PERFORMANCE SPECIFICATIONS
The performance targets defined in this section are for the entire linecard comprised of both chips
in the Intelligent Access voice chipsets unless otherwise noted. Specifications for the individual chips
in the set will be published separately (see note 1). T

Voice Chipsets System Target Specifications
Notes:
1. Not tested or partially-tested in production.
2. These numbers are only valid when an ISLIC device operates with an ISLAC device, because the ISLAC
generates the anti-sat feed characteristic. When the Intelligent Access voice chipsets operate in the normal
feed region, the performance is controlled by the ISLIC device. See appropriate ISLIC data sheet for
specific PSRR.
