1 In addition to the Cisco IOS software listed above, each software bundle contains the following software: Cisco IOS software for the system switch processor (SSP) card, ICS System Manager, ICS Core Software, and system alarm processor (SAP) software. The x.x.x in the system software bundle name represents the release number. For example, for release 2.4.0, the name of the bundle containing the IP/Voice Plus image would be S77a-2.4.0.

2 Flash memory is not used for the Cisco IOS image on ASIs and MRP200s. Since onboard flash is not available on ASIs and MRP200s, a Cisco IOS compressed image resides on the system processing engine (SPE) and is downloaded to the RAM of each ASI or MRP200 before image decompression.

3 You can upgrade ASI or MRP card memory to 80 MB, 96 MB, or 128MB by installing a dual in-line memory module (DIMM) in the card DIMM slot. For memory upgrade instructions, refer to Installing Memory, PVDM, and VPN Modules in ASI Cards, MRP Cards, and SPE Cards in the Cisco ICS 7750.

4 This image comprises one of the new voice-only packages, and does not include data networking support. For more information, see the "New Software Features in Release 12.2(8)YM" section.

MRP and ASI Card Upgrades

You can upgrade MRP and ASI cards as follows:

Memory. MRP and ASI cards ship with 64 MB of dynamic RAM (DRAM). You can upgrade MRP and ASI card memory to 80 MB, 96, or 128 MB by installing a dual in-line memory module (DIMM) in the card DIMM slot.

Voice and data processing power. VICs, VWICs, and FXS modules installed in MRP or ASI cards might require additional digital signal processors (DSPs) for processing heavier volumes of voice traffic. You can install Packet Voice/Data Modules (PVDMs) in one or both of the card PVDM slots to give MRP and ASI cards more processing power.


Note See Installing Memory, PVDM, and VPN Modules in ASI Cards, MRP Cards, and SPE Cards in the Cisco ICS 7750 for instructions on how to upgrade ASI and MRP cards.

New and Changed Information

The following section lists the new software features supported by the Cisco ICS 7750 for Cisco IOS software Release 12.2(8)YM.

New Hardware Features in Release 12.2(8)YM

Cisco IOS Release 12.2(8)YM on the Cisco ICS 7750 supports the four-port FXO VIC, as described below.

Four-Port Foreign Exchange Office for the United States with Battery Reversal (VIC-4FXO-M1)

The Cisco ICS 7750 now supports an FXO-M1 VIC with four ports, which you can use to connect to PBXs or key systems and to provide off-premise connections in the U.S., Canada and other countries. FXO-M1 is an enhancement of FXO with battery reversal and Caller ID features.


Note You can use H.323 with the Caller ID and battery reversal answer supervision features on the VIC-4FXO-M1. Media Gateway Control Protocol (MGCP) on the VIC-4FXO-M1 is supported, but not with Caller ID or battery reversal detection.


New Software Features in Release 12.2(8)YM

Cisco IOS Release 12.2(8)YM on the Cisco ICS 7750 supports the following software features:

VLAN Support

QoS Support

Gateway Resource Availability Reporting

Cisco ICS 7750 Voice-only Systems

VLAN Support

The availability of the MRP300, MRP3-8FXS, and MRP3-16FXS cards enables most of the IOS software virtual LAN (VLAN) features on the Cisco ICS 7750.

Understanding VLANs

A VLAN is a switched network that is logically segmented on an organizational basis, by functions, project teams, or applications rather than on a physical or geographical basis. For example, all workstations and servers used by a particular workgroup team can be connected to the same VLAN, regardless of their physical connections to the network or the fact that they might be intermingled with other teams. Reconfiguration of the network can be done through software rather than by physically unplugging and moving devices or wires.

A VLAN can be thought of as a broadcast domain that exists within a defined set of switches. A VLAN consists of a number of end systems, either hosts or network equipment (such as bridges and routers), connected by a single bridging domain. The bridging domain is supported on various pieces of network equipment; for example, LAN switches that operate bridging protocols between them with a separate bridge group for each VLAN.

VLANs are created to provide the segmentation services traditionally provided by routers in LAN configurations. VLANs address scalability, security, and network management. Routers in VLAN topologies provide broadcast filtering, security, address summarization, and traffic flow management. None of the switches within the defined group will bridge any frames, not even broadcast frames, between two VLANs.


Note For more information about VLANs, refer to the "Routing Between VLANs Overview" chapter in the Cisco IOS Switching Services Configuration Guide.


Cisco ICS 7750 VLAN Guidelines

When configuring multiple VLANs on the Cisco ICS 7750, follow the guidelines below:

All system cards in the chassis must be a member of the management VLAN (VLAN 1).

