These prerequisites are discussed in detail in the Planning and Installation parts of the IAM.

Exceptions and Limitations—Selected Cases

This section highlights certain exceptions and limitations regarding features, deployment, and operation of this solution. It is not intended to be an exhaustive list. For access to all open and resolved caveats for the Cisco BLISS for Cable solution, see the "Caveats and Bug Toolkit" section.

Need to Reload the Configuration File Every Time After Restarting NRS

If you stop and start the NRS, routing policies are not loaded. The NRS issues the following error message: 404 routing policy has no algorithm. You must clear the persistent and reload the configuration file after each restart.

See caveat number CSCse49813. It is specific to Release 4.0.3.16 of the NRS.

Note The complete documentation for the Cisco NRS is available at http://www.cisco.com/univercd/cc/td/doc/product/voice/cscp/30/dsnrs30.pdf. This documentation is password protected. To obtain access, see the "Access to Password-Protected Documentation on Cisco Websites" section.

Module-Trigger Configurations Lost after NRS Restart

After you upgrade to NRS version 4.0.3.x (up to version 4.0.3.16), and restart the NRS, the module-trigger configurations are lost. Without the module-trigger commands, the stand-alone NRS cannot route calls properly. In this situation, after restarting the NRS, you must reconfigure the module-trigger configurations.

See caveat number CSCse53306. It is specific to Release 4.0.3.16 of the NRS.

Features Delivered on SIP Ingress Requiring Calling Party Identity

For all calls incoming to the Cisco BTS 10200 Softswitch over a SIP trunk group (TG), features that require the calling party identification (such as automatic recall, automatic callback, customer originated trace, and so forth), are supported only if one of the following is true:

•The USE-PAI-HDR-FOR-ANI token is set to N in the applicable incoming softswitch TG table of the Cisco BTS 10200 Softswitch.

or

•The USE-PAI-HDR-FOR-ANI token is set to Y in the applicable incoming softswitch TG table of the Cisco BTS 10200 Softswitch and the incoming SIP INVITE contains the P-Asserted ID (PAID) header.

See caveat number CSCsd07780.

CNAB for Outbound Calls on SIP Trunks

The Calling Name Blocking (CNAB) feature does not work for calls going out to SIP trunks. This is due to a SIP protocol limitation.

See caveat number CSCsa81305.

ENUM Server Availability Required if NRS Uses ENUM Routing Policy

By design, if ENUM routing policy is used on the NRS and all ENUM servers became unavailable, the NRS does not policy advance and those calls will fail. Therefore, if you have other routing policies configured on the NRS in addition to ENUM, and you want the system to invoke those policies in case the ENUM server lookup returns a name not found, you must ensure that at least one of the ENUM servers is always available.

See caveat number CSCsc63063.

Use of 302 Redirection and 503 Reject Messages in the NRS

The NRS allows the configuration of 302 redirection upon either a shutting-down or overload condition. However, the contact: header in the 302 redirect response does not contain any user-part information, therefore the Cisco BTS 10200 Softswitch is not able to redirect the call to another NRS. Because of this limitation, we recommend that you not configure the NRS to send a 302 message for shutting-down or overload condition when the NRS is interworking with the Cisco BTS 10200 Softswitch. Instead, we recommend that you use the 503 reject message. In this case the NRS rejects the call with the 503 response, and the Cisco BTS 10200 Softswitch uses an existing mechanism to retry another NRS node when it receives the 503 response.

See caveat number CSCsd90244.

Occasional Slow Response on NRS when Operating at Greater Than 65cps/tps with Large SIP Messages

A slow-response or congestion condition can occur on the NRS under the following conditions:

•The NRS is processing incoming requests continuously at the rate of more than 65 calls per second (or 65 transactions per second if NRS does not record-route).

•The SIP messages are large (more than 1000 bytes).

•The system is set at the default jvm maximum heap memory of 512 MB.

Under the conditions listed above, occasionally the NRS will take more than 500 ms to respond to incoming INVITE requests with "100 Trying." This can cause the originating SIP client to time out and retransmit the INVITE request. The condition can cause intervals of several seconds (up to 5 seconds) between consecutive INVITE requests; following that, the NRS might normalize and resume normal operation, that is, the NRS responds to the incoming INVITE with "100 Trying" within the 500 ms retransmission window.

As a workaround, for NRS deployments in networks with high call rates and large SIP messages size, we recommend that, after consulting with your Cisco technical representative, you consider setting the maximum jvm heap memory for the NRS to at least 1280 MB. The maximum jvm heap memory for the NRS is set from the <install-path>/bin/dsnrs_env.sh script.

Caution Consult with your Cisco technical representative before making any changes to <install-path>/bin/dsnrs_env.sh script.

For redundancy, always deploy the NRS in a cluster of more than two, and configure the SIP client peer to load-balance the INVITE requests between members in the NRS cluster. In addition, if possible, configure the SIP client peer to retransmit a timed-out INVITE to different member in the NRS cluster. This helps to avoid long post-dial delay.

For the configuration procedure, see "Adjusting the Memory Allocation" in the Installation chapter of the Name Resolution Server Administrator's Guide.

See caveat number CSCse28891.

CALEA Functionality

The following are the known limitations to providing CALEA compliance in Cisco BLISS for Cable Release 2.2.1. These are deemed to fall under the 18-month "safe harbor" exemption issued by the FCC in August, 2005. This functionality will be provided in Release 5.0 of the Cisco BTS 10200 Softswitch.

•No call content is tapped on calls forwarded outside of the CMS to which the targeted subscriber is locally attached. This is true if the call is forwarded to the PSTN or to another NCS endpoint on another CMS, for example:

User-C/User-P/User-X -> MGC/CMS2 -> NRS -> CMS1 -> UserA(forwarded) -> NRS -> MGC/CMS2 -> User-Q/User-Y

•No call content is tapped on NCS or PSTN calls forwarded to voicemail when the PSTN ingress MGC or calling party CMS, and the called party's CMS and VM SIP trunk, are not all the same Cisco BTS 10200 Softswitch. For example:

User-C/User-P/User-X -> MGC/CMS2 -> NRS -> CMS1 -> User A(CFNA to VM) -> VM

In this situation, CALEA compliance is provided only when the CMS and MGC are not separated. Perform the tap at the MGW in the PSTN case, and on the calling party CMTS in the NCS case. For example:

User-C/User-P -> MGC/CMS1 -> NRS (only for User-P's call) -> CMS1 -> User A(CFNA to VM) -> VM

•The treatment of call data depends on the status of targeted subscriber:

–For calls placed to/from a targeted NCS subscriber locally attached to that CMS, call data is sent by the CMS to the CALEA DF (Distribution Function).

–For calls terminated via, or ingressed from, an MGC on a different Cisco BTS 10200 Softswitch than the CMS to which the targeted subscriber is locally attached, call data is not sent, because the MGC was not instructed (via LAES headers sent from the targeted subscriber CMS) to send such call data to the DF.

For additional details about specific CALEA functions, limitations, and configuration in the BLISS for Cable 2.2.1 solution, contact your Cisco account team.

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
