Asynchronous Rotary Line Queuing
Description
Asynchronous Rotary Line Queuing solves problems that most telcos face when users vie for the same voice switch craft port resources within the telcos management network TMN's Data Communication Network (DCN). Voice switches such as the DMS have asynchronous management interface ports that need to be accessed by multiple engineers from various data centers in the network. Typically, there are three to four async ports but seven to eight users may contend for them at the same time.
Until now, telcos typically used a device from Infotron, a small niche player in the United Kingdom. This device allows rotary access to these ports. Users who tried to access these ports after initial ports were busy were put into a queue to wait for a free port. In other words, they couldn't get cleared because of busy ports; they were suspended and had to wait in queue. Asynchronous Rotary Line Queuing solves this issue for central offices.

ISDN Network Side for ETSI Net5 PRI
Description
The ISDN Network-Side PRI for ETSI NET5 feature enables Cisco IOS Software to replicate the public switched network interface to a PBX that is compatible with ETSI NET5.
Routers and PBXs are both traditionally CPE with respect to the public switched network interfaces. For voice over IP (VoIP) applications, it is desirable to interface routers to PBX's with the router representing the public switched network.
Enterprise organizations use the VoIP feature with Cisco products as a method to reduce long-distance costs for phone calls within and outside of their organizations. However, sometimes a call cannot be placed over VoIP, and the call needs to be placed using the PSTN. The customer then needs two devices connected to a PBX to allow some calls to be placed using VoIP and some calls to be placed over the PSTN.
The ISDN Network-Side PRI will allow Cisco ISDN-enabled routers to switch calls across interfaces as legacy phone switches do today and mimic the behavior of the legacy phone switches. As shown in Figure 3, when a call arrives at the router, it is either passed to VoIP or terminated on the router.

Cable Interface Bundling
Description
Interface bundling aids in the distribution of IP addressing across RF line cards in a single UBR7200 chassis without adding the disadvantages of a bridged CMTS. Current software consumes an IP subnet for each RF line card, while lessening IP subnet consumption is considered critical for several customers. A solution to reduce the number of subnets consumed per UBR7200 is therefore required. Cable interface bundling allows a service provider to share one IP subnet across multiple cable interfaces that are grouped into a cable interface bundle. This eliminates the need to designate a separate IP subnet for each individual cable interface. This in turn avoids the performance, memory, and security problems that would result if a bridging solution were used to manage the subnets, especially for a large number of subscribers.
Interface bundling allows the conservation of IP subnets, while retaining its routing functionality between cable interfaces and to the egress port. Routed networks provide:

Point-to-Point Wireless Support for the Cisco uBR7200 Series
Description
Point-to-point wireless is defined as a fixed dedicated wireless link from one site to another.
Broadband wireless is a system that delivers tens of megabits of data, using microwave or millimeter-wave radio technology.
This product delivers 44-Mbps full-duplex point-to-point (PTP) fixed-site data in a 12-MHz RF channel in the MMDS band (2.500 to 2.690 GHz) and the U-NII band (5.725 to 5.825 GHz). Future phases will deliver lower data rates in other frequency bands.
The PTP wireless router is be an integrated solution, which will consist of a base router (Cisco universal broadband router 7246), a wireless modem line card, an RF head unit, a power-feed panel, cables, and antenna subsystems. This PTP wireless router will be deployed in a service provider's "network cloud" environment, as well as in enterprise campus locations. Thus, the target customers for the PTP wireless router will be both the service provider channel and the enterprise end user.
The PTP wireless router system will be positioned as another option in the broadband access portfolio of Cisco solutions. Currently, these solutions consist of Digital Subscriber Lines (DSL) and cable technologies.
The PTP link is a "last-mile-access" link to reach local customers. It is not targeted for a "long-haul" or "backbone" application. The distinction is in the performance requirements normally assigned to a "last-mile" link in a telecommunications network. Of course this does not prevent it from being used in a "backbone" or "backhaul" application when the performance meets specified needs.

