Hello Allen,
I believe Cisco doesn't have something that directly competes with the ISS-4000 since Cisco likes the more flexible / moduluar approach to designing a network.
The Cisco solution would consist of various hardware pieces depending on the actual topology and needs, with the hardware capped and managed using Building Broadband Service Manager software.
The ISS-4000 is a all in one box, even the PMS billing system is included in the box.
The Cisco Solution would me a more flexible, scalable system, where the ISS-4000 would be more static one.
