Release Notes for the Cisco ATA 186 and Cisco ATA 188 Release 3.2(1) for SIP

These release notes describe enhancements and resolved issues for the Cisco ATA 186 and the Cisco ATA 188 for Release 3.2 (1) for the SIP protocol.

Refer also to the Release Notes for the Cisco ATA 186 and Cisco ATA 188 Release 3.2 for information about that release:

In addition, refer to the Cisco ATA administrator's guide for your protocol at the following location:

Introduction to the Cisco ATA Analog Telephone Adaptor

The Cisco ATA is an analog telephone adaptor that allows traditional analog telephones to operate on IP-based telephony networks. The Cisco ATA supports two voice ports, each with its own independent telephone number.

Two Cisco ATA products are available to Cisco customers—the Cisco ATA 186 and the Cisco ATA 188. Both products run the same software and have two voice ports. The Cisco ATA 186 has one RJ45 port that provides access to an Ethernet network. The Cisco ATA 188 has an Ethernet switch and two RJ45 ports—one for accessing an Ethernet network and one for connecting a downstream Ethernet device such as a PC.

Downloading and Upgrading the Software

Before you can use the Cisco ATA Release 3.2 (1), you must first download and upgrade the Cisco ATA software. You can download the software, after logging in, at:

Note If you are using the Cisco ATA executable-file-upgrade method, check with the administrator of the TFTP server to make sure that the TFTP upgrade method is disabled. Otherwise, the Cisco ATA might downgrade to an old image via TFTP.

For more information about downloading and upgrading software, see the Cisco ATA administrator's guides for the signaling protocol you are using. The administrator's guides can be found at the following location:

Support Millisecond Resolution for RingOnOffTime

The Cisco ATA now offers milliseconds resolution for the ring ON and OFF time as specified in the RingOnOffTime parameter.

If ring ON or OFF time is greater than 100, the unit of time is in milliseconds. If the time is less than 100, the unit of time is in seconds.

For detailed information about the RingOnOffTime parameter, see the administrator's guide:

http://www.cisco.com/univercd/cc/td/doc/product/voice/ata/ataadmn/sip30ad/sip88ape.htm#wp1116754

To specify a ring ON time of 0.75 seconds, ring OFF time of 7.5 seconds, and ring frequency of 25, the parameter value is 750,7500,25.

Power-Denial Control

Polarity parameter bit 4 can be used to enable or disable power denial on both FXS ports. When the bit value is 0 (default), power denial is enabled. When the bit value is 1, power denial is disabled.

For more information about the Polarity parameter, see the administrator's guide:

http://www.cisco.com/univercd/cc/td/doc/product/voice/ata/ataadmn/sip30ad/sip88ape.htm#wp1027166

Enhancement to Dial Plan 'N' Rule

This is an extension of the original dial plan 'N' rule that is described in the Cisco ATA 3.2 Release Notes at the following location.

The dial plan 'N' rule introduced in release 3.2 has been enhanced to apply to all outgoing numbers, including emergency numbers.

•

T—The letter used to indicate the available options in applying the N-rule. These options are:

–

C—Apply normalization without adding the leading plus sign; do not apply denormalization.

–

D—Apply normalization without adding the leading plus sign; apply denormalization also.

–

E—Apply normalization and add the leading plus sign; do not apply denormalization.

–

F—Apply normalization and add the leading plus sign; apply denormalization also.

•

tttt—The triggering subrule for normalization. This could be a subrule matching with or without the leading logical not (^).

The following examples assume a telephone number in San Jose, CA with an area code of 408.

This command applies normalization to outgoing numbers with a length not less than 6; also applies denormalization.

This command applies to outgoing numbers except these with length 3 or 5; also applies denormalization.

Resolved Issues for Release 3.2 (1)

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 automatically provides recommended solutions. If your issue is not resolved using the recommended resources, your service request will be 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.

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.