At least one flash-based MRP must be configured to be on all VLANs. This is necessary to route data between VLANs.

Outside the chassis, the SSP can support a maximum of 250 VLANs and 64 STP instances. The maximum number of VLANs the MRP300 can support is 300.

The management VLAN (VLAN 1) IP address of the MRP300 must be configured via ICSConfig, and therefore must reside on the primary fast Ethernet interface (0/0) of the MRP300.

Do not add a native VLAN sub-interface on the MRP300.

Do not configure the primary Fast Ethernet interface on the MRP300 to have "no ip address."

QoS Support

The availability of the MRP300, MRP3-8FXS, and MRP3-16FXS cards also enables the IOS software Quality of Service (QoS) features on the Cisco ICS 7750.

Configuring Quality of Service

Separating voice and data packets onto different VLANs will not, by itself, ensure voice quality. You need to have a well-engineered, end-to-end network for running delay-sensitive applications such as Voice over IP (VoIP). Voice traffic is much more sensitive to timing variations than data traffic. For good voice performance, you need to configure the data network so that voice packets are not lost or delayed. Fine-tuning the network to adequately support VoIP involves selecting a series of protocols and features to improve QoS. Cisco IOS software provides many tools for enabling QoS on the backbone, such as random early detection (RED), weighted random early detection (WRED), Fancy Queuing (that is, custom, priority, or weighted fair queuing), and IP precedence. To configure your IP network for real-time voice traffic, you must take into consideration the entire scope of your network and then select the appropriate QoS tool or tools.


Note QoS measures the level of network performance. It does not directly measure the quality of the voice signal.


The important thing to remember is that QoS must be configured throughout your network—not just on the MRP running VoIP—in order to improve voice network performance.


Note For additional information about configuring QoS, refer to the
Cisco IOS Quality of Service Solutions Configuration Guide.


Gateway Resource Availability Reporting

Cisco H.323 Version 2 support enables gatekeepers, gateways, and proxies to send and receive all the required fields in H.323 v2 messages. One of features in H.323 Version 2 is the Resource Availability Indicator (RAI).

Understanding RAI

RAI is a resource-based call admission control (CAC) mechanism which is sent from the terminating gateway to the gatekeeper to provide information about the gateway's ability to take more calls. Because it is a gateway/gatekeeper indication, RAI CAC applies only to H.323 voice networks that utilize a gatekeeper design.

The gateway reports its resource status to the gatekeeper using the RAI. When a monitored resource falls below a configurable threshold, the gateway sends an RAI to the gatekeeper indicating that the gateway is almost out of resources. When another configurable threshold is reached, the gateway sends an RAI indicating that the resource depletion condition no longer exists. Resources that are monitored are DS0 channels and digital DSP channels. Analog DSP channels, analog voice ports, BRI voice ports, and router CPU and memory are not monitored.

Resource reporting thresholds are configured by entering the resource threshold command. The upper and lower thresholds are separately configurable to prevent the gateway from operating sporadically due to the availability or lack of resources.

When you are calculating utilization, you should calculate based on available channels (disabled channels are not counted). Entering the command show call resource voice stats displays these details for both DSP and DS0 resources.

RAI Limitations on the Cisco ICS 7750

Unlike other platforms which support RAI, which allow a voice call to be made using any supported codec whenever one DSP channel is free, on the Cisco ICS 7750, even when there is one DSP channel available, only G.711 voice calls will be successful. Requests for higher complexity codecs in this scenario will fail.

Cisco ICS 7750 Voice-only Systems

The Cisco ICS 7750 Voice-only Systems are IP telephony product bundles that include the Cisco ICS 7750 hardware and software components for Cisco CallManager support (up to 50 IP phones), PSTN connectivity, analog business device connectivity and Cisco Unity Voice Mail (for 25 voice mail boxes). They are designed for customers with 50 or fewer IP phones who need standalone voice functionality and want the flexibility to add more advanced data routing and voice over the WAN networking functionality as their business needs change. There are currently two Cisco ICS 7750 Voice-only systems:

ICS-7750-AV—Includes Cisco CallManager and Cisco Unity support as described above, and support for analog VICs as shown in Table 7.

ICS-7750-DV—Includes Cisco CallManager and Cisco Unity support as described above, and support for both analog VICs and digital VWICs as shown in Table 7.

Upgrading the ICS 7750 Voice-only Systems With IOS Feature Licenses

This section describes the upgrade options available for voice-only systems.