FR/ATM Service Interworking (FRF.8)
Description
Frame Relay (FR)/ATM service interworking (IW) is a technique to allow communication between a Frame Relay end user and an ATM end user. The technique is based upon the FRF.8 (Frame Relay Forum) Implementation Agreement (IA). FRF.8 specifies that a Frame Relay end station may communicate with an ATM end station provided that there is a router that is performing FRF.8 in software between the two end stations. FRF.8 essentially allows protocol translation of Frame Relay traffic to ATM traffic. It is for permanent virtual circuit (PVC)-based networks only and requires a one-to-one mapping of FR PVCs to ATM PVCs.

FR/ATM IW is a technique to allow transport of Frame Relay traffic through an ATM network. The technique is based upon the FRF.5 implementation agreement specifies that two Frame Relay end stations may communicate with each other through an ATM network between the end stations. This works provided that there are routers at each side of the end stations that are performing FRF.5 in software between the FR and ATM ports. FRF.5 essentially allows tunneling of Frame Relay traffic through an ATM network. It is for based networks only and allows multiple FR PVCs to be multiplexed onto a single ATM PVC.

AAA Server Group Deadtimer
Description
In previous Cisco IOS Software releases, a limited configuration may be applied to a AAA server group that includes the list of AAA servers in the server group. The AAA Server Group feature allows users to select a subset of servers from a global host list and use the server group for a particular service. The currently supported server host types are RADIUS and TACACS+ server hosts.
A global configuration sets the deadtime in minutes when to stop waiting for a non-responding server.
With the AAA Server Group Deadtimer feature the deadtime configuration will be configured per server group. The deadtime attribute is supported only for RADIUS hosts. If the deadtime is defined globally, the local server group deadtime configuration will override the global configuration.

Network Side PRI Signaling, Trunking, and Switching
Description
The Network side PRI Signaling, Trunking, and Switching feature enables Cisco IOS Software to replicate the public switched network interface to a PBX. Network Side PRI enables the NAS to provide a standard ISDN PRI network-side interface to the PBXs and mimic the behavior of legacy phone switches. To a PBX, the NAS functions as a National ISDN PRI switch type or an ETSI PRI Net5 switch. No change in PBX capability or behavior is required.
Call switching using dial peers enables Cisco (voice-over-IP) VoIP gateways to switch voice and data calls between different interfaces based on the dial peer matching. An incoming call is matched against configured dial peers, and based on the configured called number, the outgoing interface is selected. Any call that arrives from an ISDN PRI network side on a supported platform is either terminated on the NAS, switched to an IP network, or switched to the PSTN, depending on the configuration. A dial peer is an addressable call endpoint identified, for example, by a phone number or a port number. In VoIP, there are two kinds of dial peers: POTS and VoIP. The Cisco AS5800 access server switches both voice and data calls. The Cisco AS5300 access server switches only voice calls.
The Trunk Group Resource Manager (TGRM) supports the logical grouping, configuration, and joint management of one or more PRI interfaces. The TGRM is used to store configuration information and to accept or select an interface from a trunk group when requested. A trunk group is provisioned as the target of a dial peer, and the TGRM transparently selects the specific PRI interface and channels to use for incoming or outgoing calls. A trunk group can include any number of PRI interfaces, but all the interfaces in a trunk group must use the same type of signaling.
The Class of Restrictions (COR) functionality provides the ability to deny certain call attempts based on the incoming and outgoing class of restrictions provisioned on the dial peers. This functionality provides flexibility in network design, allows users to block calls (for example, to 900 numbers), and applies different restrictions to call attempts from different originators. COR is used to specify which incoming dial peer can use which outgoing dial peer to make a call.
In Cisco IOS Software Release 12.1(2)XH, the trunking and COR parts of this feature are available only on the Cisco AS5800. The remainder of the feature is platform independent.

Description
NTT PRI NFAS adds the NTT switch type to the existing ISDN PRI NFAS with D Channel Backup feature.
ISDN Non-Facility Associated Signaling (NFAS) allows multiple ISDN Primary Rate Interfaces (PRIs) to be controlled by a single D channel. The NTT switch type for NFAS does not use an associated D channel for backup.
Once the channelized T1 controllers are configured for ISDN PRI, only the NFAS primary D channel must be configured; its configuration is distributed to all the members of the associated NFAS group.

