Specifically designed for on-site deployment, the DSAN supports two auxiliary
inputs, allowing customers to provide up to eight customized local channels (e.g.,
security cameras, DVD players, local bulletin boards, etc.) for their residents or
guests. The channel lineups for each DSAN can also be configured independently to
support specific customer needs, allowing service providers to offer a wider variety
of content. Additionally, the DSAN supports digital pass-through, making it an
extremely flexible platform that is ideal for customers wanting additional services
such as HD, VOD, Data, and Voice.

The analog output is recreated from portions of the digital plant spectrum, and
occupies the 54 to 552 MHz frequency range designated for CATV analog channels.
The combined digital output (564 MHz to 1 GHz) is available for use by compatible
receiving equipment such as a set-top box, EMTA, or cable modem.
