dt4trsvp.htm

Specific feature benefits are located in the respective documents listed in the "Supported IOS Features" section

Restrictions

Modem and digital services are supported by using the 324 UPC, 24 T1s or 24 E1s trunk card and the 216 UPC features of the E1 and T3 trunkcards.

Online Insertion and Removal

TheInsertion and Removal (OIR) graceful procedure is strongly recommended. It is also recommended that the card replaced is the same type as the card removed.

RSVP

RSVP fair-queue is not supported in this release.

Call Admission Control (CAC)

Call Admission Control (CAC) can be optimized to improve performance when the system is exposed to CPU spikes. The adjustments include the monitored CPU threshold and the call refusal period setting.

Debit Card Applications

Debit Card applications supports 8 calls per second (cps) rate per Route Switch Controller (RSC).

IP-Side IVR

IP side IVR supports no more than 672 calls (1CT3) at 3-4 calls per second (cps). If the recommended values are exceeded, a high CPU utilization may be observed, resulting in excessive call disconnects.

A mixed environment of 500 IP side IVR calls at 2-3 cps and 500 Direct-Inward-Dial (DID) calls at 2 cps is supported.

10 ms Sampling

The AS5850 supports 4 CT3s worth of traffic per chassis (dual RSCs) with 20ms sampling VAD ON or Off or 10ms VAD ON regardless of codec used. Support for 10ms VAD OFF is required, the session is supported at 1060 per RSC (2120 per chassis) with the addition of one more 324 UPC card per RSC. For the initial release, the use of 10 ms shall be enforced for the system supported per RSC.

RSC Failover Redundancy

RSC failover redundancy requires a Session Initiation Protocol (SIP) proxy server or gatekeeper. Reallocation of resources occurs with failure of an RSC. The reallocation mechanism is not supported when invoked by fluctuation of either the Ethernet interface or Public Switched Telephone Network (PSTN) trunk interface

Codecs Supported on the Cisco AS5850:

g711u-law

g711a-law

g729r8

g723r63

Determining Platform Support Through Cisco Feature Navigator

Cisco IOS software is packaged in feature sets that support specific platforms. To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.

Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common.

To access Cisco Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions at http://www.cisco.com/register.

Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

http://www.cisco.com/go/fn

Availability of Cisco IOS Software Images

Platform support for particular Cisco IOS software releases is dependent on the availability of the software images for those platforms. Software images for some platforms may be deferred, delayed, or changed without prior notice. For updated information about platform support and availability of software images for each Cisco IOS software release, refer to the online release notes or, if supported, Cisco Feature Navigator.
