumption per voice channel with an imperceptible change in voice quality. Therefore, we recommend the use of these modes.

Ensuring Reliable Delivery of Voice To ensure reliable voice packet delivery, the NetPerformer uses cell relay, which allows voice packets to traverse the network within acceptable delay parameters. Measuring Voice Quality (MOS) Although perceptions of voice quality vary by individual, the Mean Opinion Score (MOS) is a widely accepted measure of voice quality. MOS ratings provide a subjective quality score averaged over a large number of speakers, utterances and listeners. The following table indicates the value of MOS:

Score Quality 4.0 to 5.0 Toll Quality 3.0 to 4.0 Communication Quality

< 3.0 Synthetic Quality MOS Score Definitions

PCM/ADPCM PCM and ADPCM, the traditional PSTN/PTT algorithms, receive high (“toll quality”) Mean Opinion Scores. MOS of 4.4 for PCM and 4.1 for ADPCM are achieved by consuming 64Kbps bandwidth and 32Kbps bandwidth, respectively. ACELP-CN Algebraic Code-Excited Linear Prediction – Comfort Noise (ACELP-CN) grew out of years of study at various research institutions using CELP and CELP-like coders. The three main elements of ACELP-CN are: 1) LPC modeling of the vocal track, 2) sophisticated pitch extraction and coding, and 3) innovative excitation modeling and coding. Independent tests indicate the perceived quality of voice is equal to or better than the industry-standard 32Kbps ADPCM (G.726). ACELP-CN is rated with an MOS (Mean Opinion Score) of approximately 4.2. ACELP-CN allows "toll-quality" voice transmissions over Frame Relay networks

Maintaining Voice Quality Normally, complexity goes up and quality goes down as compression increases. ACELP-CN demonstrates that voice can be compressed as low as 6Kbps and still achieve near toll quality. With low-cost toll-quality voice compression algorithms and management of voice and data transmission parameters, voice quality can be maintained in high-traffic networks. NetPerformer, for example, uses six basic operating principles to ensure voice, fax and data are delivered reliably and that voice signals maintain their original quality:

• Jitter Buffers • Fragmentation • Variable Rates • Prioritization • Silence Detection and Digital Speech Interpolation Jitter Buffers The bursty nature of packet-oriented networks may result in variable delays between consecutive packets. The time difference between each arriving packet is called “jitter.” Jitter can impede the ability of the receiving end to smoothly regenerate voice. Since voice is inherently a continuous waveform, a large gap between the regenerated voice packets will result in a gobbling sound. NetPerformer employs a configurable jitter buffer (to a maximum of 255 ms) to funnel the incoming packets. This jitter buffer controls processing of packets to guarantee continuous speech output. Fragmentation In the NetPerformer, all access frame sizes delivered to the network are limited in size. • Voice: 20 to 80 bytes per frame (Depending on Voice Protocol) • Data: Maximum 96 bytes per frame • Fax: Maximum 58 bytes per frame This fragmentation minimizes end-to-end delay through network switching equipment, ensuring the timely delivery of voice and fax/modem, as well as data. Specifically, the fragmentation of data packets assures voice and fax/modem packets are not unacceptably delayed behind large data packets.

Variable Rates The NetPerformer can be configured to react to Predictive Congestion Management and/or FECN/BECN bits by varying the voice algorithm digitization rates and/or frame sizes. This is another technique used to ensure voice quality withstands network conditions. Prioritization Each input signal is configured into priority queues in NetPerformer. Voice and fax/modem signals, which are intolerant of delay, are placed in the highest-priority queue (HIGH PRIORITY class), for the most expeditious delivery to the network. Data signals are buffered into queues 1 to 8 (classes) until the higher-priority voice and fax/modem packets are sent. After voice/fax/modem is transmitted, data traffic is prioritized according to weight assign to each separate data queue (1 to 8) with levels from 1 to 16. Following is how the NetPerformer prioritizes traffic by default: • First Priority: Voice/Fax/Modem • Second Priority: SNA • Third Priority: IP

Silence Detection and Digital Speech Interpolation Voice communication by nature is half-duplex with pauses between sentences. Advanced voice processing algorithms take advantage of these two characteristics in silence processing, which significantly improves system performance in Frame Relay networks. The extra bandwidth saved from the silent period of one voice channel is allocated to other channels. This technique is called Digital Speech Interpolation and can improve bandwidth utilization by as much as 40%. Silence detection is configurable on NetPerformer. Network Jitter Network jitter is defined as the variance in delay from one voice packet to the next. Several elements may contribute to jitter variances and delays, including switch latency within the network, queuing at the network entry and exit points, and voice digitization and compression. Following is the typical delay of a voice call using ACELP-CN 8k single buffering.

Delay Input Buffer 18 ms 1

Compression 14 ms 1

Access Queue 1 to 20 ms Network Latency 25 to 250 ms 2

Far End Queue 1 to 5 ms Jitter Buffer 5 to 255 ms Decoder 4 ms 1

Traffic Flow Traffic flow is very important in sizing equipment, links, and trunks. For most networks, all legacy data travels in a single-star topology to the central site, while LAN traffic may be domain-oriented, and voice may be any-to-any. This means some links/trunks will handle more or less or equal parts of data and voice, so they must be sized appropriately. The proper number of channels must also be assigned per site depending on traffic flow, and this helps size the equipment required at the site. Ideally, your customer can also tell you what percentage of what traffic flows from one site to another In most data networks the flow of traffic is unidirectional; that is, it most frequently flows and uses network resources in a half-duplex fashion like file transfers do. Voice traffic, however, has less of a clear flow direction: Anyone from anywhere may need to talk to anyone else on the network. The impact of voice traffic flow is limited to the bandwidth utilization easily calculated for a given number of active voice channels. However, the impact of data traffic flow needs to be looked at a little more closely. Mixing Voice and Data Traffic: This section provides you with examples of how to calculate your voice and data application throughput requirements. The steps to follow are: First, mixing voice and data traffic, voice throughput is calculated separately from the data throughput (see CPS consumption for corresponding voice compression algorithms). Second, the real data throughput is obtained from subtracting the voice throughput. Finally the total bandwidth utilization is calculated by adding the voice bandwidth utilization (see table 1-3 for each voice compression algorithm corresponding bandwidth utilization value) and the data bandwidth utilization. Because throughput testing was conducted in the presence of continuous data flow, the CPS values showing in the above tables represent product performance under extreme conditions. In real-life applications, these conditions would be met at peak transfer times. If this is the case, and the CPS requirements should be exceeded, then the NetPerformer will automatically activate its flow control feature and apply traffic prioritization, thus delivering critical traffic as expected by the users.
