COMPOSITION OF A CAMPUS-RS SYSTEM
Campus-RS products accommodate a wide range of network interfaces and access speeds in a single platform solution. A Campus-RS system comprises these primary elements:
•Campus-RS desktop unit—The desktop unit provides a DSL (WAN) interface that connects to a line unit (DSL interface) in a Campus-Star chassis or back-to-back with another desktop unit DSL interface. You can then install any of the customer interface cards listed on page 120 for the customer-side network connection.
•Campus-Star chassis—This chassis or concentrator provides aggregation for up to 14 DSL line connections. Each line connection is made using a DSL line unit that connects to a DSL line unit in another Star Chassis or to the DSL interface of a desktop unit. You can then install any one of the customer interface cards listed below to complement each DSL line unit in the chassis for the customer-side network connection.
You can install a Campus-RS Management Unit (CMU) into the chassis for SNMP management of components in the chassis and for management of elements attached to the chassis.
•Customer interface cards—For connection to the customer network for voice, video, and data, the following interface cards are available to install into the desktop unit or the Campus-Star chassis:
–serial data interfaces such as RS-449, RS-530, RS-530A, V.35, and X.21 for connections to a router or other data equipment (with this customer interface card, the maximum DSL line connection rate can be up to 4.608 Mbps)
–flex interface with two serial data ports for RS-449, RS-530, RS-530A, V.35, or X.21 interfaces and one DSX-1 voice interface (with this customer interface card, the maximum DSL line connection rate can be up to 1.544 Mbps)
–CSU/DSU interface (with this customer interface card, the maximum DSL line connection rate can be up to 1.544 Mbps)
–G.703 (E1) interface (with this customer interface card, the maximum DSL line connection rate can be up to 2.048 Mbps)
–10/100Base-T bridge/router interface (with this customer interface card, the maximum DSL line connection rate can be up to 4.6 Mbps)