Digital voice system upgrade—To upgrade your ICS 7750-AV System with a digital voice image, you must purchase a digital voice image feature license (Part No. SW-ICS-DV-UPGD=). This feature license entitles you to download the digital voice IOS image (ics7700-sv3y10-mz) from Cisco Connection Online (CCO) and load the image to your ICS 7750-AV System. This upgrade enables digital voice interface cards to function in an analog voice system. Load the digital voice image to the ICS 7750 Voice-only system and add the desired digital voice interface cards along with the appropriate Digital Signal Processor (DSP) modules.

A digital voice image upgrade entitles you to connect to the Public Switch Telephone Network (PSTN) using digital voice trunks. It does not entitle you to use that digital voice interface card for data channel groups. To add data channel group support to a digital voice interface card, you must purchase a data networking feature license.

Data networking system upgrade—Data networking image upgrades are authorized only for an ICS 7750-DV System or for an ICS 7750-AV System that has been already upgraded with a digital voice image feature license. To upgrade your ICS 7750 Voice-only System with data networking, you must purchase a data networking feature license (Part No. SW-ICS-DN-UPGD=). This feature license entitles you to download the data networking IOS image (ics7700-sv3y-mz) from CCO and load the image to your Cisco ICS 7750. With a data networking IOS image upgrade, you are entitled to route voice and data traffic over the WAN. You are also authorized to configure data channel groups on a Voice/WAN Interface Card (VWIC).

To enable the data networking image, load the image to the Cisco ICS 7750 and add the desired WAN interface cards (WICs). For a complete list of WICs, see the WICS denoted with a footnote in Table 7.

Security and legacy protocol image upgrades—In order to upgrade to an IOS image with data encryption (that is, IP SEC 56 or IP SEC 3DES) and/or legacy protocols (that is, IBM SNA or Apple Talk), you must first upgrade your ICS 7750 Voice-only System with data networking under the terms and conditions outlined in the Data Networking System Upgrade section. The data networking system upgrade contains the base IP/VOICE PLUS IOS image (ics7700-sv3y-mz).

For example, if you would like to route encrypted data traffic between two sites that have ICS-7750 voice-only systems, you must upgrade both systems with the data networking system upgrade. To add data encryption, purchase one of the IP SEC images listed in Table 1.

Upgrading directly to an IP SEC and/or legacy protocol IOS image from a voice-only IOS image is unauthorized without first purchasing a data networking system upgrade. In addition, a spare IP VOICE PLUS image may not be loaded to your voice-only system in place of purchasing the data networking system upgrade (Part No. SW-ICS-DN-UPGD=).

Upgrading the Cisco CallManager user license on ICS 7750 voice-only systems—The Cisco CallManager in the ICS 7750 Voice-only Systems contain full-featured CallManager support for up to 50 IP phones. The Cisco CallManager in the ICS 7750 Voice-only System should not be used with more than 50 IP Phones, unless a CallManager License upgrade has been purchased. You must purchase a Cisco CallManager License upgrade (Part No. SW-CCM-VO-UPGD=) if more than 50 IP phones are running on your ICS 7750 Voice-only System.

Important Notes

The following sections contain important notes about Cisco IOS-related issues that can apply to the Cisco ICS 7750.

Software Images on MRP and ASI Cards

All of the MRPs and ASIs in a Cisco ICS 7750 must run the same Cisco IOS image.

Caveats

Caveats describe unexpected behavior or defects in Cisco IOS software releases. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels.

Caveats in Release 12.2 T are also in Release 12.2(8)YM. For information on caveats in Cisco IOS Release 12.2 T, refer to the Caveats for Cisco IOS Release 12.2 T document. For information on caveats in Cisco IOS Release 12.2, refer to the Caveats for Cisco IOS Release 12.2 document. These documents list severity 1 and 2 caveats, and are located on CCO and the Documentation CD.


Note If you have an account with Cisco.com, you can also use the Bug Toolkit to find select caveats of any severity. To reach the Bug Toolkit, log in to Cisco.com and click Technical Support:
Tools & Utilities: Software Bug Toolkit. Another option is to go to http://www.cisco.com/cgi-bin/Support/Bugtool/launch_bugtool.pl


Open Caveats - Release 12.2(8)YM

This section describes unexpected behavior in Release 12.2(8)YM.

CSCdz23298

If FXO channel associated signaling (CAS) is used on an MRP300, the MRP300 might reload sporadically.

Workaround—Use E&M signaling instead of FXO signaling, or downgrade to Release 12.2(4)YH.

CSCdy06510

In rare cases, it is possible that when performing load testing, certain ports on the MRP3-16FXS might stay in an off-hook state after the testing is complete.

There is no workaround.

