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)YL.
New Software Features in Release 12.2(8)YL
Cisco IOS Release 12.2(8)YL on the Cisco ICS 7750 supports the new software features described in this section.
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.
Table 7 Interface Card Support for Cisco ICS 7750 Analog and Digital Voice-Only Systems
Interface Card Supported on ICS-7750-AV Supported on ICS-7750-DV
1 To run WAN interface cards on a voice-only system, a Data Networking system upgrade is required. A Data Networking system upgrade is not required for routing data over a LAN.
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.
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 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)YL. 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 toCisco.com and click Service & Support: Technical Assistance Center: Tool Index: 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)YL
This section describes unexpected behavior in Release 12.2(8)YL.
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.
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.
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).
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 0/0shutdownno ds0-group 0 timeslots 1-24no tdm clock T1 0/0controller T1 0/1shutdownno ds0-group 1 timeslots 1-24no tdm clock T1 0/1tdm clock T1 0/0 voice export linetdm clock T1 0/1 voice import T1 0/0 internalcontroller T1 0/0ds0-group 0 timeslots 1-24 type e&m-wink-startno shutdowncontroller T1 0/1ds0-group 1 timeslots 1-24 type e&m-wink-startno 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 0/0no ds0-group 0 timeslots 1-24no tdm clock T1 0/0controller T1 0/1no ds0-group 1 timeslots 1-24no tdm clock T1 0/1tdm clock T1 0/0 voice export linetdm clock T1 0/1 voice import T1 0/0 internalcontroller T1 0/0ds0-group 0 timeslots 1-24 type e&m-wink-startcontroller T1 0/1ds0-group 1 timeslots 1-24 type e&m-wink-start
