Release Notes for the Cisco SS7 Interconnect for Voice Gateways Solution, Version 2.1

These release notes describe the hardware and software requirements, features, and caveats for Release 2.1 of the Cisco SS7 Interconnect for Voice Gateways Solution. The following sections list the contents of this document and describe the solution and its components.

Introduction

The Cisco SS7 Interconnect for Voice Gateways Solution is a distributed IOS call control system that provides SS7 connectivity for Cisco AS5xxx Universal Gateways by using the Cisco PGW 2200 Softswitch.

Note The Cisco PGW 2200 Softswitch was formerly referred to as the Cisco PGW 2200 PSTN Gateway or the Cisco SC2200.

The Cisco SS7 Interconnect for Voice Gateways 2.1 solution performs the following functions:

•

Directly connects voice gateways to the public switched telephone network (PSTN) in a peer-to-peer interconnect

•

Supports Cisco H.323/SIP AS5xxx Universal Gateways, gatekeepers, and proxy servers

New Features

There are no new features in the Cisco SS7 Interconnect for Voice Gateways Solution for Release 2.1. You can find information on new features for the individual components that make up the solution in their associated release notes.

Solution Issues

Handover-Split Mode Limitations

Cisco AS5850s configured for handover-split mode operate under the following limitations:

•

Each Cisco AS5850 can support two CT3 trunks. Cisco AS5850s configured for classic-split mode can support up to four CT3 trunks each.

•

Because the Cisco PGW 2200 Softswitch can support only two RLM (Redundant Link Manager) links in an NFAS group, you can assign only one interface to each RSC (route switch controller) card in a Cisco AS5850 operating in handover-split mode. This prevents link redundancy between the individual RSCs and the Cisco PGW 2200s.

•

If an RSC fails, it takes up to 2 minutes for the active RSC to take over for the failed RSC. During this time, calls handled by the failed RSC are dropped, and new calls are not accepted. Calls handled by the active RSC are not affected by a switchover.

•

There is intermittently a 2- to 3-second outage (dsp timeout event errors and no bearer path) when redundancy handover peer-resources is executed. You might face this problem in the field if one of the RSCs fails temporarily. Run handover peer-resources after the failed RSC is back in service.

Use the redundancy handover peer-resources busyout-period command when instructing the active RSC to release control of the slots usually controlled by the standby RSC. This prevents dsp timeout event errors caused by the sudden disruption of active calls that are using the DSP resources on the relinquished slots.

Using BAMS with Cisco MNM

Cisco MNM does not collect or display BAMS measurements from a Cisco PGW 2200 Softswitch operating in Signaling mode. Measurements must be collected through use of a different method.

Caveats

Caveats describe unexpected behavior in the Cisco SS7 Interconnect for Voice Gateways Solution.

Obtaining Technical Assistance

For all customers, partners, resellers, and distributors who hold valid Cisco service contracts, Cisco Technical Support provides 24-hour-a-day, award-winning technical assistance. The Cisco Technical Support Website on Cisco.com features extensive online support resources. In addition, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not hold a valid Cisco service contract, contact your reseller.

Cisco Technical Support Website

The Cisco Technical Support Website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, 365 days a year, at this URL:

Access to all tools on the Cisco Technical Support Website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support Website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

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)—Your 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 operation 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 your network is impaired, but 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.