CSCdy18325

In rare cases, when a call is made through an FXO-M1 interface, the call is successful, but the Caller ID information might be lost, and the following error message might be generated:

%SYS-5-TABLEERR: VTSP table active calls damaged: node added twice?

There is no workaround.

CSCdy19867

When a call to the PSTN is being made through MRP FXS and FXO interfaces on which the forward-digits all command has been entered, it is possible that the DTMF tones might be echoed back to the call originator, due to a suspected problem with the echo canceller.

Workaround—Tuning the echo canceller settings and disabling the forward all digits functionality on the necessary FXS and FXO interfaces should help solve this problem. Refer to the following documentation for more information:

Cisco IOS Voice, Video, and Fax Configuration Guide

IP Telephony Solution Guide

Voice Parameters and Tuning Guide

CSCdy24276

If all of the interfaces are being used on an MRP3-16FXS, it possible that an error message similar to the following will be displayed for each interface:

2w1d: %IPM_C54X-1-TOOBIG: DSP 3, packet(size 65151) too big.

There is no workaround.

CSCdx88902

If 2 Mbps of data is sent over a 2 Mbps link when there are 24 voice calls already in process on an MRP or ASI, the CPU utilization on the MRP or ASI will increase and will cause some data packets to be dropped. For a brief period, some calls might be dropped during call setup, but the system will automatically recover. Calls in progress will not be affected.

One or more of the following syslog messages might be generated in response to this condition:

%IPM_C54X-1-TOOBIG: DSP 6, packet (size 16460) too big.
%IPM_C54X-3-HOST_XMIT_BLOCKED: Host is unable to transmit packets to DSP 6
%VTSP-3-DSP_TIMEOUT: DSP timeout on event 0x6: DSP ID=0x1: DSP Disc (call mode=0)
%IPM_C54X-3-NO_BUFFERS: No buffers available for DSP buffer pool
%IPM_C54X-1-DSP_TIMEOUT: dsp 1 NOT RESPONDING.

Workaround—Reduce the data traffic to the extent required to reduce or eliminate dropped data packets.

CSCdx81837

If you are configuring T1 PRI or E1 PRI on an ASI81 or MRP, the total number of channels shown when you enter the show run command might not correspond to the actual number of usable PRI channels.

Workaround—Always enter the show voice dsp command to determine how many DSPs are available before attempting to configure T1 PRI or E1 PRI on ASI81 or MRP.


Note If you encounter this problem, you can use either of the following approaches to solve it: enter the isdn service command to take individual channels out of service (refer to the documentation for the
isdn service command), or enter the isdn busy command to set a false busy signal on individual channels (refer to the documentation for the isdn busy command).


CSCdy02040

If you are using an MRP or ASI with an E1 or T1 CAS trunk, if you change the TDM clocking on an E1 or T1 controller from an export clock configuration to an import clock configuration, and if the E1 or T1 controller is shut down when its clocking is changed, then configuring a DS0 group and entering a no shut command on that controller will cause intermittent call failures on some time slots.

For example, if interface T1 0/0 is configured as an export clock and interface T1 0/1 is also configured as an export clock, the following sequence of commands will cause intermittent call failures on T1 0/1:

    controller T1 0/0
    shutdown
    no ds0-group 0 timeslots 1-24
    no tdm clock T1 0/0

    controller T1 0/1
    shutdown
    no ds0-group 1 timeslots 1-24
    no tdm clock T1 0/1

    tdm clock T1 0/0 voice export line
    tdm clock T1 0/1 voice import T1 0/0 internal

    controller T1 0/0
    ds0-group 0 timeslots 1-24 type e&m-wink-start
    no shutdown

    controller T1 0/1
    ds0-group 1 timeslots 1-24 type e&m-wink-start
    no shutdown 

Workaround—Do not shut down the E1 or T1 controller before changing its tdm clock configuration. Based on the example shown above, the following configuration will work:

    controller T1 0/0
    no ds0-group 0 timeslots 1-24
    no tdm clock T1 0/0

    controller T1 0/1
    no ds0-group 1 timeslots 1-24
    no tdm clock T1 0/1

    tdm clock T1 0/0 voice export line
    tdm clock T1 0/1 voice import T1 0/0 internal

    controller T1 0/0
    ds0-group 0 timeslots 1-24 type e&m-wink-start

    controller T1 0/1
    ds0-group 1 timeslots 1-24 type e&m-wink-start

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available through the Cisco TAC: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Inquiries to Cisco TAC are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to the following URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:

http://www.cisco.com/register/

If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com registered user, you can open a case online by using the TAC Case Open tool at the following URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled; for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). In addition, please have available your service agreement number and your product serial number.
