New Hardware Features in Cisco IOS Release 12.2(2) XA

There are no new hardware and software features in the Cisco AS5400 for Cisco IOS Release 12.2(2) XA.

New Software Features in Cisco IOS Release 12.2(2) XA

The following new software features are supported in the Cisco AS5400 for Cisco IOS Release 12.2(2) XA.

Call Admission Control for H.323 VoIP Gateways

Before the call admission control feature, gateways did not have a mechanism to gracefully prevent calls from entering when certain resources were not available to process the call. This causes the new call to fail with unreported behavior, and could potentially cause the calls that are in progress to have quality related problems.

This feature set provides the ability to support resource-based call admission control processes. These resources include system resources such as CPU, memory, and call volume, and interface resources such as call volume.

If system resources are not available to admit the call, two kinds of actions are provided: system denial (which busyouts all of T1 or E1) or per call denial (which disconnects, hairpins, or plays a message or tone). If the interface-based resource is not available to admit the call, the call is dropped from the session protocol (such as H.323).

User Selected Threshold

This feature allows a user to configure call admission thresholds for local resources as well as memory and CPU resources. The list of local resources that are configured for call admission are described in the command description of "call threshold poll-interval".

With the call admission command, a user is allowed to configure two thresholds, high and low, for each resource. Call treatment is triggered when the current value of a resource goes beyond the configured high. The call treatment remains in effect until current resource value falls below the configured low. Having high and low thresholds prevents call admission flapping and provides hysteresis in call admission decision making.

With the call spike command, a user is allowed to configure the limit for incoming calls during a specified time period. A call spike is the term for when a large number of incoming calls arrive from the PSTN in a very short period of time (for example:100 incoming calls in 10 milliseconds).

Configurable Call Treatment

With the call treatment command, users are allowed to select how the call should be treated when local resources are not available to handle the call. For example, when the current resource value for any one of the configured triggers for call admission has reached beyond the configured threshold, the call treatment choices are as follows:

•TDM hairpinning — Hairpins the calls through the POTS dial peer.

•Reject — Disconnects the call.

•Play message or tone — Plays a configured message or tone to the user.

Resource Unavailable Signaling

This feature set supports the autobusyout feature where channels are busied out when local resources are not available to handle the call.

Autobusyout is supported on both channel associated signaling (CAS) and Primary Rate Interface (PRI) channels.

•CAS — Uses busyout to signal "local resources are unavailable."

•PRI — Uses either service messages or disconnect with correct cause-code to signal "resources are unavailable."

PSTN Fallback

The goal of PSTN fallback is to monitor congestion in the IP network and either redirect calls to the PSTN or reject calls based on the network congestion. Calls can be re-routed to an alternate IP destination or to the PSTN if the IP network is found unsuitable for voice traffic at that time. The user defines the congestion thresholds based on the configured network. This functionality enables the service provider to give a reasonable guarantee about the quality of the conversation to their VoIP users at the time of call admission.

---

Note PSTN fallback does not provide assurances that a VoIP call that proceeds over the IP network is protected from the effects of congestion. This is the function of the other Quality of Service (QoS) mechanisms such as IP Real-Time Transport Protocol (RTP) priority or low latency queuing (LLQ).

---

PSTN fallback includes the following features:

•Offers flexibility to define the congestion thresholds based on the network.

–Defines a threshold based on Calculated Planning Impairment Factor (ICPIF), which is derived as part of International Telecommunication Union (ITU) G.113.

–Defines a threshold based solely on packet delay and loss measurements.

•Uses Response Time Reporter (RTR) probes to provide packet delay, jitter, and loss information for the relevant IP addresses. Based on the packet loss, delay, and jitter encountered by these probes, an ICPIF or delay and loss values are calculated.

•Is supported by calls of any codec. Only G.729 and G.711 have accurately simulated probes. Calls of all other codecs are emulated by a G.711 probe.

For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122x/122xa/122xa_2/ft_pfavb.htm.

H.323 Scalability and Interoperability Enhancements

The Cisco H.323 Scalability and Interoperability Enhancements feature upgrades the Cisco H.323 Gatekeeper (GK) and Cisco H.323 Gateway to comply with H.323 Version 3. The enhancements in this release include:

•Support for mandatory H.323 Version 3 elements in the gateway and GK, including:

–multipleCalls

–maintainConnection

–alternateTransportAddresses

–useSpecifiedTransport

•Support for H.225 call signalling over UDP.

•Address resolution using border elements (BE).

•Support for bandwidth request (BRQ) messages.

•Support for concurrent calls over a single H.225 call signalling channel.

For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122x/122xa/122xa_2/ft323sca.htm.

V.92 Modem on Hold for Cisco AS5350 and Cisco AS5400 Universal Gateways and Cisco AS5800 Universal Access Servers

V.92 Modem on Hold allows a dial-in customer to suspend a modem session to answer an incoming voice call or to place an outgoing call while engaged in a modem session. When the dial-in customer uses Modem on Hold to suspend an active modem session to engage in an incoming voice call, the Internet service provider (ISP) modem listens to the original modem connection and waits for the dial-in customer's modem to resume the connection. When the voice call ends, the modem signals the telephone system to end the second call and return to the original modem connection, then the modem signals the ISP modem that it is ready to resume the modem call. Both modems renegotiate the connection, and the original exchange of data continues.

---

Note This feature is designed for use on telephone lines that are configured for call-waiting service; call-waiting signals trigger the suspension of the modem session. If call-waiting service is not present on the subscriber's line, other callers receive a busy signal, and the modem session is not interrupted.

---

For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122x/122xa/122xa_2/ftv92moh.htm.