PPP over ATM SVC's
Description
As DSL deployments scale to beyond the trial stage of <1000 customers to upwards of millions of customers, efficiencies must be brought about in the provisioning of the service. Currently, DSL service has been standardized on PPP over ATM. In provisioning a customer, PVC's are "nailed up" between the subscriber and the Network Access Provider (NAP) or, in some cases, all the way to the Network Service Provider (NSP). The cost of provisioning these subscribers with PVC's, even as GUI based provisioning alternatives are developed, are untenable from the service provider's (esp. NAP) viewpoint. Enabling service providers with PPP over ATM SVC's will reduce this cost as well as enhance the manageability of DSL services.
Support for PPP over ATM SVC's will also help NAP's provide services to end-users by providing a method of destination selection as well as QoS selection. Based upon the invoked address, a VC will be set up that sets up a PPP session for a particular level of bandwidth and service (VBR, UBR etc.) as well as to the particular network of interest (e.g. ISP1, ISP2, Corp1, Corp2). With telecommuting and home networking becoming more prolific, support for multiple destinations will become a standard requirement.
From an end-to-end perspective, the Cisco DSL product line is able to leverage PPP over ATM SVC's from either the NAP or the NSP perspective. While, the CPE and DSLAM will have very little to offer, the aggregation device in the NAP and the termination and service delivery device in the NSP (either the Cisco 6400 or 7200 series in both cases) will need to have SVC functionality. On the client side, Microsoft is building SVC capability into Windows 98 an extending it in Win2000 (includes ILMI support). With this feature, Cisco leads the market in enabling end-to-end SVC's. At the SVC termination point, layer 2 service selection of this type can then lead to layer 3 selection at the NSP (provided for by Vulcan/SSG functionality in the Cisco 6400).

TCP Clear Performance Optimization
Description
The feature provides inbound and outbound performance optimization for service providers who provide ports to America Online (AOL) using the Cisco AS5800. This feature enables an AS5800 to support 1344 (2 x T3) clear-channel Telnet sessions, otherwise known as "TCP-Clear". Each TCP-Clear session carries data for a single AOL user.
Outbound TCP-Clear traffic handling is now event-driven and processed at interrupt level. In addition, the flow control algorithm is enhanced to handle the higher volume of traffic and to eliminate some out-of-resource conditions that could result in abnormal termination of the session.
Inbound TCP-Clear traffic has the same optimizations as outbound, and scanning for special characters is also eliminated. This scanning is required on a normal Telnet session to process Telnet control sequences but is CPU intensive. In TCP-Clear, no Telnet control sequences are ever sent. In addition, a Nagle algorithm is used to form the inbound data stream into larger packets, minimizing packet-processing overhead.

General Packet Radio Service (GPRS)
Description
General Packet Radio Service (GPRS) is defined and standardized by the European standards body ETSI. GPRS is a packet-based (IP/X.25) data service for GSM networks. The GPRS network essentially consists of two major elements, the serving GPRS support node (SGSN) and gateway GPRS support node (GGSN).
Cisco GGSN is the gateway to IP-based network and services, whether it is the public Internet or a corporate intranet. The GGSN provides authenticated access for a mobile subscriber for resources in the IP domain, whether it is to connect to a corporate network or an ISP, for data services such as e-mail, Web browsing, or other Internet-based applications. Cisco GGSN is a software solution on standard Cisco IOS router platform. Thus, the Cisco GGSN leverages all the benefits of Cisco IOS technology such as support for routing protocols and features such as DHCP, NAT, VPN, IPSec., and so on.

Distributed FRF.11/.12
Description
FRF.11 provides a standards-base voice transport, and FRF.12 provides a standards-based data fragmentation mechanism over Frame Relay. When voice and data frames are interleaved in a Frame Relay network using low-speed links or low CIR values, fragmentation of large data frames becomes necessary to avoid excessive delays experienced by real-time traffic such as voice.
Distributed FRF.11/12 provides the above functionality for the VIP on the Cisco 7500 series router. This feature moves the voice encapsulation and the data fragmentation function into the distributed CEF path in the VIPs, increasing the overall performance and scalability of the system. This occurs by offloading the central processor from the memory and computing intensive tasks such as fragmentation and reassembly of data frames, as well as voice encapsulation. Another important advantage of confining the handling of voice and data packets to the VIP is the reduced latency by shortening the processing path inside the system
With Distributed FRF11/12 feature, the Cisco 7500 series router becomes a strong play in the multiservice and voice aggregation solution space.