V.92 Quick Connect for Cisco AS5350 and Cisco AS5400 Universal Gateways and Cisco AS5800 Universal Access Servers

V.92 Quick Connect speeds up the client-to-server startup negotiation, reducing the overall connect time up to 30 percent. The client modem retains line condition information and characteristics of the connection to the Internet service provider (ISP), which reduces connect time by avoiding some of the initial signal handshaking.

For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122x/122xa/122xa_2/ftv92qc.htm.

V.44 LZJH Compression for Cisco AS5350 and Cisco AS5400 Universal Gateways and Cisco AS5800 Universal Access Servers

V.44 LZJH is a new compression standard based on Lempel-Ziv that uses a new string-matching algorithm that increases upload and download speeds to make Internet access and Web browsing faster. The V.44 call success rate (CSR) is similar to V.42bis with significant compression improvement for most file types, including HTML files. V.44 applies more millions of instructions per second (MIPS) than V.42bis toward the same application data stream and yields better compression rates in almost any data stream in which V.42bis shows positive results.

V.44 supports automatic switching between compressed and transparent modes on NextPort DFC-108NP-bearing platforms. Automatic switching allows overall performance gain without loss in throughput for file streams that are not compressible.

V.44 is globally controlled through dialed number ID service (DNIS), calling line ID (CLID), and resource pool manager server (RPMS) virtual groups, and performance improvement is determined by the LZJH algorithms. The NextPort Dial Feature Card (DFC) is responsible for the ITU implementation of V.44 and the collection of statistics related to the new feature.

To support V.44 LZJH compression, the control switch module (CSM) has been modified. MIBs that show the status of V.42bis have been extended to show V.44 configuration status. New disconnect reasons help manage V.44 session status and debugging.

For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122x/122xa/122xa_2/ft_v44.htm.

Universal Port Resource Pooling for Voice and Data Services

Cisco Resource Pool Manager (RPM) enables telephone companies and Internet service providers (ISPs) to share resources for wholesale and retail network services in a single network access server (NAS) or across multiple NAS stacks. With Cisco RPM, service providers can count, control, and manage resources and provide accounting for shared resources when implementing different service-level agreements.

For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122x/122xa/122xa_2/ftuprp.htm.

Software Solutions in Cisco IOS Release 12.2(2) XA

The following solutions are supported in the Cisco AS5400 for Cisco IOS Release 12.2(2) XA:

Cisco Wholesale Voice Solution

The Cisco Wholesale Voice Solution provides service providers (SPs) with the required architecture design, network components, software features, functional areas, and provisioning methodologies needed to run a VoIP wholesale service. With an understanding of the concepts underlying the architecture, including interconnect topologies, components, and a variety of important issues that must be considered, the SP can then deploy options from a set of configuration templates. The result is a wholesale network that allows the SP to sell unbranded voice services to retailers, such as Internet telephony service providers (ITSPs), application service providers (ASPs), interexchange carriers (IXCs), or Post Telephone and Telegraph administrations (PTTs).

For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/sc/rel7/soln/wv_rel1/wsv_rn.htm.

Cisco SS7 Interconnect for Voice Gateways Solution 1.3

The Cisco SS7 Interconnect for Voice Gateways Solution is a distributed system that provides SS7 connectivity for Voice-over-IP (VoIP) access gateways by using the Cisco Signaling Controller (also referred to as the Cisco SC2200 product) and the access gateways as a bridge from the H.323 IP network to the PSTN network. This solution interacts over the IP network with other Cisco H.323 VoIP access gateways. In addition, the Cisco SS7 Interconnect for Voice Gateways Solution can interoperate with H.323 endpoints, using non-SS7 signaling such as ISDN PRI and channelized T1.

Software Features Ported from Other Platforms in Cisco IOS Release 12.2(2) XA

The following features have been previously released on other Cisco access servers and high availability platforms. Therefore the individual platform name may not be referenced for the Universal Gateways. Other differences may exist for the various platforms that are documented. For example, the Universal Gateways use SPE software and do not use VCWare. Please note the following discrepancies when referencing the feature modules:

•The AS5400 does not support the Mica Modem Card, Metrocom Modem Card, or VoIP Feature Card. Voice and modem functions are provided by the Universal Port Dial Feature Card running SPE firmware. See the Cisco AS5400 Card Installation Guide for more information.

•All references to the AS5300 in these documents apply to the AS5400 platform with the following exceptions:

–Use the AS54-DFC-108NP card instead of the Mica or Microcom modem cards.

–Use the dial feature card (DFC) instead of voice feature cards (VFC).

–Use SPE firmware instead of portware or vcware.

–Run Cisco IOS Release software, for VoIP functionality, that is compatible with the recommended Cisco IOS version software in your platform software configuration guide.

Session Initiation Protocol (SIP) Gateway

The SIP Gateway consists of the SIP feature, which is an alternative to H.323 Enhancements to the SIP for VoIP on Cisco Access Platforms feature, which adds call transfer and call hold capabilities and more headers to the SIP feature

For details, please see the following chapters in Configuring Voice Video, and Fax of the Cisco IOS 12.2 Documentation Set:

Caveats for Cisco IOS Release 12.2 XA

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only select severity 3 caveats are included in the caveats document.

This section contains only open and resolved caveats for the current Cisco IOS maintenance release.

All caveats in Cisco IOS Release 12.1 and Cisco IOS Release 12.1T are also in Cisco IOS Release 12.2(2) XA5.

---

Note The Cisco IOS Release 12.1 documentation set is used for these release notes because Cisco IOS Release 12.2(2) XA5 is based on Cisco IOS Release 12.1(5) T.
